Description

 本発明は一台で住居の複数ゾーンの換気空調を行なう主として高気密・高断熱住宅に適用される換気空調装置に関するものである。 The present invention relates to a ventilation air conditioner mainly applied to a highly airtight and highly insulated house which performs ventilation and air conditioning of a plurality of zones of a house by one unit.

 換気空調装置には、特公平4ー40615号公報に示されているように熱交換換気機能と冷暖房機能とを兼備したものがある。いずれも、換気空調装置の本体は、住居の一ゾーンに設置され、当該住居の全体の負荷に対応できる換気と空調能力を備え、給気ダクトにより各ゾーンに室外から取り込んだ新鮮な空気と室内の空気とを混合した加工空気をそれぞれ供給するようにシステム構成される。例えば、特開平2ー195146号公報のものでは、本体に組込まれた能力可変の熱源発生機により発生する温風又は冷風を能力可変の送風機によりダクトを介して各ゾーンに供給するようにシステム構成される。 Some ventilating air conditioners have both a heat exchange ventilation function and a cooling / heating function as disclosed in Japanese Patent Publication No. 4-40615. In each case, the main body of the ventilation and air-conditioning system is installed in one zone of the dwelling, equipped with ventilation and air-conditioning capacity that can cope with the entire load of the dwelling. The system is configured to supply the processing air mixed with the air. For example, Japanese Patent Application Laid-Open No. 2-195146 discloses a system configuration in which hot air or cold air generated by a variable-capacity heat source generator incorporated in a main body is supplied to each zone via a duct by a variable-capacity blower. Is done.

 こうした換気空調装置においてその運転にかかる制御装置は、従来においては冷暖房機能だけの一般的な空調装置に採用されている制御装置がそのまま適用されていることが多い。即ち、〈1〉特開昭61ー31843号公報、〈2〉特開昭62ー190342号公報、〈3〉特開平4ー236050号公報、〈4〉特開平4ー180500号公報、〈5〉特開平6ー34181号公報、〈6〉特開平6ー42803号公報にそれぞれ示されているような制御装置が用いられている。 In such a ventilation air-conditioning system, a control system used for a general air-conditioning system having only a cooling and heating function is often used as it is as a control system for its operation. That is, <1> JP-A-61-31843, <2> JP-A-62-190342, <3> JP-A-4-236050, <4> JP-A-4-180500, <5> Control devices as disclosed in JP-A-6-34181 and <6> JP-A-6-42803 are used.

 上記した公報のうちの〈1〉によるものは、設定される設定温度と検出される実温度との温度差を検出し、設定温度に実温度が達するまでの時間の長短により複数の制御ゾーンを設定し、各制御ゾーンに対応して空調用送風機への印加電圧を制御している。〈2〉によるものは、室温が下がり勾配か昇り勾配かの場合でそれぞれ複数の制御ゾーンを設定し、ゾーンを越えるかどうかで空調用送風機を周波数制御している。〈3〉〜〈6〉によるものはファジー演算を用いたもので、温度差により、丁度良い、やや差がある、差がある等に分け、さらに前回の温度差の時間的変化率を組み合わせて温度制御している。 According to <1> of the above publications, a temperature difference between a set temperature to be set and an actual temperature to be detected is detected, and a plurality of control zones are determined depending on a length of time until the actual temperature reaches the set temperature. It sets and controls the voltage applied to the air-conditioning blower corresponding to each control zone. In the method according to <2>, a plurality of control zones are set depending on whether the room temperature is falling or rising, and the frequency of the air-conditioning blower is controlled depending on whether the temperature exceeds the zone. <3> to <6> use fuzzy arithmetic, and are divided into just good, slightly different, and different according to the temperature difference, and are combined with the temporal change rate of the previous temperature difference. Temperature controlled.

 また、熱源発生装置を制御したり、例えば、特開平2ー50040号公報に示されているように熱源発生手段と空調用送風機の双方を制御して設定温度に到達させようとするものもある。これは冷暖房能力が熱源発生装置からの熱源の量と空調用送風機の風量とに相関することに着目し、熱源の流量と風量を関連づけて制御するようにしたものである。 Further, there is also a device that controls a heat source generating device or controls both a heat source generating unit and an air-conditioning blower to reach a set temperature, for example, as disclosed in JP-A-2-50040. . This focuses attention on the fact that the cooling and heating capacity correlates with the amount of heat source from the heat source generating device and the air volume of the air-conditioning blower, and controls the flow rate and the air volume of the heat source in association with each other.

 上記の他に換気と空調とを関係付けたものも有る。この種のものは特開平1ー256748号公報や特開平4ー110553号公報に示されているような、空調運転と換気ファンとを連動の関係にも独立の関係にもできるように制御する仕方や、換気モード運転では換気送風機を強運転させるように制御する仕方が採用されている。 の 他 In addition to the above, there are some that relate ventilation and air conditioning. This type is controlled so that the air-conditioning operation and the ventilation fan can be linked or independent, as disclosed in JP-A-1-256748 and JP-A-4-110553. In the ventilation mode operation, a method of controlling the ventilation blower to operate strongly is adopted.

特公平4ー40615号公報Japanese Patent Publication No. 4-40615

 上記のような従来の制御装置においては、冷暖房にかかる空調についてはそれぞれその制御機能に応じた温度に関する状態量の制御がなされるが、換気に関する状態量については制御対象から外れているか、空調とは切り離して制御しているため、高気密住宅では快適性の高い換気空調雰囲気が得難いといった問題点がある。 In the conventional control device as described above, for the air conditioning related to cooling and heating, the state quantity related to the temperature is controlled in accordance with the respective control functions. However, there is a problem that it is difficult to obtain a highly air-conditioned and air-conditioned atmosphere in a highly airtight house because the air conditioner is controlled separately.

 即ち、高気密住宅においては換気を換気装置にほぼ全面的に依存することになるため、換気についても十分に配慮する必要がある。しかしながら、換気のために取り込まれる外気がそのまま空調用の加工空気として加工され、各ゾーンへ供給される換気空調装置では、温度制御により空調用送風機が停止すると、その空調用送風機により加工空気が供給されていたゾーンへの新鮮な空気の供給も停止してしまう。特開平4ー324042号公報にはこうした不都合を解消する技術が示されている。 That is, in a highly airtight house, the ventilation depends almost entirely on the ventilation system, so it is necessary to give due consideration to ventilation. However, the outside air taken in for ventilation is processed as it is as processing air for air conditioning, and in a ventilation air-conditioning system that is supplied to each zone, when the air-conditioning blower stops due to temperature control, the processing air is supplied by the air-conditioning blower. The supply of fresh air to the zone that was being shut down also stops. Japanese Patent Application Laid-Open No. Hei 4-324404 discloses a technique for solving such a problem.

 これは、全てのゾーンの室温が設定温度に達し、空調用送風機が全て停止されると、強制的に空調用送風機を弱ノッチで運転させ、新鮮な外気の供給を継続させるものであるが、いずれか一つでも設定温度に達していない間は、既に設定温度に達している他のゾーンへは外気の導入が図られないといった難点がある。 This means that when the room temperature of all zones reaches the set temperature and all the air-conditioning blowers are stopped, the air-conditioning blowers are forcibly operated at a weak notch and the supply of fresh outside air is continued, While at least one of the zones has not reached the set temperature, there is a drawback that outside air cannot be introduced into another zone that has already reached the set temperature.

 換気と空調とを関連付けた特開平1ー256748号公報や特開平4ー110553号公報に示されている技術も、一台の換気空調装置で住居全体の換気空調を行なう換気空調装置では適用することができない。即ち、全てのゾーンから換気モード運転の要求がなされないと、換気を十分に行なう運転にはならず、換気と空調との調整が利かない。 The techniques disclosed in JP-A-1-256748 and JP-A-4-110553 in which ventilation and air-conditioning are related to each other are also applied to a ventilating air-conditioning apparatus that performs ventilation and air-conditioning of an entire house with one ventilating air-conditioning apparatus. I can't. That is, if the request for the ventilation mode operation is not made from all the zones, the operation cannot be performed to perform the ventilation sufficiently, and the adjustment between the ventilation and the air conditioning is not effective.

 本発明は上記した従来の問題点を解消するためになされたもので、その課題とするところは、換気機能と空調機能とが結合し、複数ゾーンに換気空調を行なう換気空調装置の空調機能と換気機能とを調和的に働かせてより快適性の高い換気空調雰囲気が形成できるようにすることであり、換気空調装置の消費電力や運転音を低減させることであり、換気空調装置の除湿機能を向上させることである。 The present invention has been made in order to solve the above-described conventional problems, and the subject thereof is that the ventilation function and the air conditioning function are combined, and the air conditioning function of a ventilation air conditioning apparatus that performs ventilation air conditioning in a plurality of zones is provided. The purpose is to make the ventilation and air conditioning atmosphere more comfortable by harmonizing with the ventilation function, to reduce the power consumption and operation noise of the ventilation and air conditioning system, and to improve the dehumidification function of the ventilation and air conditioning system. It is to improve.

 給気用送風機によって取り入れられる外気と、排気用送風機によって排気される住居内空気とを換気用熱交換器により熱交換させ、熱交換後の外気を、風量可変の空調用送風機と、この空調用送風機の形成する空気流を加工する空調用熱交換器を備えた複数系統の空調機能部に住居内空気とともにそのまま供給して住居の各ゾーンに空調機能部により形成される加工空気をそれぞれ供給するように構成した装置本体に、空調機能部の各空調用送風機の運転を制御する制御装置を組込んだもので、その制御装置を各空調機能部に対応する各ゾーンに配置され、室内温度を検知する室温検知機能と、当該ゾーンの室温を設定する温度設定機能を有するコントローラに接続し、制御装置によりコントローラからの室内温度と設定温度とからその差温度と、該差温度の時間変化量とを求め、差温度とその時間変化量とに応じた調節信号を形成して、当該ゾーンに対応する空調機能部の空調用送風機のノッチを多段階に切替えて、できるだけ当該空調用送風機を停止させずに設定温度に到達するように制御する手段を採用する。 The outside air taken in by the air supply blower and the air in the house exhausted by the exhaust air blower are heat-exchanged by a ventilation heat exchanger, and the heat-exchanged outside air is supplied to an air-conditioning blower having a variable air volume, and A plurality of air-conditioning units equipped with air-conditioning heat exchangers for processing the air flow formed by the blower are supplied as they are together with the air in the house, and the processing air formed by the air-conditioning units is supplied to each zone of the house. A control device for controlling the operation of each air-conditioning blower of the air-conditioning function unit is incorporated in the device body configured as described above, and the control device is disposed in each zone corresponding to each air-conditioning function unit, and the indoor temperature is controlled. It is connected to a controller that has a room temperature detection function to detect the temperature and a temperature setting function to set the room temperature in the zone, and the control device controls the difference between the room temperature from the controller and the set temperature. The temperature and the amount of time change of the temperature difference are obtained, and an adjustment signal corresponding to the temperature difference and the time change amount is formed, and the notch of the air-conditioning blower of the air-conditioning function unit corresponding to the zone is multi-staged. A means for switching and controlling so as to reach the set temperature without stopping the air-conditioning blower as much as possible is adopted.

 給気用送風機によって取り入れられる外気と、排気用送風機によって排気される住居内空気とを換気用熱交換器により熱交換させ、熱交換後の外気を、風量可変の空調用送風機と、この空調用送風機の形成する空気流を加工する空調用熱交換器を備えた複数系統の空調機能部に住居内空気とともにそのまま供給して住居の各ゾーンに上記空調機能部により形成される加工空気をそれぞれ供給するように構成した装置本体に、空調機能部の各空調用送風機の運転と空調用熱交換器へ熱源を供給する熱源発生機とを制御する制御装置を組込んだもので、その制御装置を各空調機能部に対応する各ゾーンに配置され、室内温度を検知する室温検知機能と、当該ゾーンの室温を設定する温度設定機能を有するコントローラに接続し、制御装置によりコントローラからの室内温度と設定温度とからその差温度と、該差温度の時間変化量とを求め、差温度とその時間変化量と熱源の流量に応じた調節信号を形成して、設定温度の最も高いコントローラに従って熱源発生機の熱源の流量を制御するとともに、当該ゾーンに対応する空調機能部の空調用送風機のノッチを多段階に切替えて、できるだけ当該空調用送風機を停止させずに設定温度に到達するように制御する手段を採用する。 The outside air taken in by the air supply blower and the air in the house exhausted by the exhaust air blower are heat-exchanged by a ventilation heat exchanger, and the heat-exchanged outside air is supplied to an air-conditioning blower having a variable air volume, and The air-conditioning heat exchanger for processing the air flow formed by the blower is supplied directly to the air-conditioning function units of multiple systems together with the air in the house, and the processing air formed by the air-conditioning function units is supplied to each zone of the house. A control device that controls the operation of each air-conditioning blower of the air-conditioning function unit and a heat source generator that supplies a heat source to the air-conditioning heat exchanger is incorporated in the device main body configured to perform the control. Connected to a controller that is located in each zone corresponding to each air conditioning function unit and has a room temperature detection function to detect the room temperature and a temperature setting function to set the room temperature in the zone. The temperature difference between the room temperature and the set temperature from the controller and the time change amount of the difference temperature are obtained, and an adjustment signal corresponding to the difference temperature, the time change amount and the flow rate of the heat source is formed, and the set temperature is calculated. In addition to controlling the flow rate of the heat source of the heat source generator according to the highest controller, the notch of the air-conditioning fan of the air-conditioning function section corresponding to the zone is switched in multiple stages, and the set temperature is maintained as much as possible without stopping the air-conditioning fan. Employ means for controlling to reach.

 給気用送風機の運転によって取り入れられる外気と、排気用送風機の運転によって排気される住居内空気とが換気用熱交換器により熱交換される。熱交換後の外気は、空調機能部の運転により取り入れられる住居内空気と混合して空調機能部により加工空気として住居の各ゾーンへ供給される。この時、装置本体に組込まれた制御装置は、各空調機能部に対応する各ゾーンに配置されたコントローラから得られる室内温度と設定温度との情報から両者間の差温度と、該差温度の時間変化量とを求め、差温度とその時間変化量とに応じた調節信号を形成して、当該ゾーンに対応する空調機能部の空調用送風機のノッチを多段階に切替えて、当該ゾーンの室内温度が設定温度に到達するように制御する。空調機能部の空調用送風機は室内温度が設定温度に到達するように例えば強ノッチから中ノッチを経て弱ノッチに、又は弱ノッチから中ノッチを経て強ノッチに到達するように段階的にノッチが移行する。従って、空調用送風機はなるべく停止しないように制御され、温度制御幅も小さくなる。 外 Heat exchange between the outside air taken in by the operation of the air supply fan and the house air exhausted by the operation of the exhaust air blower is performed by the ventilation heat exchanger. The outside air after the heat exchange is mixed with the air in the house taken in by the operation of the air conditioning function unit, and supplied to each zone of the house as processing air by the air conditioning function unit. At this time, the control device incorporated in the device main body determines the difference temperature between the room temperature and the set temperature based on the information on the room temperature and the set temperature obtained from the controllers arranged in the respective zones corresponding to the respective air-conditioning function units. The time change amount is obtained, an adjustment signal corresponding to the difference temperature and the time change amount is formed, and the notch of the air-conditioning blower of the air-conditioning function unit corresponding to the zone is switched in multiple stages, and the indoor of the zone is changed. Control so that the temperature reaches the set temperature. The air-conditioning blower of the air-conditioning function unit has a notch in a stepwise manner so that the indoor temperature reaches the set temperature, for example, from a strong notch to a weak notch via a middle notch, or from a weak notch to a strong notch via a middle notch. Transition. Therefore, the air-conditioning blower is controlled so as not to stop as much as possible, and the temperature control width is also reduced.

 給気用送風機の運転によって取り入れられる外気と、排気用送風機の運転によって排気される住居内空気とが換気用熱交換器により熱交換される。熱交換後の外気は、空調機能部の運転により取り入れられる住居内空気と混合して空調機能部により加工空気として住居の各ゾーンへ供給される。この時、装置本体に組込まれた制御装置は、各空調機能部に対応する各ゾーンに配置されたコントローラから得られる室内温度と設定温度との情報から両者間の差温度と、該差温度の時間変化量とを求め、差温度とその時間変化量と空調用熱交換器に流れる熱源の流量に応じた調節信号を形成して、設定温度の最も高いコントローラに従って熱源発生機の熱源の流量を制御するとともに、当該ゾーンに対応する空調機能部の空調用送風機のノッチを多段階に切替えて、できるだけ当該空調用送風機を停止させずに設定温度に到達するように制御する。 外 Heat exchange between the outside air taken in by the operation of the air supply fan and the house air exhausted by the operation of the exhaust air blower is performed by the ventilation heat exchanger. The outside air after the heat exchange is mixed with the air in the house taken in by the operation of the air conditioning function unit, and supplied to each zone of the house as processing air by the air conditioning function unit. At this time, the control device incorporated in the device main body determines the difference temperature between the room temperature and the set temperature based on the information on the room temperature and the set temperature obtained from the controllers arranged in the respective zones corresponding to the respective air-conditioning function units. Determine the amount of change over time, form an adjustment signal according to the difference temperature, the amount of change over time and the flow rate of the heat source flowing through the air conditioning heat exchanger, and determine the flow rate of the heat source of the heat source generator according to the controller with the highest set temperature. In addition to the control, the notch of the air-conditioning blower of the air-conditioning function unit corresponding to the zone is switched in multiple stages, and control is performed so as to reach the set temperature without stopping the air-conditioning blower as much as possible.

 給気用送風機の運転によって取り入れられる外気と、排気用送風機の運転によって排気される住居内空気とが換気用熱交換器により熱交換される。熱交換後の外気は、空調機能部の運転により取り入れられる住居内空気と混合して空調機能部により加工空気として住居の各ゾーンへ供給される。この時、装置本体に組込まれた制御装置は、各空調機能部に対応する各ゾーンに配置されたコントローラから得られる室内温度と設定温度との情報から両者間の差温度と、該差温度の時間変化量とを求め、差温度とその時間変化量とに応じた調節信号を形成して、当該ゾーンに対応する空調機能部の空調用送風機のノッチを多段階に切替えて、当該ゾーンの室内温度が設定温度に到達するように制御する。空調機能部の空調用送風機は室内温度が設定温度に到達するように例えば強ノッチから中ノッチを経て弱ノッチに、又は弱ノッチから中ノッチを経て強ノッチに到達するように段階的にノッチが移行する。従って、空調用送風機はなるべく停止しないように制御され、温度制御幅も小さくなり、空調機能と換気機能とが調和的に働き、高気密住宅に対してより快適性の高い換気空調雰囲気を形成できる。 外 Heat exchange between the outside air taken in by the operation of the air supply fan and the house air exhausted by the operation of the exhaust air blower is performed by the ventilation heat exchanger. The outside air after the heat exchange is mixed with the air in the house taken in by the operation of the air conditioning function unit, and supplied to each zone of the house as processing air by the air conditioning function unit. At this time, the control device incorporated in the device main body determines the difference temperature between the room temperature and the set temperature based on the information on the room temperature and the set temperature obtained from the controllers arranged in the respective zones corresponding to the respective air-conditioning function units. The time change amount is obtained, an adjustment signal corresponding to the difference temperature and the time change amount is formed, and the notch of the air-conditioning blower of the air-conditioning function unit corresponding to the zone is switched in multiple stages, and the indoor of the zone is changed. Control so that the temperature reaches the set temperature. The air-conditioning blower of the air-conditioning function unit has a notch in a stepwise manner so that the indoor temperature reaches the set temperature, for example, from a strong notch to a weak notch via a middle notch, or from a weak notch to a strong notch via a middle notch. Transition. Therefore, the air-conditioning blower is controlled so as not to stop as much as possible, the temperature control width is also reduced, the air-conditioning function and the ventilation function work in harmony, and a more comfortable ventilation air-conditioning atmosphere can be formed in a highly airtight house. .

 給気用送風機の運転によって取り入れられる外気と、排気用送風機の運転によって排気される住居内空気とが換気用熱交換器により熱交換される。熱交換後の外気は、空調機能部の運転により取り入れられる住居内空気と混合して空調機能部により加工空気として住居の各ゾーンへ供給される。この時、装置本体に組込まれた制御装置は、各空調機能部に対応する各ゾーンに配置されたコントローラから得られる室内温度と設定温度との情報から両者間の差温度と、該差温度の時間変化量とを求め、差温度とその時間変化量と空調用熱交換器に流れる熱源の流量に応じた調節信号を形成して、設定温度の最も高いコントローラに従って熱源発生機の熱源の流量を制御するとともに、当該ゾーンに対応する空調機能部の空調用送風機のノッチを多段階に切替えて、できるだけ当該空調用送風機を停止させずに設定温度に到達するように制御されるので、温度制御幅も小さくなり、空調機能と換気機能とが調和的に働き、高気密住宅に対してより快適性の高い換気空調雰囲気を低騒音で形成できる。 外 Heat exchange between the outside air taken in by the operation of the air supply fan and the house air exhausted by the operation of the exhaust air blower is performed by the ventilation heat exchanger. The outside air after the heat exchange is mixed with the air in the house taken in by the operation of the air conditioning function unit, and supplied to each zone of the house as processing air by the air conditioning function unit.

In addition to controlling, the notch of the air-conditioning fan of the air-conditioning function unit corresponding to the zone is switched in multiple stages, and the air-conditioning fan is controlled so as to reach the set temperature without stopping the air-conditioning fan as much as possible. The air-conditioning function and the ventilation function work in harmony, and a highly comfortable ventilation and air-conditioning atmosphere can be formed in a highly airtight house with low noise.

A connection port for duct connection is provided at an outdoor exhaust port, which is an outlet end of the exhaust passage, and is connected to the outside of the house via an exhaust duct 13. The air supply passage of the ventilation section 2 has an outside air intake opening to one side of the main body casing as an inlet end, and passes through the air supply blower 5 from the other working fluid passage of the ventilation heat exchanger 6 to the indoor air intake 12. It is configured as a series of passages leading to an air supply opening formed in a partition wall facing. A connection port for duct connection is provided at an outside air intake, which is an inlet end of the air supply passage, and is connected to the outside of the house via the intake duct 14.

 空調部3の各空調機能体7の加工空気通路は、いずれも室内空気取入口12を入口端とし、空調用熱交換器10,11を通過して空調用送風機8,9を経て本体ケーシングの側部に開口した空気供給口に至る一連の通路として構成され、各空気供給口にはダクト接続するための接続口が設けられ、それぞれ給気ダクト15を介して個々に供給対象の各ゾーンB,Cに連絡される。図例のように2個の空調機能体7で空調部3が構成される場合には、一方の空調機能体7の加工空気通路の入口側は換気部2の排気開口部に対応する側に位置され、他方の空調機能体7の加工空気通路の入口側は換気部2の給気開口部に対応する側に位置される。2個以上の空調機能体7で空調部3が構成される場合には、特定の空調機能体7とそうでない空調機能体7に対して上述の換気部2側との関係が構成されることになる。 Each of the processing air passages of the air conditioning function bodies 7 of the air conditioning unit 3 has the indoor air intake 12 as an inlet end, passes through the air conditioning heat exchangers 10 and 11, passes through the air conditioning blowers 8 and 9, and is provided with a main body casing. Each air supply port is provided with a connection port for duct connection, and each air supply port is individually provided via an air supply duct 15 to each of the zones B to be supplied. , C. In the case where the air conditioner 3 is composed of two air conditioners 7 as shown in the figure, the inlet side of the processing air passage of one air conditioner 7 is located on the side corresponding to the exhaust opening of the ventilator 2. The inlet side of the processing air passage of the other air conditioning function body 7 is located on the side corresponding to the air supply opening of the ventilation unit 2. When the air-conditioning unit 3 is configured by two or more air-conditioning function bodies 7, the relationship between the specific air-conditioning function body 7 and the other air-conditioning function bodies 7 with the above-described ventilation unit 2 side is configured. become.

 この実施例の空調機能体7は、各空調用送風機8,9部分を仕切板で仕切り、空調用熱交換器10,11を共用するかたちに構成されていて、各空調機能体7には換気部2からの熱交換後の外気と、室内空気取入口12からのゾーンAの空気が混合されて分流していく。空調用熱交換器10は暖房用熱源発生機16に接続され、暖房用熱源発生機16から温水などの暖房用熱源の供給を受ける。また、空調用熱交換器11は冷房用熱源発生機17に接続され、冷房用熱源発生機17から冷房用熱源の供給を受ける。 The air-conditioning function body 7 of this embodiment is configured such that the air-conditioning blowers 8, 9 are separated by a partition plate, and the air-conditioning heat exchangers 10, 11 are shared. The outside air after the heat exchange from the section 2 and the air in the zone A from the indoor air intake 12 are mixed and diverted. The air conditioning heat exchanger 10 is connected to a heating heat source generator 16 and receives a heating heat source such as hot water from the heating heat source generator 16. The air-conditioning heat exchanger 11 is connected to a cooling heat source generator 17 and receives supply of a cooling heat source from the cooling heat source generator 17.

 暖房用熱源又は冷房用熱源を空調用熱交換器10又は空調用熱交換器11に流通させ、空調用送風機8,9を動作させて空調部3を運転させ、給気用送風機5と排気用送風機4とを動作させて装置本体1を運転させると、給気通路から取入れられた住居外の新鮮な外気は、換気用熱交換器6において排気流と熱交換した後、給気開口部に吹出され、室内空気取入口12から吸込まれるゾーンAの空気と混合して各空調機能体7の加工空気通路に流れ込み、暖冷房用に加工されて当該空気供給口から給気ダクト15を介して供給対象のゾーンB,Cに加工空気が供給される。一方、排気用送風機4の運転により吸込まれたゾーンAの空気は、排気開口部から換気用熱交換器6を経て室外排気口に至り、排気ダクト13を介して住居外へ排気される。即ち、新鮮な外気の導入と汚濁したゾーンAの空気の住居外への排気による換気が、暖冷房と並行して行なわれる。 The heat source for heating or the heat source for cooling is circulated to the heat exchanger for air conditioning 10 or the heat exchanger for air conditioning, the air conditioners 8 and 9 are operated to operate the air conditioner 3, and the air supply fan 5 and exhaust air When the main body 1 is operated by operating the blower 4, fresh outside air outside the house taken in from the air supply passage exchanges heat with the exhaust air flow in the ventilation heat exchanger 6, and then enters the air supply opening. The air is blown out, mixed with the air in the zone A sucked from the indoor air inlet 12, flows into the processing air passage of each air conditioning function body 7, is processed for heating and cooling, and is supplied from the air supply port via the air supply duct 15. Thus, the processing air is supplied to the zones B and C to be supplied. On the other hand, the air in the zone A sucked by the operation of the exhaust blower 4 reaches the outdoor exhaust port from the exhaust opening through the ventilation heat exchanger 6, and is exhausted outside the house via the exhaust duct 13. That is, the introduction of fresh outside air and the ventilation of the polluted zone A by exhausting the air outside the house are performed in parallel with the heating and cooling.

 次に、図2〜図6により上記構成の換気空調システムにおける制御系について説明する。装置本体1には、装置本体1の運転停止や冷暖房の切替えや各ゾーンA,B,Cの空調の運転停止などの制御機能を持つ制御装置18が組込まれている。この制御装置18は、排気用送風機4,給気用送風機5,空調用送風機8,9及び暖房用熱源発生機16並びに冷房用熱源発生機17と接続され、これらをそれぞれ制御する。装置本体1により給気ダクト15を介して空調される各ゾーンB,Cには制御装置18と通信線によって接続されたコントローラ19がそれぞれゾーンB,C毎に設置されている。 Next, a control system in the ventilation / air-conditioning system having the above configuration will be described with reference to FIGS. A control device 18 having a control function of stopping operation of the device main body 1, switching between cooling and heating, and stopping operation of air conditioning in each of the zones A, B, and C is incorporated in the device main body 1. The control device 18 is connected to the exhaust blower 4, the air supply blower 5, the air conditioner blowers 8, 9 and the heating heat source generator 16 and the cooling heat source generator 17, and controls these. In each of the zones B and C that are air-conditioned by the apparatus main body 1 via the air supply duct 15, a controller 19 connected to a control device 18 by a communication line is installed for each of the zones B and C.

 この各コントローラ19は、システム全体の運転停止、空調モード(冷暖房)の設定にかかる設定機能と、ゾーンB,C毎の温度設定機能や当該ゾーンB,Cの室温検知機能や運転停止など個別の設定にかかる機能を備えている。また、換気空調システム全体とゾーンB,Cの運転状態を表示する表示機能も備え、図2に示すように制御装置18と通信する。 Each controller 19 has a setting function for stopping the operation of the entire system, setting an air conditioning mode (cooling / heating), a temperature setting function for each of the zones B and C, a room temperature detecting function for the zones B and C, and an individual operation such as a stop. It has a function for setting. In addition, a display function for displaying the operation state of the entire ventilation air conditioning system and zones B and C is also provided, and communicates with the control device 18 as shown in FIG.

 この実施例1の制御装置18は、空調用送風機8,9と暖房用熱源発生機16又は冷房用熱源発生機17とに対して次のような制御動作を行なうように構成されている。即ち、各コントローラ19から送信されてくる室内温度と設定温度とからその差温度と、該差温度の時間変化量とを求め、差温度とその時間変化量とに応じた調節信号を形成して、当該ゾーンB,Cに対応する空調機能体7の空調用送風機8,9のノッチを多段階に切替えて、設定温度に到達するように制御する。これを図3によって具体的に説明する。制御装置18は、例えばゾーンB(ゾーンCについても同様である)において利用者が設定した設定温度と現在の室内温度の各情報を当該コントローラ19から取り込む。取り込んだ室内温度と設定温度とから差温度算出手段20によりその差温度e(設定温度−室内温度)が算出される。次にこの差温度eが例えば0.5deg変化するΔeまでの時間tが変化量算出手段21により算出される。続いて、差温度eと時間tから調節信号変化量Δcが信号変化量算出手段22により求められる。この調節信号変化量Δcは、図4に示す表に基づいて求められる。 The control device 18 of the first embodiment is configured to perform the following control operations on the air-conditioning blowers 8, 9 and the heating heat source generator 16 or the cooling heat source generator 17. That is, the difference temperature and the time change amount of the difference temperature are obtained from the room temperature and the set temperature transmitted from each controller 19, and an adjustment signal corresponding to the difference temperature and the time change amount is formed. The notches of the air-conditioning fans 8 and 9 of the air-conditioning function body 7 corresponding to the zones B and C are switched in multiple stages to control the temperature to reach the set temperature. This will be specifically described with reference to FIG. The control device 18 fetches, from the controller 19, information on the set temperature set by the user in the zone B (the same applies to the zone C) and the current room temperature, for example. The difference temperature e (set temperature−room temperature) is calculated by the difference temperature calculating means 20 from the taken room temperature and the set temperature. Next, a time t until the difference temperature e changes by, for example, 0.5 deg Δe is calculated by the change amount calculating means 21. Subsequently, the adjustment signal change amount Δc is obtained from the difference temperature e and the time t by the signal change amount calculation means 22. The adjustment signal change amount Δc is obtained based on the table shown in FIG.

 図4における+の記号はノッチを上げる方向を、−はノッチを下げる方向をそれぞれ示し、その数値は現状に対するノッチの変化量を示している。調節信号Cをこうして求めた調節信号変化量Δcの分だけ変化させて新たな調節信号Cが生成され、空調用送風機8,9と暖房用熱源発生機16又は冷房用熱源発生機17に出力される。調節信号Cは図5に示すように空調用送風機8,9のノッチを指示し、暖房用熱源発生機16又は冷房用熱源発生機17のON/OFFを指示するものである。これらの一連の処理は制御装置18に組込まれたマイクロコンピュータ23により行なわれる。 4. In FIG. 4, the symbol + indicates the direction in which the notch is raised, and the symbol − indicates the direction in which the notch is lowered, and the numerical value indicates the amount of change of the notch with respect to the current state. A new adjustment signal C is generated by changing the adjustment signal C by the adjustment signal change amount Δc thus obtained, and is output to the air conditioning fans 8 and 9 and the heating heat source generator 16 or the cooling heat source generator 17. You. As shown in FIG. 5, the adjustment signal C instructs notches of the air conditioner fans 8 and 9 and instructs ON / OFF of the heat source generator 16 for heating or the heat source generator 17 for cooling. These series of processes are performed by the microcomputer 23 incorporated in the control device 18.

 これにより、空調用送風機8,9は例えば図6に示すように室内温度が設定温度に到達するように例えば強ノッチから中ノッチを経て弱ノッチに、又は弱ノッチから中ノッチを経て強ノッチに到達するように段階的にノッチが移行するように制御され、これにより室内温度は図6に示すように安定した温度変化で制御され、温度制御幅も小さくなり快適性が増すことになる。空調用送風機8,9のノッチを手動で行ない、風量をON/OFF制御により行なうようにした従来例では、ノッチの変化と室内温度は例えば冷房負荷が小さい時には図7に示すようになり、室内温度の温度変化が不安定であり、また空調用送風機が停止する時間も長くなる。 As a result, the air-conditioning blowers 8 and 9 are turned from the strong notch to the weak notch via the middle notch or from the weak notch to the weak notch so that the room temperature reaches the set temperature as shown in FIG. 6, for example. The notch is controlled so that the notch shifts in a stepwise manner so that the room temperature is controlled by a stable temperature change as shown in FIG. 6, and the temperature control width is reduced, thereby increasing comfort. In the conventional example in which the notches of the air-conditioning blowers 8 and 9 are manually operated and the air volume is controlled by ON / OFF control, the change of the notches and the room temperature are as shown in FIG. 7 when the cooling load is small, for example. The temperature change of the temperature is unstable, and the time during which the air-conditioning blower is stopped becomes longer.

 空調用送風機8,9が停止している間は、当該空調機能体7に連絡しているゾーンB又はゾーンCには換気部2からの新鮮な外気の供給も停止する。高気密住居では空調と換気とを切り離して快適な環境を形成することはできない。この実施例1の換気空調装置では、室内温度を設定温度に維持するのになるべく空調用送風機8,9を停止させないように制御し、空調用送風機8,9の停止時間が短いので換気部2からの新鮮な外気の供給が停止する時間も短くなり、換気と空調とが調和的ないしは協調的に行なわれ快適な換気空調環境を形成することができる。 (4) While the air conditioners 8 and 9 are stopped, the supply of fresh outside air from the ventilation unit 2 to the zone B or the zone C connected to the air conditioner 7 is also stopped. In a highly airtight house, a comfortable environment cannot be formed by separating air conditioning and ventilation. In the ventilating air-conditioning apparatus according to the first embodiment, the air-conditioning blowers 8, 9 are controlled so as not to stop as much as possible to maintain the room temperature at the set temperature. Also, the time during which the supply of fresh outside air is stopped is shortened, and ventilation and air conditioning are performed harmoniously or cooperatively, so that a comfortable ventilation and air conditioning environment can be formed.

 実施例2.この実施例2は上記した実施例1で示したものの制御装置18により暖房用熱源発生機16及び冷房用熱源発生機17の熱源の流量をも制御するようにしたもので、装置本体1の構成及び制御装置18の一部の構成は実施例1に示したものと同じである。従って、実施例1と同一部分についてはそれらにかかる図を援用するとともに、同一の符号を用いそれらの説明を省略する。 {Example 2}. The second embodiment is different from the first embodiment in that the controller 18 also controls the flow rates of the heat sources of the heating heat source generator 16 and the cooling heat source generator 17. The configuration of a part of the control device 18 is the same as that shown in the first embodiment. Therefore, the same parts as those in the first embodiment will be referred to the drawings relating thereto, and the same reference numerals will be used, and the description thereof will be omitted.

 この実施例2の制御装置18は、上述の実施例1によって示した制御機能の他に暖房用熱源発生機16及び冷房用熱源発生機17に対して、それらの熱源の供給流量を風量に関連付けて制御する制御機能を備えている。冷暖房能力は、空調用送風機8,9による送風量によっても変化させ得るが、熱源の流量を変化させるだけでも、或いは送風量と熱源の流量を共に変化させても変えることができる。図8は例えば暖房において温水等の熱源の流量と空調用送風機8,9の風量とを変化させた時の暖房能力の変化を示したものである。この図8においても分るように、例えば風量が強ノッチの大風量で、流量が4l/minの時の暖房能力と風量が中ノッチの中風量で流量が12l/minの時の暖房能力はほぼ同等である。 The control device 18 according to the second embodiment associates the supply flow rate of the heat source with the air flow rate with respect to the heating heat source generator 16 and the cooling heat source generator 17 in addition to the control function described in the first embodiment. It has a control function to control The cooling and heating capacity can be changed by changing the air flow rate of the air-conditioning blowers 8, 9, but can also be changed by simply changing the flow rate of the heat source or changing both the flow rate and the flow rate of the heat source. FIG. 8 shows a change in the heating capacity when, for example, the flow rate of a heat source such as hot water and the air flow rates of the air conditioners 8 and 9 are changed in heating. As can be seen from FIG. 8, for example, the heating capacity when the air volume is a large air volume with a strong notch and the flow rate is 4 l / min, and the heating capacity when the air volume is a medium air volume with a middle notch and the flow rate is 12 l / min are as follows. Almost equivalent.

 即ち、必要とする冷暖房能力を得るのに、流量を制御して風量の少ない状態で空調用送風機8,9を運転させる。例えば図9に示すように調節信号Cを1〜10までの10段階に分け、各段階の調節信号Cに空調用送風機8,9のノッチと熱源の流量の指令値を振り分け、制御装置18からの調節信号Cにより空調用送風機8,9と暖房用熱源発生機16又は冷房用熱源発生機17とを制御する。この時、制御装置18は図10に示すように各ゾーンB,Cに対する調節信号Cの大小を比較し、そのうちの最も大きい熱源流量で暖房用熱源発生機16又は冷房用熱源発生機17を制御する。これにより冷暖房能力をリニアに変化させることができ、騒音の発生を押さえながら、なるべく空調用送風機8,9を停止させないように制御して室内温度を設定温度になるようにすることができる。これ以外の機能及び効果は実施例1のものと同じであるのでその説明は省略する。 That is, in order to obtain the required cooling and heating capacity, the air-conditioning blowers 8 and 9 are operated in a state where the air flow is small by controlling the flow rate. For example, as shown in FIG. 9, the control signal C is divided into 10 stages from 1 to 10, and the notch of the air-conditioning blowers 8, 9 and the command value of the flow rate of the heat source are distributed to the control signal C of each stage. The air conditioning blowers 8 and 9 and the heating heat source generator 16 or the cooling heat source generator 17 are controlled by the adjustment signal C of (1). At this time, the controller 18 compares the magnitudes of the adjustment signals C for the zones B and C as shown in FIG. 10, and controls the heating heat source generator 16 or the cooling heat source generator 17 with the largest heat source flow rate. I do. As a result, the cooling / heating capacity can be changed linearly, and the room temperature can be set to the set temperature by controlling the air-conditioning blowers 8, 9 as much as possible while suppressing the generation of noise. The other functions and effects are the same as those of the first embodiment, and the description thereof will be omitted.

 実施例3.この実施例3は上記した実施例1で示した装置本体1の給気用送風機5と排気用送風機4とを風量可変のものとし、装置本体1に組込んだ制御装置18によって給気用送風機5と排気用送風機4の風量も制御するようにしたものである。この他の装置本体1の構成及び制御装置18の一部の構成は実施例1に示したものと同じである。従って、実施例1と同一部分についてはそれらにかかる図を援用するとともに、同一の符号を用いそれらの説明を省略する。 {Example 3}. In the third embodiment, the air supply blower 5 and the exhaust blower 4 of the apparatus main body 1 shown in the above-described first embodiment have variable airflow, and the air supply blower is controlled by a control device 18 incorporated in the apparatus main body 1. 5 and the air volume of the exhaust blower 4 are also controlled. Other configurations of the apparatus main body 1 and a part of the configuration of the control device 18 are the same as those shown in the first embodiment. Therefore, the same parts as those in the first embodiment will be referred to the drawings relating thereto, and the same reference numerals will be used, and the description thereof will be omitted.

 この実施例3の制御装置18は、上述の実施例1によって示した制御機能の他に、図11に示すように各ゾーンB,Cからの冷房運転又は暖房運転の要求が何箇所から出ているかをマイクロコンピュータ23で確認し、各ゾーンB,Cに対応した運転動作を空調部3に行なわせる。このとき、冷房運転又は暖房運転の要求の箇所が全箇所であれば、給気用送風機5と排気用送風機4を強ノッチで運転させ、一ゾーンB又はCだけの運転要求であれば給気用送風機5と排気用送風機4を弱ノッチで運転させる。 In addition to the control functions shown in the above-described first embodiment, the control device 18 according to the third embodiment receives a request for a cooling operation or a heating operation from each zone B and C from several places as shown in FIG. The microcomputer 23 checks whether or not the air conditioner 3 is in operation, and causes the air conditioner 3 to perform an operation corresponding to each of the zones B and C. At this time, if all the places of the request of the cooling operation or the heating operation are required, the air supply blower 5 and the exhaust blower 4 are operated at the strong notch, and if the operation request is only for one zone B or C, the air supply is performed. The air blower 5 and the exhaust blower 4 are operated with a weak notch.

 一般に高気密な空間で必要な常時換気量は、一人当り20〜30m/hとされていて、設定した条件でこれを満たすに足る換気量が得られるようにこの換気空調装置の換気能力も設定されている。従って、使用しているゾーンB,Cが僅かな時に能力全部による換気を行なえば、過剰換気になるばかりでなく冷暖房負荷も増大する。また、使用しているゾーンB,Cが多いのに能力の一部による換気を行なえば、冷暖房負荷は低減するものの換気不足になり、換気環境は悪化する。この種の装置ではこれまで換気量に関する調節は使用者の思惟に委ねられてきたが、高気密住宅では換気量の調節を思惟的なものとすると、換気不足による事故の危険もあるので改善しなければならない。この点、この実施例3による換気空調装置では換気量が必要に応じて自動調節され、高気密住宅の適正換気が図12に示すように省エネルギーを図りつつ実現し、換気部2の騒音も低減する。これ以外の機能は基本的には実施例1のものと同じであるのでそれらについての説明は省略する。 Generally, the constant ventilation required in a highly airtight space is set to 20 to 30 m 3 / h per person, and the ventilation capacity of the ventilation air conditioner is set so that sufficient ventilation can be obtained under the set conditions. Is set. Therefore, if the zones B and C in use are slightly ventilated when the capacity is full, not only excessive ventilation is performed but also the cooling / heating load is increased. In addition, if ventilation is performed with a part of the capacity even though many zones B and C are used, the cooling / heating load is reduced, but the ventilation is insufficient and the ventilation environment is deteriorated. In this type of equipment, the adjustment of the ventilation rate has been left to the user's thinking.However, if the adjustment of the ventilation rate is thoughtful in a highly airtight house, there is a danger of an accident due to insufficient ventilation. There must be. In this regard, in the ventilation air-conditioning apparatus according to the third embodiment, the ventilation amount is automatically adjusted as necessary, and proper ventilation of a highly airtight house is realized while saving energy as shown in FIG. 12, and the noise of the ventilation unit 2 is also reduced. I do. Other functions are basically the same as those of the first embodiment, and the description thereof will be omitted.

 実施例4.この実施例4は上記した実施例3で示した換気空調装置に除湿運転機能を付加し、図13と図14に示すように制御装置18のマイクロコンピュータ23により除湿運転の指令があった時には強制的に冷房用熱源発生機17を運転させ、指令のあった当該ゾーンB,Cに対応する空調用送風機8,9を弱ノッチで運転させ、同時に換気部2の給気用送風機5と排気用送風機4を弱ノッチで運転させるようにしたものである。この他の装置本体1の構成及び制御装置18の構成は実施例3に示したものと同じである。従って、実施例3と同一部分についてはそれらにかかる図を援用するとともに、同一の符号を用いそれらの説明を省略する。 Embodiment 4 In the fourth embodiment, a dehumidifying operation function is added to the ventilating air-conditioning system shown in the third embodiment, and when a dehumidifying operation command is issued by the microcomputer 23 of the controller 18 as shown in FIGS. The cooling heat source generator 17 is operated in a specific manner, and the air-conditioning blowers 8, 9 corresponding to the zones B, C in which the commands have been issued are operated with a weak notch, and at the same time, the air supply blower 5 and the exhaust The blower 4 is operated with a weak notch. Other configurations of the apparatus main body 1 and the configuration of the control device 18 are the same as those shown in the third embodiment. Therefore, the same parts as those in the third embodiment will be referred to the drawings relating thereto, and the same reference numerals will be used, and the description thereof will be omitted.

この実施例4の制御装置18をもつ換気空調装置によれば、除湿運転にあたっては換気量が一時的に押さえられるので換気とともに各ゾーンA,B,Cへ供給される湿気も少なくなり除湿機能が向上し、高気密住宅での除湿が効果的に行なわれることになる。これ以外の機能は実施例3のものと同じであるのでそれらについての説明は省略する。 According to the ventilating air-conditioning apparatus having the control device 18 of the fourth embodiment, the amount of ventilation is temporarily suppressed during the dehumidifying operation, so that the humidity supplied to each of the zones A, B and C together with the ventilation is reduced, and the dehumidifying function is improved. It will improve the efficiency of dehumidification in airtight houses. The other functions are the same as those of the third embodiment, and the description thereof will be omitted.
