(3) fan energy-output ratio along with the feed air temperature (air feed air quantity) of air conditioner and outdoor air conditioner machine change and increase and decrease;
But, in the past, designed air conditioner, outdoor air conditioner machine etc. when not considering these, and carried out operation control, therefore faced the situation that energy consumption bootlessly increases.
Summary of the invention
One aspect of the present invention, in order to solve the problem, a kind of outdoor air conditioner machine with air conditioning function is provided, possess: to be arranged in ceiling or indoor a part on enclosure space import from the extraneous air outside room and from described indoor return-air and mix, regulate the air quantity adjusting mechanism of the blending ratio of described extraneous air and described return-air simultaneously; Be arranged in described enclosure space, there is the air intake described extraneous air in described enclosure space and described return-air taken in as idle call air, the cabinet be simultaneously connected communicatively with supply conduit; Be arranged in described cabinet, the heat exchanger coil that described idle call air passes through; Be arranged in described cabinet, make described idle call air by described heat exchanger coil and from described supply conduit to the fan of described indoor air-supply; The steam-type humidifier of the steam of humidification is released to described idle call air; With the described air quantity adjusting mechanism of operation, control the blending ratio of described extraneous air and described return-air, the setting concentration preset to make the gas concentration lwevel of described indoor reach, thus carbon dioxide control part.
According to the present invention:
(1) make enclosure space with dividing plate etc. in ceiling or in a part for indoor and be provided with the outdoor air conditioner machine of air conditioning function, the not connecting duct of air requirement governor motion and cabinet, therefore easily constructs, the reduction of erection time, seeks to reduce costs.Owing to being that air takes in room by enclosure space dual-purpose, therefore not needing the component of air-supply conduit, seek to reduce costs;
(2) conduit only needs air feed conduit, and the barrier therefore around cabinet is few, thus easily maintains, and do not have extra air-supply conduit, the pressure loss also can diminish correspondingly, therefore energy-conservation;
(3) in enclosure space, mix extraneous air and return-air, so there is no mixing uneven, uniform heat exchange can be realized, owing to being steam humidification, therefore seek the precision improving indoor Temperature and Humidity Control;
(4) due to be mixing extraneous air and return-air carry out heat exchange, therefore when the air conditioner loads such as spring and autumn are few, extraneous air process and return-air process can be carried out separately with the outdoor air conditioner machine with air conditioning function, and stopping or off and on operating band have the air conditioner beyond the outdoor air conditioner machine of air conditioning function, therefore energy-conservation;
(5) above-mentioned outdoor air conditioner machine is multi-functional, can carry out that cooling runs, heating runs, air-supply runs, complete outer air cooling but runs, winter cools and low-temperature humidifying, thus can tackle air conditioning requirements widely;
(6), when extraneous air load is large, gas concentration lwevel (CO is caused because of occupancy minimizing etc.
2concentration) when reducing, reduce extraneous air amount by carbon dioxide control part, thus seek to reduce air conditioner energy source consumption.
On the other hand, the outdoor air conditioner facility with air conditioning function of the present invention are standby: using from the extraneous air outside room and the cabinet that imports as idle call air from the return-air of indoor; Be arranged in described cabinet, for the heat exchanger coil that the heat exchange water cooled or heat described idle call air flows through; Be arranged in described cabinet, make described idle call air by described heat exchanger coil and to the fan of described indoor air-supply; Regulate the air quantity adjusting mechanism of the blending ratio of described extraneous air and described return-air; Regulate the runoff investigation mechanism of the flow of described heat exchange water; And control device; Described heat exchanger coil has the entrance and exit of described heat exchange water; Described control device possesses: operate described air quantity adjusting mechanism, control the blending ratio of described extraneous air and described return-air with the carbon dioxide control part of the setting concentration making the gas concentration lwevel of described indoor reach to preset; With the described runoff investigation mechanism of operation, control the flow of described heat exchange water, to make as reaching by the feed air temperature of the temperature of the described idle call air of described heat exchanger coil the setting feed air temperature preset, operate described runoff investigation mechanism simultaneously, control the flow of described heat exchange water, reach the water rate control portion of the set water temperature degree difference preset using the coolant-temperature gage difference of the difference making the temperature of the described heat exchange water as the temperature of the described heat exchange water of described entrance and described outlet.According to this invention, all right:
(1) in carbon dioxide control part, when extraneous air load is large, when causing gas concentration lwevel to reduce because of occupancy minimizing etc., extraneous air amount can be reduced, seek the consumption reducing air conditioner energy source;
(2) even if air conditioner load changes, also the temperature for making idle call air is controlled, setting value is reached together with the coolant-temperature gage difference of the difference of the temperature of the heat exchange water of its entrance with the temperature of the heat exchange water of the outlet as heat exchanger coil, therefore under the air conditions (being not merely the condition within doors or outside room of planning) of wide scope, carry out the reduction of the fan energy-output ratio of the few air quantity by idle call air simultaneously, by the reduction of the conveying pump energy-output ratio of few water yield of heat exchange water (cold water or warm water), by improving the reduction of the heat source machine energy-output ratio of above-mentioned coolant-temperature gage difference, thus seek significantly energy-conservation,
Such as, the heat energy had by the cooling of heat exchanger coil or the idle call air of heating is the difference (namely enthalpy is poor) of enthalpy of the enthalpy of the air of heat exchanger coil entrance and the air of heat exchanger coil outlet and the product of the air quantity by the idle call air of heat exchanger coil, and when therefore heat energy is constant, the larger air quantity to indoor conveying of enthalpy difference is fewer;
Therefore, if the above-mentioned enthalpy improving heat exchanger coil is poor, namely reducing setting feed air temperature when cooling idle call air, improving setting feed air temperature when heating idle call air, then can cut down the energy consumption of fan;
Again, the flow of the heat exchange water of heat exchanger coil and the product of the coolant-temperature gage difference of the difference of the temperature as the temperature of the heat exchange water of the outlet of heat exchanger coil and the heat exchange water of entrance by the heat exchange amount (through-flow heat) of the heat exchange water of heat exchanger coil, therefore when the through-flow heat of heat exchanger coil is constant, along with above-mentioned coolant-temperature gage difference increases, the amount of the heat exchange water circulated between heat source machine and the outdoor air conditioner machine with air conditioning function reduces.Therefore, the energy-output ratio of the conveying pump of heat exchange water can be cut down when improving above-mentioned coolant-temperature gage difference;
In addition, during the heat exchange water of the outlet of heat source machine temperature-resistant, along with the above-mentioned coolant-temperature gage difference on heat exchanger coil increases, when cooling runs, average cold water temperature rises, when heating runs, average warm water temperature declines, and therefore can cut down the energy-output ratio of heat source machine;
(3) only can control the flow of coolant-temperature gage difference and heat exchange water with the outdoor air conditioner machine with air conditioning function, and not need to carry out the control except with the heat source machine except the outdoor air conditioner machine of air conditioning function etc., thus seek the simplification of equipment;
(4) seek with in the past equal ability under significantly cut down energy-output ratio, comfortableness and energy saving two aspects can be realized simultaneously.
The outdoor air conditioner machine with air conditioning function of the present invention can also be made, be under the pattern cooling described idle call air at described heat exchanger coil, be configured such that the temperature of the described heat exchange water of described entrance is 10 ~ 12 DEG C, make described coolant-temperature gage difference be 8 ~ 12 DEG C, make described feed air temperature be 12 ~ 14 DEG C; Meanwhile, be under the pattern heating described idle call air at described heat exchanger coil, be configured such that the temperature of the described heat exchange water of described entrance is 35 ~ 40 DEG C, make described coolant-temperature gage difference be 8 ~ 12 DEG C, make described feed air temperature be 30 ~ 35 DEG C.According to such invention, all right:
(1) when the heat source machine of heat-pump-type cold etc. runs for cooling, cold water outlet temperature uprises, then energy-output ratio can reduce, warm water outlet temperature step-down when heating runs, then energy-output ratio can reduce;
Therefore, the design temperature (design temperature of the heat exchange water of the outlet of heat source machine) of the heat exchange water of the entrance of heat exchanger coil during idle call Air flow is 10 ~ 12 DEG C (being always 7 DEG C), the temperature of the heat exchange water of the entrance of heat exchanger coil during idle call Air flow is, because the hot-fluid of the heat exchanger coil by bypass air etc. to need the cold water of low more than 3 DEG C than feed air temperature through the reason of the upper limit of ability, therefore in order to the reduction of the energy-output ratio of heat source machine, be set as 10 DEG C best;
The design temperature of the heat exchange water of the entrance of heat exchanger coil during idle call air heat is preferably 35 ~ 40 DEG C (being always 45 DEG C), but, the temperature of the heat exchange water of the entrance of heat exchanger coil during idle call air heat is, reason due to the upper limit of the hot through-flow ability of heat exchanger coil needs the warm water of higher than feed air temperature more than 3 DEG C, therefore in order to the reduction of the energy-output ratio of heat source machine, be set as 40 DEG C best;
Again, setting feed air temperature during idle call Air flow, if when considering to remove indoor from the latent heat that human body etc. produces, also be preferably 12 ~ 14 DEG C (always 16 DEG C), but in order to cut down fan energy-output ratio, bottom line suppresses condensation and the coldblast of indoor blow-off outlet, is be set as 13 DEG C best;
Setting feed air temperature during idle call air heat is preferably 30 ~ 35 DEG C (being always 28 DEG C), if but when considering that heat source machine energy-output ratio can reduce this aspect when the temperature of the heat exchange water of the entrance of heat exchanger coil and the difference of feed air temperature reduce, be set as 30 DEG C best;
The coolant-temperature gage difference (set water temperature degree is poor) of the design temperature of the design temperature of the heat exchange water of the entrance of heat exchanger coil and the heat exchange water of outlet, be preferably 8 ~ 12 DEG C (being always 5 DEG C) to cut down the energy-output ratio of conveying pump and heat source machine, but be set as 10 DEG C best due to the reason of coolant-temperature gage difference that can tackle with general heat source machine.
Also the described control device of outdoor air conditioner machine of the present invention can be made to possess: when the temperature of described extraneous air reaches described setting feed air temperature, operate described runoff investigation mechanism and stop described heat exchange water to flow in described heat exchanger coil, operate described air quantity adjusting mechanism simultaneously and make the air blowing control portion that described idle call air is all made up of described extraneous air; When the temperature of described extraneous air exceedes described setting feed air temperature and extraneous air enthalpy is less than return-air enthalpy, operate described air quantity adjusting mechanism to be all made up of described extraneous air to make described idle call air, operate described runoff investigation mechanism to control the flow of described heat exchange water simultaneously, thus make described feed air temperature reach the full extraneous air cooling control part of described setting feed air temperature; And, when the temperature of described extraneous air is less than described setting feed air temperature and the temperature of described return-air exceeds the setting suction temperature preset, operates described air quantity adjusting mechanism, control the ratio of the described return-air in described idle call air and cool control part with the winter making described feed air temperature and reach described setting feed air temperature.According to such invention, all right:
(1) in air blowing control portion, owing to not making extraneous air heat exchange can carry out air conditioning by means of only to indoor air-supply, the energy-output ratio of heat source machine can therefore be cut down, thus energy-conservation;
(2) in full extraneous air cooling control part, owing to only cooling the enthalpy extraneous air lower than room air and carrying out air conditioning, therefore with cooling return-air or cool extraneous air and compare with the mixing air of return-air the energy-output ratio more cutting down heat source machine, thus energy-conservation;
(3) cool in the winter time in control part, in the extraneous air of low temperature, the return-air of high temperature is mixed to be adjusted to setting feed air temperature and to carry out air conditioning with air quantity adjusting mechanism in the winter time during indoor heating, and do not make extraneous air heat exchange, therefore the energy-output ratio of heat source machine can be cut down, thus energy-conservation.In addition, the four tubular type pipe arrangements that can simultaneously make the cooling cold water of idle call air and reheating warm water flow through are not needed;
(4) above-mentioned outdoor air conditioner machine is multi-functional, can carry out cooling operation, heating runs, air-supply operation, entirely outer air cooling but run and cooling in winter runs, thus can tackle air conditioning requirements widely;
(5) during air quantity adjusting mechanism can be common to carbon dioxide control, air-supply runs, extraneous air cooling operation and cooling in winter run entirely, thus seek to reduce costs.
Outdoor air conditioner machine with air conditioning function of the present invention, also can possess: the variable air rate mechanism regulating the air quantity being delivered to the described idle call air of described indoor by described fan; And described control device possesses when the temperature of described return-air is less than the setting suction temperature preset, operate described variable air rate mechanism to control the air quantity of described idle call air, thus the supercooling making the temperature of described return-air reach described setting suction temperature prevents control part.According to the outdoor air conditioner machine of this invention, all right:
(1) when the little grade of air conditioner load, indoor suction temperature excessive descent compared with setting suction temperature can be prevented by reducing air feed air quantity, thus improve comfortableness.
Again, the outdoor air conditioner machine with air conditioning function of the present invention, also can possess the steam-type humidifier of the steam of releasing humidification to described idle call air; And described control device possesses when return-air absolute humidity is less than the setting return-air absolute humidity preset, control the steam discharging volume of described steam-type humidifier, thus make described return-air absolute humidity not exceed the humidification control part of the upper limit of the absolute humidity of described idle call air.According to this invention, all right:
(1) even if carry out humidification while also can preventing condensation when the situation of idle call air low temperature and evaporation absorption distance short (in air-flow by the moisture of spraying until absorb by air required moisture displacement), do not need the remover etc. removing dew, can seek to reduce costs and densification;
(2) due to return-air absolute humidity humidification, high-precision indoor temperature and humidity can be realized and control.
In addition, the heat-transfer pipe (15) of described heat exchanger coil of the present invention can be made to be made up of elliptical tube, according to such invention, all right:
(1) owing to being elliptical tube, the pressure loss is little, therefore by increasing the columns (hot through-flow amount) of heat exchanger coil, the design temperature (design temperature of the heat exchange water of the outlet of heat source machine) of the heat exchange water of the entrance of heat exchanger coil is made to increase when cooling, making it decline when heating, the energy-output ratio (not increasing the energy-output ratio of fan) of heat source machine can be reduced with this;
In addition, increased the ventilation section area of heat exchanger coil by wind speed by reduction heat exchanger coil, maintain air feed air quantity and cooling or heating efficiency, change the stream method (changing the structure in the loop of the heat exchange water in coil pipe) of the heat exchange water in coil pipe simultaneously, make to send water apart from elongated with this, anti-sealing prompt drop is low, prevent the minimizing (ability reduction) of the through-flow heat occurred along with water prompt drop is low, above-mentioned coolant-temperature gage can be improved poor, reduce the energy-output ratio of conveying pump and heat source machine;
In addition, when the heat-transfer pipe of heat exchanger coil is pipe, in order to become the energy-output ratio that can increase considerably fan when above-mentioned design temperature increases the columns of coil pipe, not energy-conservation.

Detailed description of the invention
Fig. 1 and Fig. 2 is the embodiment that the outdoor air conditioner machine with air conditioning function of the present invention is shown, should with the outdoor air conditioner facility standby host case 1 of air conditioning function, steam-type humidifier 2, air quantity adjusting mechanism D, runoff investigation mechanism V and control device 3.Arrange in enclosure space CS in a part of the inner S of ceiling 34 of building and regulate as the air quantity adjusting mechanism D of idle call air from the extraneous air outside room and the blending ratio from the return-air of indoor, and enclosure space is used as easy Machine Room, transversely long cabinet 1 is set therein.The wall portion forming enclosure space and ceiling arrange extraneous air air door 4 and the return-air air door 5 of the proportion expression regulating air quantity, thus forms air quantity adjusting mechanism D.In legend, enclosure space CS is made up of wall portion 32, floor section 33, ceiling 34, partition wall portion 35, but its formation can freely change.
Cabinet 1 has the air intake 6 extraneous gas in enclosure space and return air taken in as idle call air and the air outlet slit 7 be communicated with air intake 6.Air outlet slit 7 is connected communicatively with supply conduit 8.Arrange in cabinet 1 flow through for the heat exchange water cooled or heat idle call air heat exchanger coil 9, make idle call air through heat exchanger coil 9 and by supply conduit 8 to the fan 10 of indoor air-supply, the humidification nozzle 11 of releasing the steam-type humidifier 2 of the steam of humidification to the idle call air through heat exchanger coil 9, filter 12 and drip tray 13.
Fan 10 arranges the variable air rate mechanism E be made up of converter of the air feed air quantity regulating idle call air.In addition, freely can change to known electric pole type and the various pattern such as electrothermal, steam spray formula as steam-type humidifier 2, or select the humidifier of gasifying type.In legend, illustrate the situation only configuring humidification nozzle 11 in cabinet 1, but also the apparatus of the steam generator supplying steam to humidification nozzle 11 etc. can be set in cabinet 1.
The solid line of legend and the hollow arrow of dotted line are that air supply direction is shown, the idle call air utilizing fan 10 to suck is through heat exchanger coil 9 and by supply conduit 8 and omit illustrated blow-off outlet to indoor air feed.Heat exchanger coil 9 multiple heat transfer plates 14 of arranging freely insert multiple heat-transfer pipe 15 and is formed ventilating, and the air flowing through heat exchange water (cold water or warm water) in heat-transfer pipe 15 and process carries out heat exchange by heat-transfer pipe 15 and heat transfer plate 14.This heat-transfer pipe 15 is better with elliptical tube, is round tube alternatively.Heat exchange on heat exchanger coil 9 entrance of water and outlet are connected and the water regulating valve 17 of Set scale formula with cold water pipe arrangement or hot water pipe 16 pipeline, thus form the runoff investigation mechanism V of the flow of the water regulating heat exchanger coil 9.Heat exchanger coil 9 is connected with the illustrated heat source machine of omission and conveying pump by pipe arrangement 16, and the heat exchange water (cold water or warm water) being adjusted to set point of temperature with this heat source machine circulates in heat exchanger coil 9 and described heat source machine.In addition, pipe arrangement 16 double hose flow through of freely can selecting that cold water and warm water are switched, cold water and warm water are flow through simultaneously four tubular types in any one.
Control device 3 possesses the extraneous air Temperature and Humidity device 18 detecting extraneous air humiture, detect the temperature of return-air and the return air temperature moisture detector 19 of humidity, detect by the temperature of the idle call air (i.e. air feed) of heat exchanger coil 9 and the air feed Temperature and Humidity device 31 of humidity, detect the coolant-temperature gage difference detector 20 of the coolant-temperature gage difference of the difference of the temperature as the temperature of the heat exchange water of the entrance of heat exchanger coil 9 and the heat exchange water of outlet, detect the carbon dioxide indicator 21 of the gas concentration lwevel of return-air (indoor), carbon dioxide control part 22, water rate control portion 23, air blowing control portion 24, full extraneous air cooling control part 25, cool control part 26 winter, supercooling prevents control part 27, humidification control part 28, configuration part 29, mode decision portion 30, and by sensor, actuator, the formations such as microcomputer.
Fig. 3 is the flow chart of cold water mode operation, and Fig. 4 is the flow chart of warm water mode operation, and Fig. 5 is the flow chart of mode decision process.Carbon dioxide control part 22 controls idle call air blending ratio by air quantity adjusting mechanism D reaches setting concentration to make the gas concentration lwevel of the indoor detected via carbon dioxide indicator 21.Such as, when causing gas concentration lwevel because of the increase and decrease etc. of occupancy lower than setting concentration, control the extraneous air ratio for idle call air can be reduced by return-air air door 5 and extraneous air air door 4 and improve gas concentration lwevel, when gas concentration lwevel is higher than setting concentration, controls the extraneous air ratio for idle call air can be increased by return-air air door 5 and extraneous air air door 4 and reduce gas concentration lwevel.
The flow that water rate control portion 23 water consumption governor motion V controls water reaches setting feed air temperature to make the feed air temperature of the temperature as the idle call air (air feed) by heat exchanger coil detected by air feed Temperature and Humidity device 31, and the flow controlling water with hourly water consumption governor motion V is poor to make the coolant-temperature gage difference detected by coolant-temperature gage difference detector 20 reach set water temperature degree.Such as, control when cooling and running to be that, when feed air temperature is lower than setting feed air temperature, water consumption control valve 17 reduces the flow of water to improve feed air temperature, when feed air temperature is higher than setting feed air temperature, water consumption control valve 17 increases the flow of heat exchange water to reduce feed air temperature.Be made as when feed air temperature reaches the time control of setting feed air temperature, being less than set water temperature degree difference hourly water consumption control valve 17 in coolant-temperature gage difference, to reduce the flow of heat exchange water poor to improve coolant-temperature gage, and coolant-temperature gage is poor, and to be greater than the flow that the poor hourly water consumption control valve 17 of set water temperature degree increases heat exchange water poor to reduce coolant-temperature gage.Again, when heating operation, control is, when feed air temperature is lower than setting feed air temperature, water consumption control valve 17 increases the flow of heat exchange water to improve feed air temperature, when feed air temperature is higher than setting feed air temperature, water consumption control valve 17 reduces the flow of heat exchange water to reduce feed air temperature.Be made as when feed air temperature reaches the time control of setting feed air temperature, being less than set water temperature degree difference hourly water consumption control valve 17 in coolant-temperature gage difference, to reduce the flow of heat exchange water poor to improve coolant-temperature gage, and coolant-temperature gage is poor, and to be greater than the flow that the poor hourly water consumption control valve 17 of set water temperature degree increases heat exchange water poor to reduce coolant-temperature gage.By means of this, control together to reach setting value for making as the feed air temperature of the temperature of the idle call air by heat exchanger coil and above-mentioned coolant-temperature gage difference.
Above-mentioned setting value is when cooling idle call air with heat exchanger coil 9, the temperature of the heat exchange water on the entrance of heat exchanger coil 9 is set as 10 ~ 12 DEG C (being preferably 10 DEG C), coolant-temperature gage difference on heat exchanger coil 9 is set as 8 ~ 12 DEG C (being preferably 10 DEG C), the temperature (feed air temperature) of the idle call air by heat exchanger coil is set as 12 ~ 14 DEG C (being preferably 13 DEG C), simultaneously when heating idle call air with heat exchanger coil 9, the temperature of the heat exchange water on the entrance of heat exchanger coil 9 is set as 35 ~ 40 DEG C (being preferably 40 DEG C), coolant-temperature gage difference on heat exchanger coil 9 is set as 8 ~ 12 DEG C (being preferably 10 DEG C), the temperature (feed air temperature) of the idle call air by heat exchanger coil is set as 30 ~ 35 DEG C (being preferably 30 DEG C).
When air blowing control portion 24 being controlled for reaching at the external air temperature detected with extraneous air Temperature and Humidity device 18 the setting feed air temperature preset, operation runoff investigation mechanism V, heat exchange use water is stopped to flow in heat exchanger coil 9, operate air quantity adjusting mechanism D simultaneously, idle call air is all formed with extraneous air.Such as, when air conditioner load is little, when feed air temperature reaches setting feed air temperature, the extraneous air rate control of idle call air by the flow vanishing of heat exchange water, and is 100% by return-air air door 5 and extraneous air air door 4 by water consumption control valve 17.The extraneous air refrigeration in Here it is so-called summer.
Full extraneous air cooling control part 25 exceedes setting feed air temperature at the external air temperature detected with extraneous air Temperature and Humidity device 18, and the extraneous air enthalpy outside room is when being less than indoor return-air enthalpy, operation air quantity adjusting mechanism D, idle call air is all made up of extraneous air, operate runoff investigation mechanism V simultaneously, to control the flow of heat exchange water, feed air temperature is made to reach setting feed air temperature.Such as, when the external air temperature in summer is lower than indoor suction temperature and higher than setting feed air temperature, by return-air air door 5 and extraneous air air door 4, the extraneous air ratio of the air of idle call is become 100%, and water consumption control valve 17 controls the flow of heat exchange water, feed air temperature is made to reach setting feed air temperature.Described extraneous air enthalpy is calculated by the temperature of the extraneous air detected by extraneous air Temperature and Humidity device 18 and humidity, and above-mentioned return-air enthalpy is calculated by the temperature of the return-air detected by return air temperature moisture detector 19 and humidity.
Cooling control part 26 winter is exceed setting suction temperature at the suction temperature detected with return air temperature moisture detector 19, and be less than setting feed air temperature with the external air temperature that extraneous air Temperature and Humidity device 18 detects, when the gas concentration lwevel of the indoor detected with carbon dioxide indicator 21 is less than setting concentration, water consumption governor motion V stops heat exchange use water to flow in heat exchanger coil 9, operate air quantity adjusting mechanism D simultaneously, to control the return-air ratio of idle call air, the feed air temperature detected by air feed Temperature and Humidity device 30 is made to reach setting feed air temperature.Such as, indoor suction temperature exceedes setting suction temperature in the winter time, when external air temperature is lower than setting feed air temperature, operation water regulating valve 17, make the flow vanishing of heat exchange water, the return-air ratio being increased idle call air by return-air air door 5 and extraneous air air door 4 improves temperature, controls as making feed air temperature reach setting feed air temperature.Setting concentration is reached at gas concentration lwevel return-air ratio being increased to the indoor detected with carbon dioxide indicator 21, when feed air temperature is also less than setting feed air temperature, with the warm water heating idle call air of heat exchanger coil 9, it is made to reach setting feed air temperature to control feed air temperature.
Supercooling prevent control part 27 be when the suction temperature detected with return air temperature moisture detector 19 be less than setting suction temperature, with the gas concentration lwevel of indoor that carbon dioxide indicator 21 detects be less than set concentration, control air feed air quantity with variable air rate mechanism E, thus make suction temperature reach setting suction temperature.Such as, in the operation of various pattern, when indoor suction temperature is less than setting suction temperature, water consumption control valve 17 makes the flow of heat exchange water minimum, and reduce the air feed air quantity of fan 10 to improve suction temperature by variable air rate mechanism E, control to make it reach setting suction temperature.
Humidification control part 28 be when the return-air absolute humidity of the indoor detected with return air temperature moisture detector 19 be less than the return-air preset absolute humidity, namely set return-air absolute humidity, control the steam burst size of steam-type humidifier 2, with the upper limit making return-air absolute humidity not exceed the absolute humidity of idle call air (air feed).Such as, when the setting return-air absolute humidity of indoor is below the upper limit of the absolute humidity of air feed, control is, to set return-air absolute temperature as target steam-type humidifier 2 humidification, when the setting return-air absolute humidity of indoor exceedes the upper limit of the absolute humidity of air feed, carry out humidification using the upper limit of the absolute humidity of air feed as target.The upper limit of the absolute humidity of air feed is, when the temperature of air feed becomes saturated moist air and absolute humidity before condense (condensation) for this air feed during setting feed air temperature, and the value be set by calculating grade.
Configuration part 29 sets that set water temperature degree in the setting feed air temperature of idle call air (air feed), indoor setting suction temperature, indoor setting return-air absolute humidity, the setting concentration of indoor carbon dioxide, heat exchanger coil 9 is poor, the upper limit of the absolute humidity of air feed respectively.These setting values can be single numerical value, also can be the numerical value of the prescribed limit comprising threshold value, can unrestricted choice.
As shown in Figure 5, mode decision portion 30 is when cold water flows through pipe arrangement 16, for during setting feed air temperature, external air temperature is judged as that air-supply runs, external air temperature exceedes setting feed air temperature, and when extraneous air enthalpy is less than indoor return-air enthalpy outside room, be judged as that the cooling of full extraneous air runs, extraneous air exceedes setting feed air temperature, and suction temperature runs for when more than setting suction temperature is judged as cooling.Again, when warm water flows through pipe arrangement 16, for during setting feed air temperature, external air temperature is judged as that air-supply runs, external air temperature is less than setting feed air temperature, and suction temperature exceed setting suction temperature time be judged as winter cooling run, external air temperature is less than setting feed air temperature, and is judged as that heating runs when suction temperature is less than setting suction temperature.
Fig. 3 is an example of cold water mode operation, when bringing into operation, makes the heat exchange water (cold water) of the regulation water yield flow through heat exchanger coil 9, and makes the extraneous air ratio of idle call air become 100% and to indoor with certain air quantity air feed.Then, when blowing operation, stopping heat exchange water (cold water) and idle call air is all made up of extraneous air.When full extraneous air cooling runs, idle call air is all used extraneous air, and control cold water flow, make the coolant-temperature gage difference between the temperature of the temperature of the heat exchange water of the outlet of feed air temperature and heat exchanger coil 9 and the heat exchange water of entrance reach setting value.When cool run, control extraneous air ratio, make the gas concentration lwevel of idle call air reach setting value, and control cold water flow and make feed air temperature and above-mentioned coolant-temperature gage difference reach setting value.Run and in cooling operation, if suction temperature is lower than setting value, then under making gas concentration lwevel not exceed the scope of setting value, reduce air feed air quantity in air-supply operation, full extraneous air cooling, thus controlling as making suction temperature reach setting value.
Fig. 4 is an example of warm water mode operation, when bringing into operation, make the heat exchange water (warm water) of the regulation water yield flow through heat exchanger coil 9, and make the extraneous air ratio of idle call air become 100% and to indoor with certain air quantity air feed, control as making indoor humidity reach setting value.Then, when blowing operation, stopping warm water and idle call air is all made up of extraneous air.When cooling operation in the winter time, stop warm water and idle call air is all made up of extraneous air for the time being, and controlling the return-air ratio of idle call air, under making gas concentration lwevel not exceed range of set value, making feed air temperature reach setting value.When heating operation, controlling extraneous air ratio, making the gas concentration lwevel of idle call air reach setting value, and control warm water flow, make feed air temperature and above-mentioned coolant-temperature gage difference reach setting value.In air-supply operation, cooling operation in winter and heating run, if suction temperature is lower than setting value, then under making gas concentration lwevel not exceed the scope of setting value, reduce air feed air quantity, thus control is for making suction temperature reach setting value.
Fig. 6 is another embodiment, illustrate in a part for the indoor be arranged at beyond ceiling inside as the situation arranging longitudinally upper long cabinet 1 in the enclosure space CS of easy Machine Room.The wall portion 32 forming enclosure space CS is provided with the extraneous air air door 4 regulating air quantity and return-air air door 5.In legend, enclosure space is made up of wall portion 32, floor section 33, partition wall portion 35, but the change formed it is freely.By the conduit 36 be communicated with extraneous air air door 4, extraneous air can also be imported enclosure space.Partition wall portion 35 can utilize dividing plate etc.
