Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

In yellow plum season and summer, the central air conditioner of the room provided with the aviation simulator equipment can effectively control the room temperature, but the relative humidity can not be controlled below 80% all the time, and the problem of high failure rate of the aviation simulator equipment is easily caused.

In view of the above, the present utility model provides a multifunctional dehumidifier including an outdoor unit and an indoor unit; the outdoor unit includes a compressor 110 and a first condenser 120; the indoor unit includes an indoor condenser 210, a capillary tube throttling assembly 220, an evaporator 230, and an indoor fan 240; refrigerant may circulate along the compressor 110, the first condenser 120, the indoor condenser 210, the capillary tube restriction 220, and the evaporator 230; capillary tube throttling assembly 220 is used to change the refrigerant from a liquid state to a gas-liquid mixed state; the indoor fan 240 blows indoor air into the evaporator 230 for dehumidification, and then the indoor air is heated by the indoor condenser 210 and returned to the room.

The multifunctional dehumidifier provided by the utility model has the advantages that the conventional condenser is divided into two parts, the first condenser 120 is arranged outdoors, the indoor condenser 210 is arranged indoors, the normal refrigerating capacity is ensured, the evaporator 230 can absorb enough heat to liquefy moisture in the air, and meanwhile, the indoor condenser 210 can heat the dehumidified air, so that the indoor temperature is prevented from being reduced due to dehumidification, the constant-temperature dehumidification is realized, the load of a central air conditioner is prevented from being increased, and the energy consumption of the central air conditioner is prevented from being increased due to the increase of the dehumidifier. Especially, low temperature air can lead to the cooling in the room, and the cooling process can lead to relative humidity to improve, is unfavorable for the control to relative humidity.

The conventional dehumidifier can cause the indoor temperature to rise due to the arrangement in the room, so that the load of the central air conditioner is increased, the energy consumption is increased, and the economical efficiency is poor. Moreover, the large dehumidifier of the finished product has large volume, can reduce the utilization rate of indoor space, affects the layout of the existing aviation simulator equipment, can cause equipment moving cost, and can also affect the simulation training due to the noise generated by the compressor 110 indoors.

The utility model realizes heat balance by arranging the evaporator 230 and the indoor condenser 210 in the room, ensures constant temperature dehumidification, and has the advantages of small occupied area and flexible arrangement while the compressor 110 is arranged outdoors to avoid noise influence.

The structure and shape of the multifunctional dehumidifier provided in this embodiment are described in detail below with reference to fig. 1 to 6:

in this embodiment, the outdoor unit includes a compressor 110, a first condenser 120, a second condenser 130, an outdoor solenoid valve 140, and a check valve, and the indoor unit includes an indoor condenser 210, a capillary stop assembly 220, an evaporator 230, an indoor fan 240, an indoor solenoid valve 250, an indoor check valve 260, and a drain pipe 270, as shown in fig. 1.

The refrigerant circulates sequentially along the compressor 110, the first condenser 120, the outdoor solenoid valve 140, the indoor condenser 210, the indoor check valve 260, the capillary tube restriction assembly 220, and the evaporator 230 to form a constant temperature dehumidification loop, as shown in fig. 3; the refrigerant circulates sequentially along the compressor 110, the first condenser 120, the second condenser 130, the outdoor check valve 150, the indoor solenoid valve 250, the capillary tube restriction assembly 220, and the evaporator 230 to form a cool down dehumidification loop, as shown in fig. 4.

Wherein, the indoor check valve 260 and the outdoor check valve 150 are used to prevent the reverse flow of the refrigerant, thereby preventing the generation of turbulence and backflow. Specifically, the outdoor check valve 150 is connected in series with the second condenser 130, the outdoor solenoid valve 140 is connected in parallel with the outdoor check valve 150 and the second condenser 130, and the outdoor check valve 150 may be disposed at an inlet or an outlet of the second condenser 130; the indoor check valve 260 is connected in series with the indoor condenser 210, the indoor solenoid valve 250 is connected in parallel with the indoor check valve 260 and the indoor condenser 210, and the indoor check valve 260 may be disposed at an inlet or an outlet of the indoor condenser 210. In this embodiment, the outdoor check valve 150 is preferably disposed at the outlet of the second condenser 130, and the indoor check valve 260 is preferably disposed at the outlet of the indoor condenser 210, so that the effects of turbulence and backflow prevention are better.

In this embodiment, the indoor unit further includes a drain pipe 270, one end of the drain pipe 270 is connected to the evaporator 230, and the other end is a drain port for draining water; wherein the drain outlet is located outdoors.

The working process of the multifunctional dehumidifier provided by the embodiment is as follows:

constant temperature dehumidification working process: the compressor 110 performs work to change the refrigerant into a high-temperature and high-pressure body, then the refrigerant is pre-cooled by the first condenser 120, the pre-cooled refrigerant enters the indoor condenser 210 through the outdoor electromagnetic valve 140 to sufficiently cool the refrigerant, so that a high-pressure liquid refrigerant is formed, the liquid refrigerant is changed into a low-temperature and low-pressure gas-liquid mixture after passing through the capillary throttling assembly 220, then the refrigerant enters the evaporator 230 to absorb the heat of air, and is changed into a low-temperature and low-pressure gaseous refrigerant, and finally the low-temperature and low-pressure gaseous refrigerant returns to the compressor 110 to perform work and is changed into a high-temperature and high-pressure gaseous refrigerant. The indoor wet air is blown into the evaporator 230 by indoor air, and the low-temperature low-pressure gas-liquid mixed state refrigerant flowing through the evaporator 230 absorbs heat to cool the wet air, so that the moisture in the air is liquefied, and finally the air is discharged out of the room through the drain pipe 270, so that the moisture in the air is removed, and the dehumidification effect is achieved; the dehumidified air flows through the indoor condenser 210 to be heated by the indoor condenser 210, so that the air cooled by the evaporator 230 is heated to be close to the indoor temperature, and the dry air close to the indoor temperature is obtained, thereby realizing constant-temperature dehumidification, avoiding the increase of heat load and air conditioner energy consumption in the dehumidification process, being beneficial to maintaining a constant-temperature state and avoiding the fluctuation of the indoor temperature.

The working process of cooling and dehumidifying comprises the following steps: compared with the constant temperature dehumidification process, the difference is that the refrigerant is pre-cooled by the first condenser 120, fully cooled by the second condenser 130 to form high-pressure liquid refrigerant, and then sequentially passes through the indoor electromagnetic valve 250 and the capillary throttling assembly 220 to enter the evaporator 230, namely the refrigerant circulates along the cooling and dehumidification loop. At this time, the refrigerant no longer passes through the outdoor solenoid valve 140 and the indoor condenser 210, and the dehumidified air no longer passes through the indoor condenser 210 to be preheated, but directly enters the room, i.e., is operated in a full-cooling mode.

In the actual use process, the indoor air is firstly operated in a constant temperature dehumidification mode to enable the room to reach the set relative humidity, then is operated in a cooling dehumidification mode, and at the moment, the indoor air is cooled by the evaporator 230 and then enters the room, so that the heat dissipation capacity of other equipment is balanced, and the work load of the central air conditioner is reduced. When the indoor humidity exceeds a set value, the indoor temperature is operated in a constant-temperature dehumidification mode again, so that the step-type cooling is realized on the premise of controlling the indoor relative humidity, and the effects of reducing the indoor temperature and reducing the energy consumption are achieved.

It should be noted that, the dehumidifying effect of constant temperature dehumidification is stronger than cooling dehumidification, because according to the wet air enthalpy and humidity characteristics, the low temperature air can be cooled when entering the room, the indoor relative humidity can be improved in the cooling process, and the indoor relative humidity can not be effectively controlled. Therefore, in the actual operation process, the constant temperature dehumidification mode and the temperature reduction dehumidification mode are alternately operated, so that a good humidity control effect is obtained, and the aim of reducing energy consumption is fulfilled.

In the present embodiment, the refrigerant is changed in passage by simply connecting solenoid valves in parallel due to the resistances of the second condenser 130 and the indoor condenser 210 themselves. Specifically, as shown in fig. 3, at this time, the outdoor solenoid valve 140 is turned on, and the refrigerant flows along the path of small resistance, so that the refrigerant does not pass through the second condenser 130. Likewise, as shown in FIG. 4, when the indoor solenoid valve 250 is on, refrigerant no longer passes through the indoor condenser 210, but directly enters the capillary tube throttling assembly 220.

In an alternative to this embodiment, capillary tube restriction assembly 220 includes a plurality of capillary tubes in parallel and a one-way valve disposed at the outlet end of the capillary tubes. The high-pressure liquid refrigerant is subjected to a certain resistance when passing through the capillary tube, and the liquid refrigerant coming out of the capillary tube is rapidly diffused at the outlet end of the capillary tube, so that the liquid refrigerant becomes a low-temperature low-pressure gaseous mixture.

In an alternative scheme of this embodiment, the multifunctional dehumidifier further includes a humidity sensor and a controller, the humidity sensor is electrically connected with the controller, and the controller is electrically connected with the indoor electromagnetic valve 250 and the outdoor electromagnetic valve 140 to control on-off of the indoor electromagnetic valve 250 and the outdoor electromagnetic valve 140. The humidity sensors are arranged indoors and used for monitoring relative humidity changes and timely dehumidifying, and the positions of the humidity sensors are arranged according to the dehumidifying range of the multifunctional dehumidifier. The controller controls the operation of the indoor solenoid valve 250, the outdoor solenoid valve 140, the indoor fan 240, the compressor 110, etc. according to the information monitored by the humidity sensor, thereby realizing the switching of the dehumidification mode. Wherein, the controller can select singlechip.

In an alternative of this embodiment, the drain pipe 270 is provided with a trap 271, and the end of the trap 271 connected to the evaporator 230 is higher than the end connected to the drain port. As shown in fig. 5, since the indoor fan 240 blows air into the evaporator 230, the air pressure at the evaporator 230 is lower than the outdoor air pressure, and at this time, the water is not easily discharged from the drain pipe 270 due to the obstruction of the outdoor air pressure. By arranging the trap 271, the end connected with the evaporator 230 is higher than the end connected with the water outlet, so that a certain liquid pressure difference is formed, the air pressure difference is compensated, the obstruction of the air pressure difference to the liquid flow is eliminated, the liquid is smoothly discharged outdoors, and the normal dehumidification operation is ensured. I.e., the liquid level at the end connected to the evaporator 230 is gradually raised after the air pressure difference leaves the liquid in the water, and the liquid can normally flow after the air pressure difference is enough to offset the air pressure difference.

In an alternative of this embodiment, the compressor 110 is connected to the evaporator 230 through an air return pipe, and the air return pipe is provided with an oil storage bend 281, where the oil storage bend 281 is configured in a U shape and the opening of the U shape is upward. As shown in fig. 6, the muffler includes an outdoor stand pipe, an oil trap 281, and a connection pipe, both ends of the oil trap 281 are connected to the outdoor stand pipe and the connection pipe, respectively, the outdoor stand pipe is connected to the evaporator 230, and the connection pipe is connected to the compressor 110. Because the indoor area is large, the installation distance between the indoor unit and the outdoor unit can be more than 10 meters, and at this time, because the muffler is too long, the refrigerating oil in the mixed load refrigerant can remain in the pipeline, so that the refrigerating oil in the compressor 110 is insufficient, and the operation safety of the compressor 110 is affected. Wherein, the refrigerating oil lubricates the compressor 110, and part of the refrigerating oil is mixed with the refrigerant and enters the indoor unit during operation, and the refrigerating oil is returned to the compressor 110 under the action of gravity and gas. When the piping is too long, the oil disperses and the gas is unable to effectively carry the refrigerant oil to the compressor 110. At this time, the oil storage bend 281 is arranged to gather the frozen oil carried by the gas, and the frozen oil can plug the air return pipe along with the gathering of the oil, so that the gaseous refrigerant can effectively carry a large amount of frozen oil to return to the compressor 110 to ensure the normal operation of the compressor 110, and the situation that the frozen oil is accumulated at the connecting pipe and cannot flow back is avoided. It should be noted that, the outdoor vertical tube is vertically arranged, and this section of frozen oil can flow to the oil storage bend 281 to gather under the action of gravity, which is helpful for the backflow of the frozen oil. Also, the oil trap 281 may be provided as a U-shaped bend, with the opening of the U being upward.

In an alternative scheme of the embodiment, the multifunctional dehumidifier further comprises a sectional timing controller, and the sectional timing controller is used for realizing multi-use valley electricity and flat-period electricity, less peak electricity and no peak period electricity, and peak valley electricity is matched to realize energy saving and consumption reduction.

Most of existing finished large-sized dehumidifiers are of an integrated structure, the compressed refrigeration cycle based on the Kano cycle principle is utilized, humid air is pumped into the dehumidifier by an air inlet fan, the air is reduced to be below the dew point temperature under the interaction of a refrigeration system such as a compressor 110, an evaporator 230, a throttling device, a condenser and the like, and condensed into condensed water to remove moisture in the air and generate dry air for discharge, so that the indoor humidity is reduced by the circulation, and the humid space gradually achieves a dry effect. But it has the following problems: the heat load is increased indoors, the relative humidity is reduced, the room temperature is increased, the load of a central air conditioner is increased, the energy consumption is increased, and the energy is not saved and the method is uneconomical; the finished large dehumidifier has a large size, can reduce the effective utilization rate of room space, directly obstruct the existing normal operation mode and influence the equipment layout; the noise caused by the components such as the compressor 110 and the like in the finished large dehumidifier can also directly influence the daily training.

The multifunctional dehumidifier provided by the embodiment is characterized in that the compressor 110 is arranged outdoors, the condenser is divided into the indoor part and the outdoor part, the operation of the two modes is realized while the noise is reduced, the constant temperature dehumidification mode avoids the increase of the heat load in the dehumidification process, the cooling dehumidification mode can assist the central air conditioner to cool, the energy consumption is effectively reduced, and the stability of the temperature is ensured while the relative humidity is controlled. The constant temperature dehumidification mode does not cause relative humidity improvement due to the fact that low-temperature air enters the room, and dehumidification efficiency is higher; the cooling and dehumidifying mode controls the humidity and simultaneously fully utilizes the refrigeration capacity to assist in refrigeration.

In general, the central air conditioner is not started when the passenger aviation simulator room is not provided with courses, and the energy consumption required by starting the central air conditioner for individual rooms in the whole park is high, because the central air conditioning system needs equipment such as a chilled water pump, a cooling tower, a cold water host machine and the like besides a combined air conditioning box in the room, and the combined air conditioning box is too little in starting, so that the central air conditioner has low energy efficiency and high relative energy consumption. Therefore, after the multifunctional dehumidifier is operated in the constant temperature dehumidification mode to enable the indoor space to reach the required relative humidity, the cooling dehumidification mode is started to reduce the temperature of the room and control the humidity, and the configured cold quantity of the multifunctional dehumidifier is fully utilized. The energy efficiency ratio of the central air conditioner is high compared with that of the central air conditioner which only opens part of the combined air conditioner. If the relative humidity rises again in the cooling and dehumidifying process, the constant temperature dehumidifying mode is automatically switched to, so that the room is cooled in a step-type manner on the premise of controlling the relative humidity, and the energy consumption saving for reducing the temperature of the room is realized.

In addition, the energy utilization strategy of 'peak shifting and valley filling' is adopted, the electricity charge in the valley and normal period is low, a central air conditioner is not used before the official working in the daytime, the multifunctional dehumidifier can be used for controlling the relative humidity and reducing the room temperature with lower energy consumption and cost, and therefore the energy consumption of the multifunctional dehumidifier and the central air conditioner is reduced.

The method is specifically applied to the following steps that the area of a room provided with aviation simulator equipment is 1700 square meters, the length of the room is 42.5 meters, the width of the room is 40 meters, the height of a suspended ceiling is 3.5 meters, the height of the suspended ceiling is 2 meters, 4 combined air conditioning boxes are arranged in the room, and main parameters of each combined air conditioning box are as follows: air volume 30000/H, cooling capacity 98kW and motor power 18.5kW.

(1) And (5) measuring and calculating the dehumidifying amount: the general calculation formula is W=V×ρ× (X1-X2)/(1000×1.2);

wherein W is the required amount of dehumidification (kg/h); ρ -air Density (kg/m) ³ ) The method comprises the steps of carrying out a first treatment on the surface of the V—venue volume; x1-air moisture content before dehumidification (g/kg); x2-the moisture content of the dehumidified air (g/kg); 1000-g is converted into kg; 1.2-safety factor (loss).

Taking Huang Meitian relative humidity 98%, room temperature 23 ℃ and control relative humidity to 60%, obtaining corresponding moisture content through checking an enthalpy-humidity graph, and measuring and calculating required dehumidification W=58.96 kg/h.

(2) And (5) dehumidification cooling capacity measurement: the general calculation formula is Q= (H1-H2) x 1.2 xF 3600;

wherein, the cold quantity Q (kW) required by dehumidification; h1-enthalpy value of humid air before dehumidification (kJ/kg); h2-enthalpy value of humid air after dehumidification (kJ/kg); f-amount of treated air (m ³ /h); 1.2—safety factor (loss); 3600-hours are converted to seconds.

Considering room temperature of 23 ℃, circulating air volume 2 times per hour, and air volume of 11900m ³ According to the measurement and calculation of/H, the checked enthalpy-humidity diagram H1 is 66.106kJ/kg when the relative humidity is 98%, and the H2 control target relative humidity is 50.005kJ/kg when the relative humidity is 60%; the calculated amount of cooling required for dehumidification q= 63.8673kW.

(3) Actual configuration and installation of the dehumidifier:

four multifunctional dehumidifiers are arranged in the room, and the indoor units and the air pipes are hidden in the suspended ceiling, so that the uniform distribution of air quantity and air flow organization, the minimization of noise of the indoor fan 240 and the reasonable space of the suspended ceiling are realized. Main parameters of each dehumidifier are as follows: indoor circulation air quantity 4000m ³ And/h, cooling capacity configuration is 15kW, and power is 6kW. Wherein, an oil storage bend 281 is installed in the outdoor vertical pipe of the muffler of the two multifunctional dehumidifiers with longer indoor unit and outdoor unit connection pipes. The height of the oil trap 281 is set to 3-5 times of the pipe diameter.

In order to achieve effective unloading (0, 50%, 100%) of the energy of the multifunctional dehumidifier, each dehumidifier (power 6 kW) adopts a double refrigeration circuit, namely two compressors 110 (3 kW each) are used, thereby achieving further accurate control of the relative humidity through a single-chip microcomputer. The power supply of the multifunctional dehumidifier is controlled by the multifunctional timer to supply power in a time-sharing manner on site, so that the energy saving and cost reduction of 'peak shifting and valley filling' are realized by using the valley and flat time as much as possible and using less peak and no peak time.

Specifically, in the transition seasons 4 and 5 months, 4 multifunctional dehumidifiers are put into operation in the valley period through a time-sharing power supply function, two dehumidifiers are started in the normal period, the multifunctional dehumidifiers are automatically operated according to a cooling dehumidification mode when power is transmitted from 1 point to 8 points and from 11 points to 16 points, the relative humidity and the room temperature can be effectively controlled without power transmission in other periods, the room temperature is controlled to be about 23 ℃, the relative humidity is below 80%, and a central air conditioner is not required to be started in the whole process. In the yellow plum season and summer, 4 dehumidifiers are put into the valley period to operate through a time-division power supply function, the two dehumidifiers are started in the flat and peak periods and avoid the peak period, the specific period is 1 point to 12 points, and 14 to 16 points are powered on to enable the dehumidifiers to automatically operate according to a cooling dehumidification mode, if the weather forecast red high-temperature early warning is more than 38 ℃, a combined air conditioning box is assisted to be started to operate, the relative humidity and the room temperature can be effectively controlled, and the room temperature is controlled to be about 23 ℃ and the relative humidity is controlled to be below 80%.

And obtaining the energy consumption comparison with the starting of the central air conditioner through the actual use data. In the transition seasons of 4 months and 5 months, the multifunctional dehumidifier is started for 10 hours, the multifunctional dehumidifier consumes 180 degrees of electric energy (4 operation in 5 hours and 2 operation in 5 hours), the central air conditioner consumes 980 degrees of electric energy, and the multifunctional dehumidifier can save 800 degrees of electric energy every day. And starting two combined air conditioning boxes in a transitional season, and calculating according to the cooling capacity of each 98kW and the energy efficiency ratio of 2.0 to estimate each consumed 49kW of power. In practice, the central air conditioning system is started for only a few rooms, and at the moment, high-power equipment such as a refrigeration circulating pump, a cooling tower, a cold water main machine and the like are started, so that the energy efficiency ratio is not high, and is far smaller than 2.0.
