Detailed Description
In order that the above objects, features and advantages of the present application can be more clearly understood, the present application will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited by the specific embodiments disclosed below.
As shown in fig. 1, the present embodiment provides an air conditioning system with a low-load dehumidification function, which includes a compressor 1, a condenser 2, an electronic expansion valve 3, an integrated evaporator, and a first fan 9 connected in series, and an air duct is disposed between the integrated evaporator and the first fan 9.
This embodiment sets up the integral type evaporimeter on current air conditioning system's basis, and this integral type evaporimeter includes: a blowing side evaporator 4, a capillary tube 7, and a windward side evaporator 8. Under the low-load dehumidification mode of operation, absorb the outside air heat by windward side evaporator 8, reduce the temperature of air in the wind channel, evaporate the refrigerant, realize air conditioning system's refrigeration function, simultaneously, the vapor in the wind channel air condenses liquefaction on windward side evaporator 8, realizes air conditioning system's dehumidification function. At the moment, the refrigeration requirement of the air conditioning system is low, the air supply side evaporator 4 releases heat to low-temperature air in the air duct, high-pressure refrigerant steam is condensed into high-pressure refrigerant liquid, the net cold output of the air conditioning system is reduced, the air conditioning system can continuously run under low load, and the dehumidified air at the air supply side is heated at the same time.
As shown in fig. 2, in a preferred implementation of the present embodiment, a first electromagnetic valve 5 may also be provided in the integrated evaporator; the first solenoid valve 5 is provided in series with the capillary tube 7 between the air supply side evaporator 4 and the windward side evaporator 8, and the first solenoid valve 5 is placed in an open state in the low load dehumidification mode.
It should be noted that the air conditioning system in this embodiment is further provided with a temperature sensor, a humidity sensor, a pressure sensor, and the like similar to those in the existing air conditioning system, and the control method of the air conditioning system may be implemented by a conventional method. When the first solenoid valve 5 is not provided, since the resistance of the capillary tube 7 to the refrigerant liquid is much larger than that of the second solenoid valve 6, the refrigerant liquid rarely flows through the capillary tube 7 during normal cooling, and there is no need to adjust the control method of the air conditioning system. When the first electromagnetic valve 5 is provided, it is only necessary to switch the opening states of the first electromagnetic valve 5 and the second electromagnetic valve 6 in the low-load dehumidification mode, and the specific control method is not limited in this embodiment.
The air conditioning system in the present embodiment will now be described in detail by taking the example of providing the first electromagnetic valve 5.
In the low-load dehumidification mode, a compressor 1 of the air conditioning system compresses refrigerant gas, conveys the compressed refrigerant gas to a condenser 2 for heat dissipation, and enters an integrated evaporator after passing through an electronic expansion valve 3. It should be noted here that when the air conditioning system is operating in the low-load dehumidification mode, the electronic expansion valve 3 is configured to be in a forced fully open state.
When high-pressure refrigerant steam enters the air supply side evaporator 4 arranged on the air supply side of the air duct, the high-pressure refrigerant steam is condensed into high-pressure refrigerant liquid in the air supply side evaporator 4, and heat is released to air sent out from the air duct, so that the net cold output of the air conditioning system is reduced, and the air conditioning system under low load can continuously run.
In the present embodiment, the first electromagnetic valve 5 and the capillary tube 7 connected in series are disposed between the air supply side evaporator 4 and the windward side evaporator 8, wherein after the first electromagnetic valve 5 is opened, the refrigerant liquid flowing through the air supply side evaporator 4 flows into the windward side evaporator 8 through the first electromagnetic valve 5 and the capillary tube 7, and the capillary tube 7 throttles the refrigerant liquid flowing to the windward side evaporator 8 according to its own structural design, so as to implement the low-load dehumidification function by using the air supply side evaporator 4 and the windward side evaporator 8 together.
In this embodiment, the first solenoid valve 5 and the capillary 7 may be replaced with an electric control valve.
The windward side evaporator 8 of the integrated evaporator is arranged on the windward side of the air channel, and under the action of the first fan 9, outside air enters the windward side of the air channel, and at the moment, the outside air is in a high-humidity state. When the outside air passes through the windward side evaporator 8, the refrigerant liquid in the windward side evaporator 8 absorbs the heat in the outside air in the air duct, the heat is absorbed and evaporated, the liquid state is converted into the gaseous state, and the refrigerant gas is conveyed to the compressor 1 again. And the water vapor in the air at the windward side of the air duct is liquefied when meeting cold and is adsorbed on the windward side evaporator 8. Simultaneously, can reduce the rotational speed of first fan 9 for measure the heat transfer volume and reduce in the air conditioning system, evaporating temperature reduces, makes 8 surfaces of windward side evaporimeters change the condensate water, and the water after condensing alright via drain pipe discharge air conditioning system realizes air conditioning system's dehumidification function.
The air temperature in the air duct after being absorbed is reduced, and is conveyed to the air supply side evaporator 4 along the air duct, and under the action of the heat released by the air supply side evaporator 4, the air temperature is increased as thermal compensation, and is discharged from the air duct by the first fan 9 to enter the indoor environment, so that the low-load dehumidification function of the air conditioning system is realized.
Further, the air conditioning system further includes: a second electromagnetic valve 6; the second electromagnetic valve 6 is connected in parallel to the first electromagnetic valve 5 and two ends of the windward side evaporator 8.
The direction of the wind of the integrated evaporator is shown by the arrows in fig. 3. In this embodiment, the heat exchange area of the air supply side evaporator 4 is larger than that of the windward side evaporator 8, and when the air conditioning system is in a low load state, the thermal compensation amount is much smaller than the rated cooling amount (the cooling amount during normal operation), so that the heat exchange area of the air supply side evaporator 4 is set to be larger than that of the windward side evaporator 8, so as to satisfy the low load dehumidification function of the air conditioning system.
Under this background, when air conditioning system normal refrigeration operation, the air supply side evaporimeter 4 can cause the huge difference of heat exchanger branch road flow with the difference of 8 heat transfer areas of windward side evaporimeter, and the 4 exports of air supply side evaporimeter are gaseous state refrigerant mostly simultaneously, and when gaseous state refrigerant multipath entering few flow paths, the resistance loss of single flow path will obviously increase, causes suction pressure to evaporate pressure reduction promptly obvious, makes the refrigeration volume reduce, the consumption increases.
Therefore, the second electromagnetic valve 6 is connected in parallel to the first electromagnetic valve 5 and the two ends of the windward side evaporator 8, when the air conditioning system normally operates in a refrigerating mode, the second electromagnetic valve 6 is opened, the first electromagnetic valve 5 is closed, and the refrigerant is prevented from entering the windward side evaporator 8 with a small heat exchange area and directly flowing to the compressor 1.
In summary, when the air conditioning system is operating in the cooling mode (non-low-load dehumidification mode), the second solenoid valve 6 is configured in the open state; when the second solenoid valve 6 is in the open state, the first solenoid valve 5 is configured in the closed state.
Specifically, when the air conditioning system performs normal refrigeration, the second electromagnetic valve 6 is in an open state, the first electromagnetic valve 5 is in a closed state, and the refrigerant passes through the air supply side evaporator 4, the second electromagnetic valve 6 and the windward side evaporator 8 in sequence by the electronic expansion valve 3 and then enters the compressor 1 again, so that the refrigerant circulation is realized, and the indoor air is refrigerated.
At this time, the function of the integrated evaporator is the same as that of a conventional evaporator in an air conditioning system, and the electronic expansion valve 3 operates according to a normal refrigeration logic.
It should be noted that, when the air conditioning system operates in the low load dehumidification mode, the initial state of the second fan 10 arranged in parallel with the condenser 2 is configured to be the standby state or the low wind speed state, and after the exhaust pressure, i.e. the condensation pressure, in the air conditioning system meets the preset pressure condition, the second fan 10 is changed from the standby state or the low wind speed state to the normal operation state, so as to ensure the stable operation of the air conditioning system, and make the condensation heat of the refrigerant not be completely condensed and discharged at the condenser 2, so as to reserve a part of heat release margin for the air supply side evaporator 4.
The second fan 10 and the condenser 2 may be replaced with a water-cooled condenser.
