Abstract
The invention discloses an improving structure of air conditioning system, comprising a compressor, a heat interchanger, a throttle, an evaporator, a gas-liquid separator and a device for drying and filtering, wherein the air outlet of the compressor is connected with the evaporator and the heat interchanger by a four-way reversing valve, the entrance of the gas-liquid separator is communicated with the exit of the four-way reversing valve, the exit of the gas-liquid separator is communicated with the entrance of the compressor, the throttle and the device for drying and filtering are arranged between the heat interchanger and the evaporator, and an energy gasholder for adjusting defrosting is arranged between the air outlet of the compressor and the four-way reversing valve. By adding the energy gasholder, the invention ensures that the frost on the evaporator is melted quickly by enough steam pressure and temperature while defrosting, and the efficiency of defrosting is high and the defrosting is clean and thoroughly..
Description
Technical field
The present invention relates to relate to the HVAC field, be specifically related to a kind of air-conditioning system.
Background technology
As Fig. 1, the defrost of existing air-conditioning unit is that system is when reaching the defrost condition, the steam that compressor exhaust pipe is discharged enters valve 7 throttlings of expanding through splashing again of liquid that evaporimeter 8 carries out becoming after the direct defrost cooling HTHP by cross valve 3 and enters heat exchanger 4 and evaporate and become low-pressure low-temperature, its defrost speed is general, defrost efficient is further improved, power consumption can increase like this, and is bigger equally to the ambient influnence of its conditioned space.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of improved structure of air conditioner system, can improve its defrost speed, improves defrost efficient, and defrost is clean.
For solving the problems of the technologies described above, the present invention adopts following technical scheme, a kind of improved structure of air conditioner system, comprise compressor, heat exchanger, choke valve, evaporimeter, gas-liquid separator, device for drying and filtering, described compressor outlet is by four-way change-over valve and evaporimeter and heat exchanger UNICOM, the gas-liquid separator import is communicated with the four-way change-over valve outlet, the gas-liquid separator outlet is communicated with the suction port of compressor, establish choke valve and device for drying and filtering between heat exchanger and evaporimeter, it is characterized in that: also be provided with between described compressor outlet and four-way change-over valve and regulate the energy air accumulator that defrost is used.
The present invention is owing to adopt technique scheme, when the control system system of monitoring needs defrost, control system control condensation cycle water pump quits work, make the condensation temperature of heat exchanger be elevated to uniform temperature, the steam pressure and the temperature of energy air accumulator raise synchronously simultaneously, further store heat, the blower fan of control system control evaporimeter quits work then, control four-way change-over valve again and enter the defrost recurrent state, reach the purpose of defrosting,, have enough steam pressures and temperature that the frost on the evaporimeter is melted fast when making defrost owing to increased the energy air accumulator, defrost efficient height, defrost is clean.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of existing air-conditioning system;
Fig. 2 is the structural representation of a kind of improved structure of air conditioner system embodiment one of the present invention.
The specific embodiment
As shown in Figure 2, be a kind of improved structure of air conditioner system of the present invention, a kind of improved structure of air conditioner system, comprise compressor 1, heat exchanger 4, choke valve 7, evaporimeter 8, gas-liquid separator 9, device for drying and filtering 6, described compressor outlet is by four-way change-over valve 3 and evaporimeter 8 and heat exchanger 4 UNICOMs, gas-liquid separator 9 imports are communicated with four-way change-over valve 3 outlets, gas-liquid separator 9 outlets are communicated with compressor 1 inlet, 8 in heat exchanger 4 and evaporimeter are established choke valve 7 and device for drying and filtering 6, and 3 of described compressor 1 gas outlet and four-way change-over valves also are provided with regulates the energy air accumulator 2 that defrost is used.
Described evaporimeter 8 can also adopt structure as shown in Figure 3, comprise two groups of evaporator units that are arranged in parallel 81, described every group of evaporator unit is communicated with by reversal valve I33 control respectively, compressor 1 return-air mouth is provided with temperature-sensing probe I52, and described reversal valve I33 and temperature-sensing probe I52 are electrically connected with control system.Described heat exchanger also can adopt two groups of heat exchanger units that are arranged in parallel 4, every group of heat exchanger unit 4 is communicated with by reversal valve II32 control respectively, described heat exchanger exit place is provided with temperature-sensing probe II51, and described reversal valve II32 and temperature-sensing probe II51 are electrically connected with control system.I33 of reversal valve described in the present embodiment and reversal valve II are solenoid directional control valve.
Above-mentioned evaporimeter is set to two groups of evaporator units in parallel, and control connection respectively by reversal valve I, in the winter time, when system receives the compressor return air temperature when crossing low signal, system sends signal by wherein one or more groups evaporator unit unlatching of reversal valve I control, make that suction temperature can be not low excessively, thereby make the frosting phenomenon that alleviates outdoor evaporimeter, guarantee system's operate as normal; In summer, when system receives the too high signal of compressor return air temperature, system send signal by reversal valve I control wherein one or more groups evaporator unit close, thereby make the suction temperature can be not too high, guarantee system's operate as normal.And heat exchanger is set to the heat exchanger unit of some groups of parallel connections in parallel, and control connection respectively by reversal valve II, when system receives the heat exchanger exit refrigerant temperature when crossing low signal, system send signal by reversal valve II control wherein one or more groups heat exchanger unit close, thereby alleviate the frosting phenomenon of outdoor evaporimeter, guarantee system's operate as normal.
