In the technical solution of the utility model, also have following technical characterictic: described electric expansion valve comprises electric expansion valve A and electric expansion valve B, described electric expansion valve A is arranged on the online pipeline between described high pressure reservoir and the described heat exchanger, described electric expansion valve A outlet is divided into two-way, one the tunnel enter in the heat exchanger cross cold after, enter evaporimeter through online pipe, get back to compressor through online pipe again; Another road is through after being arranged on the described electric expansion valve B throttling on this road, and entering in the heat exchanger evaporation heat absorption becomes gas and return in the compressor.
In the technical solution of the utility model, also have following technical characterictic: described heat exchanger is a plate type heat exchanger.
In the technical solution of the utility model, also have following technical characterictic: described plate type heat exchanger is arranged in the air-conditioner outdoor unit.
In the technical solution of the utility model, also have following technical characterictic: described online length of tube scope is a 15-50 rice.
In the technical solution of the utility model, also have following technical characterictic: the online pipe between described heat exchanger and the described evaporimeter is thin online pipe, and the online pipe between described evaporimeter and the described compressor is thick online pipe.
A kind of air-conditioner is equipped with the described air conditioner refrigerating/heating recycle system of technique scheme.
System configuration of the present utility model mainly is to allow length for the online pipe that improves cabinet air conditioner.
The cabinet air conditioner system is made up of compressor, evaporimeter, condenser, high pressure reservoir, electric expansion valve A, electric expansion valve B, plate type heat exchanger, thick online pipe, thin online pipe.The compressed machine of refrigerant is collapsed into the HTHP gas and enters in the outdoor condenser, and refrigerant condensation in condenser becoming high pressure saturated liquid passes through the high pressure reservoir again, is divided into two-way after the liquid refrigerants process electric expansion valve A throttling step-down of coming out.One the tunnel enter in the plate type heat exchanger cross cold after, cross cold and improve greatly, entering cabinet air-conditioner indoor machine evaporation evaporation heat absorption through meticulous online pipe becomes overheated gas, gets back to compressor through thick online pipe again; One the tunnel through after the electric expansion valve B throttling in plate type heat exchanger the evaporation heat absorption become gas and return in the compressor.
The utility model can be widely used in the design and production of cabinet air conditioner.The online pipe of cabinet air conditioner can allow length to bring up to 50 meters by 15 meters.
The utility model compared with prior art has the following advantages and good effect:
1, because in air conditioner circulating system, added plate type heat exchanger, the one tunnel enter cross in the plate type heat exchanger cold after, the cold of crossing of refrigerant greatly improves, thereby the length of online pipe can extend, and can allow length to bring up to 50 meters by 15 meters.
2, plate type heat exchanger is that two-way advances two-way and goes out, and in the heat exchange each other of plate type heat exchanger inside, has improved heat exchange efficiency and Energy Efficiency Ratio between the two-way.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is a kind of air conditioner refrigerating/heating recycle system schematic diagram;
1, condenser; 2, high pressure reservoir; 3, compressor; 3-1, exhaust outlet of compressor; 3-2, compressor air suction mouth; 4, cross valve; 5, electric expansion valve A; 6, electric expansion valve B, 7, plate type heat exchanger; 8, online pipe; 9, evaporimeter; 10, stop valve.
The specific embodiment
Referring to Fig. 1, the utility model is in order to solve the refrigerant flass that online length lengthening back occurs, to make air-conditioning system refrigerating/heating ability that the problem than high attenuation be arranged.
The flow direction of refrigerant is that to flow to the refrigerant kind of refrigeration cycle be the direction foundation.During refrigeration, the flow direction of refrigerant is by compressor 3 → cross valve 4 → condenser 1 → high pressure reservoir 2 → electric expansion valve A5 → be divided into two-way, one tunnel → plate type heat exchanger 7 → thin online pipe → evaporimeter 9 → thick online pipe → cross valve 4 → compressor 3; Another road electric expansion valve B6 → plate type heat exchanger 7 → compressor 3.
On the online pipeline 8 of described high pressure reservoir 2 outlets, be provided with plate type heat exchanger 7.
Online pipe 8 between described plate type heat exchanger 7 and the described evaporimeter 9 is thin online pipe, and the online pipe 8 between described evaporimeter 9 and the described compressor 3 is thick online pipe.The thickness of online pipe diameter is determined according to factors such as types.
Comprise two electric expansion valve A, B in the system of the present utility model, described electric expansion valve A5 is arranged between high pressure reservoir 2 and the plate type heat exchanger 7, described electric expansion valve A5 outlet is divided into two-way, one the tunnel enter in the plate type heat exchanger 7 cross cold after, strengthened the cold of crossing of refrigerant greatly, entering cabinet air-conditioner indoor machine evaporation 9 evaporation heat absorptions through meticulous online pipe 8 becomes overheated gas, gets back to compression 3 machines through thick online pipe 8 again; In plate type heat exchanger 7, evaporate heat absorption after the process electric expansion valve B6 throttling step-down of another road and become the air entry 3-2 that gas returns compressor 3.
