Description
Technical field
The utility model relates to the technical field of air-conditioner in the electric equipment, more particularly, relates to a kind of according to the residing changes in environmental conditions of air-conditioner and the air-conditioner that self adaptation is regulated.
Background technology
The refrigeration system of existing air-conditioner is made up of compressor, condenser, throttle part and evaporimeter, and throttle part generally all adopts capillary.
Capillary as the advantage of throttle part is: simple in structure, easily manufactured, cost is low, not fragile, but aperture capillaceous and length are to determine according to certain environmental condition, when the load variations of evaporimeter, it can not adapt to well, if evaporating pressure descends, the phenomenon that refrigerant liquid enters compressor takes place easily, if evaporating pressure rises, then can make evaporimeter feed flow deficiency again, influence giving full play to of system's refrigerating capacity, both of these case all can have influence on the service property (quality) and the service life of air-conditioner.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art and a kind of air-conditioner of regulating according to the changes in environmental conditions self adaptation is provided, liquid supply rate according to air-conditioner operating mode control of living in evaporimeter makes air-conditioner can both obtain good refrigeration or heating effect under various environmental conditions.
For solving the problems of the technologies described above, technical scheme of the present utility model is: the air-conditioner that a kind of self adaptation is regulated, throttle system comprises expansion valve, the pressure transfer tube, temperature-sensitive pipe and compressor return air pipe, described valve expansion valve is provided with the bellows chamber, the output of described temperature-sensitive pipe is connected with the top, bellows chamber of expansion valve, and the power that applies is in diaphragm top, described pressure transfer tube is connected with the bottom, bellows chamber of expansion valve, and the power that applies is in the diaphragm bottom, the bellows chamber changes the action of controlling diaphragm according to the temperature and pressure of compressor return air pipe, thereby the valve opening size of control expansion valve, expansion valve is respectively equipped with in the junction chamber, the indoor interface and the outdoor interface of outside heat exchanger.
Described expansion valve is arranged on the air conditioner chamber outside or air conditioner chamber inboard.
Described expansion valve is provided with one or more.
The utility model with respect to the beneficial effect of prior art is:
The air-conditioner that has two-way heating power expansion valve that the utility model provides, compared with prior art have the following advantages: air-conditioner is because changes in environmental conditions can cause the degree of superheat of evaporimeter to change, the utility model is by the degree of superheat of sensing evaporator, and control by the aperture of regulating two-way heating power expansion valve, make the reasonable feed flow of evaporimeter, make refrigeration system be in normal operating conditions, ensured the service property (quality) and the service life of air-conditioner.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model is the air-conditioner of regulating according to the changes in environmental conditions self adaptation, its throttle system comprises expansion valve 101, back pressure transfer tube 104, temperature-sensitive pipe 105, compressor return air pipe 106, expansion valve 101 is provided with the bellows chamber, the output of temperature-sensitive pipe 105 is connected with the top, bellows chamber of expansion valve 101, and the power that applies is in diaphragm top, pressure transfer tube 104 is connected with the bottom, bellows chamber of expansion valve 101, and the power that applies is in the diaphragm bottom, the bellows chamber changes the action of controlling diaphragm according to the temperature and pressure of compressor return air pipe 106, thereby the valve opening size of control expansion valve 101, therefore expansion valve 101 claims two-way heating power expansion valve again, and expansion valve 101 is respectively equipped with in the junction chamber, the indoor interface 103 of external heat exchanger, outdoor interface 102
Operation principle of the present utility model is:
When the environmental condition of air-conditioner was stablized, up and down power was in poised state in the bellows chamber of two-way heating power expansion valve 101, and the aperture of valve remains unchanged.When the changes in environmental conditions of air-conditioner causes the load of evaporimeter to increase, the return-air degree of superheat increases, and the temperature that temperature-sensitive pipe 105 is experienced increases, and power downward in the bellows chamber of two-way heating power expansion valve 101 increases, the aperture of valve also increases, and the amount of liquid refrigerant of supplying with evaporimeter just increases.Otherwise, when the changes in environmental conditions of air-conditioner causes the load of evaporimeter to reduce, the return-air degree of superheat reduces, the temperature that temperature-sensitive pipe 105 is experienced decreases, power downward in the bellows chamber of two-way heating power expansion valve 101 reduces, the aperture of valve also reduces, and the amount of liquid refrigerant of supplying with evaporimeter just reduces.
The course of work of the present utility model is:
Air-conditioning is when refrigerating operaton, and the high-temperature high-pressure refrigerant liquid that outdoor heat exchanger is come flows into two-way heating power expansion valve 101 throttlings through outdoor interface 102, evaporates in the inboard heat exchanger of inlet chamber behind indoor interface 103 again.
Air-conditioning is when heating operation, and the high-temperature high-pressure refrigerant liquid that indoor heat exchanger is come flows into two-way heating power expansion valve 101 throttlings through indoor interface 103, evaporates in the heat exchanger of the inlet chamber outside behind outdoor interface 102 again.
