Problems solved by technology
[0002] When the evaporative-condensing heating and cooling air conditioner is in heating operation, if the outdoor temperature is too low, the evaporator of the air conditioner is prone to frost. When the evaporator is frosted to a certain extent, it must be defrosted, otherwise it will affect the air conditioning heat effect
The defrosting action of ordinary evaporative-condensing heating and cooling air conditioners is usually the switching of the four-way valve, that is, switching from heating operation to cooling operation. If the switching of the four-way valve is too frequent, one will affect the service life of the four-way valve, and the other will be Reduce the heating effect and affect the comfort of air conditioning
The refrigeration circuits of the existing evaporative and condensing heating and cooling air conditioners are equipped with multiple solenoid valves or multiple four-way valves. The structure of the refrigerant circulation circuit is complex, and the valves will inevitably leak, resulting in high failure rates, poor reliability, and low efficiency.
