Abstract

The invention discloses an air source heat pump ultrasonic defrosting system, which relates to the defrosting system of the products such as household and commercial air source heat pump, etc. The invention comprises a compressor, a four-way valve, an indoor heat exchanger, a heating cone-way valve, a heating expansion valve, a refrigeration cone-way valve, a refrigeration expansion valve, an outdoor heat interchanger, and an air-fluid separator, wherein, the four-way valve is respectively connected with the compressor, the indoor heat exchanger, the outdoor heat interchanger and the air-fluid separator, the indoor heat exchanger is connected with the heating cone-way valve and the heating expansion valve, the heating cone-way valve and the heating expansion valve are connected with one end of the refrigeration cone-way valve and the refrigeration expansion valve through a pipeline, and the other ends of the refrigeration cone-way valve and the refrigeration expansion valve are connected with the outdoor heat interchanger. The invention is characterized in that an ultrasonic launcher and a temperature sensor are respectively arranged on the outdoor heat interchanger, and the ultrasonic launcher is connected with the temperature sensor through a controller. The invention realizes the purposes of improving the defrosting speed, reducing the energy consumption of the defrosting, and improving the operation efficiency of the heat pump.

Description

technical field [0001] The invention relates to a defrosting system for products such as household and commercial air source heat pumps. Background technique [0002] Air source heat pumps have been widely popularized because of their high energy utilization coefficient, environmental protection, year-round heating and cooling supply of air conditioners, and easy installation and use. However, when the heat pump is running in winter, frosting has a serious adverse effect on the performance of the heat pump, such as blocking the passage between the fins and increasing the air flow resistance; increasing the thermal resistance of the heat exchanger and reducing the heat transfer capacity; reduction, deterioration of heat pump performance, etc. Therefore, effective defrosting is one of the key technologies to solve the problem of heat pump running in winter. After the air conditioner is used for a period of time in winter, the compressor will stop rotating. At this time, the ...
