Ultralow-temperature air energy heat pump set and using method thereof

Abstract

The invention discloses an ultralow-temperature air energy heat pump set and a using method thereof, and solves the technical problems that in the prior art, a condenser of the existing air energy heat pump set can not normally defrost and has poor defrosting effect under ultralow temperature condition, an air energy heat pump water heater or heating air conditioner can not normally work when frosting is severe, and the like. The ultralow-temperature air energy heat pump set has the advantages that the structure is simple, the condenser can automatically defrost and has good defrosting effect, and the energy consumption is reduced. The ultralow-temperature air energy heat pump set is characterized in that: a condenser temperature sensor and multiple groups of heating fins are arranged on the condenser of the device, the heating fins are parallel to the fins of the condenser and are fixed on a copper pipe of the condenser, a water temperature sensor is arranged inside a water tank, a compressor, the heating fins, the condenser temperature sensor and water temperature sensor are connected with an external power supply through a controller, and the controller is used for automatically controlling the opening / closing of the heating fins according to the temperature measured by the condenser temperature sensor and the water temperature sensor.

Description

technical field [0001] The invention relates to an air source heat pump unit, in particular to an ultra-low temperature air source heat pump unit with a condenser capable of automatic defrosting and energy saving and a use method thereof. Background technique [0002] Heat exchangers include air source heat pump water heaters and heating air conditioners, both of which are equipped with outdoor units, of which the condenser and compressor are the main components of the outdoor unit. The condenser is mainly composed of fins and copper tubes. The copper tubes are filled with cold medium, and the compressor connected to the copper tubes does work to compress the cold medium into high-temperature and high-pressure gas steam. The high-temperature and high-pressure gas steam passes through the heat exchanger connected to it or Heat exchange is performed when heating the indoor unit of the air conditioner, so that the temperature of the water in the water tank where the heat exchan...

AI Technical Summary

Problems solved by technology

[0004] The present invention mainly provides an ultra-low temperature air energy heat pump unit with simple structure, the condenser can be automatically defrosted, the defrosting effect is good, and the energy consumption is saved, and its use method solves the problems existing in the prior art. In the case of ultra-low temperature, the condenser cannot be defrosted normally, and the defrosting effect is poor. In severe cases, it will cause technical problems such as the air source heat pump water heater or heating air conditioner not working properly.
