A refrigeration system condensation heat stepless heat recovery device and refrigeration system

Abstract

The invention discloses a condensation heat and electrodeless heat recovery device of a refrigeration system, which comprises a fan, an air cooling condenser and a controller, wherein the fan and the air cooling condenser are mounted in a to-be-heat air channel; a refrigerant inlet of the air cooling condenser is connected with a compressor outlet of the refrigeration system; a refrigerant outlet of the air cooling condenser is connected with a compressor inlet of the refrigeration system; and the controller controls a flow of air entering the air cooling condenser by adjusting a rotating speed of the fan, so that a temperature of the to-be-heat air is adjusted. The heat recovery device can be connected into any refrigeration system conveniently, can utilize condensation heat of the refrigeration system effectively, can achieve quantized control of the condensation heat by controlling the rotating speed of the fan, and cannot cause any hidden danger to the connected refrigeration system. In addition, the heat recovery device is simple to control; a flow of a refrigerant of the refrigeration system is not required to be adjusted when the heat is adjusted; the stability of the system is higher; the temperature is controlled more accurately; and a dead zone cannot exist.
