摘要
The utility model relates to the field of power engineering, is designed to convert low-grade heat of water bodies or streams into useful high-potential heat, and can be used for year-round heat supply of buildings.;The objective of the proposed utility model is to increase the efficiency of heat removal from the aquatic environment through the use of heat of crystallization of water.;The technical result of the proposed utility model is to increase the available thermal resource of a reservoir or watercourse, soften the requirements for the minimum temperature and volume of a low-potential heat source, increase the density of the heat flow between the aqueous medium and the heat carrier, and reduce the weight and size characteristics of the water-heat carrier heat exchanger.;A heat pump installation using low potential heat of the aquatic environment contains a vapor compression heat pump with a low-temperature coolant circuit, which includes a heat exchanger-evaporator coolant-freon, a water-coolant heat exchanger located in a pond or watercourse and representing a round pipe attached to the base in the form of a frame or mesh the cross-section through which the coolant, the circulation pump and the expansion tank circulate, while the pipe is made of elastic material and the low-temperature coolant circuit also includes at least one controlled valve for shutting off the coolant flow, while the expansion tank is connected to the circuit in the section along the flow of the coolant between the valve and the circulation pump, and the water-coolant heat exchanger is on the circuit section along the course of the flow coolant between the circulation pump and the valve.
