Problems solved by technology

However, in winter, the system often causes the evaporator of the heat pump to freeze due to the low temperature of seawater in rivers and lakes; or the evaporator freezes due to power outages and water outages, making the system unable to work normally, so the system cannot be widely promoted and used.

Abstract

A heat pump system by using water as energy source, includes an energy-collecting equipment, a second heat exchanger, an energy-exalting equipment, a first heat exchanger and a radiator connected in series. The energy-collecting equipment includes a circuit of a low-grade heat exchanger coil, a collector well and a diving pump inside the well in series. The energy-exalting equipment includes a circuit of an evaporation, two compressors, a condenser and a expansion valve in series, the said two compressors are connected in parallel. The radiator includes a circuit of an energy-inputting coil, a pump and several radiation fin in series. Inside the first and second heat exchanger, there is antifreeze. The system has a simple structure, which is easily to install and maintain, and can supply heat or cold to users normally in any case.

Description

technical field [0001] The present invention relates to a heat pump system for extracting water energy, in particular to a heat pump system for extracting energy from rivers, lakes, seas or groundwater. It converts low-grade heat energy into high-grade heat energy through heat pumps to achieve heating in winter, cooling in summer and daily supply of domestic hot water. the goal of. Background technique [0002] The Chinese Invention Patent No. ZL00123491.9 that the applicant of the present invention applied for earlier provides a liquid cold and heat source system that utilizes seawater in rivers, lakes, and lakes as energy for people, providing people with a pollution-free, floor-to-ceiling system that uses seawater, river water or river water as energy Small, cold and heat source system that can provide hot water for domestic use. However, in winter, the system often causes the evaporator of the heat pump to freeze due to the low temperature of seawater in rivers and lake...
