Total heat source heat pump system

Abstract

The invention provides a total heat source heat pump system, and relates to the field of heat pumps. The total heat source heat pump system comprises a compressor, a four-way valve, a condenser, a liquid storage device, an economizer, a throttling valve, an evaporator, a gas-liquid separator, an economizer throttling valve, an energy module, a one-way valve and a solution pump. The energy module of the total heat source heat pump system adopts a large-flow small-temperature-difference design, the temperature difference between a solution and air is small, frosting is not prone to occurring, frequent defrosting is not needed, the energy consumption is small, the efficiency is high, the surface of a heat exchanger is made of graphene coating, and the heat exchange efficiency is high; and the surface density is high, water is not easy to stick, and frosting is not easy, the evaporator adopts an overflow type design, a refrigerant and the solution are subjected to sufficient heat exchange, the heat exchanger is fully utilized, the evaporation is uniform, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to an all heat source heat pump system. Background technique [0002] The smog in the northern winter heating season has made people pay more attention to the pollution-free heat pump technology, which has gradually been recognized by all walks of life due to its inherent advantages of energy saving and environmental protection. [0003] At present, there are mainly two types of heat pump heating technologies that are widely used: water (ground) source heat pump technology: this technology has been widely promoted in the past few years because of its high efficiency and environmental protection. However, the large-scale promotion of water source heat pumps and the irrational use of water resources have led to the extreme waste of groundwater. In recent years, some areas have been stopped, and even wells have been closed. Ground source heat pumps require a large investment and ar...
