Finned solar heat pump evaporator device

Abstract

The invention discloses a finned solar heat pump evaporator device, comprising a tank. Two compressor sets (not limited to two, one set or other sets being available) and a liquid reservoir are mounted on an inner bottom surface of the tank, an outlet end of each compressor is connected with a condenser (or a heating coil), an outlet end of the liquid reservoir is connected with a filter, an outlet end of the filter is provided with an expansion valve, an evaporator fan is mounted on the side of the tank, a transparent mesh cover is arranged outside the evaporator fan, a solar evaporator assembly is mounted at the top of the tank, an organic glass cover of high transparency is arranged outside the evaporator assembly, the evaporator assembly is composed of coils and evaporating fins, the coils are of multilayer frame structure, and two coil sets form a closed tower structure. The two coil sets and the evaporating fins form the tower structure, and the surface of each fin is coated ith a heat-absorbing coating; it is possible to absorb solar power at various angle in various directions; the use of multilayer wavy evaporating fins effectively increases heat absorption area; the device is small in floor area, high in operating efficiency, energy-efficient and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a finned solar heat pump evaporator device. Background technique [0002] At present, emerging renewable energy technologies such as solar energy and wind energy have been widely used in industrial and agricultural production. Solar energy resources are abundant, environmental protection and sanitation, solar energy resources are very abundant in many areas of our country, but the utilization rate is not high. Heat pump technology is a new type of energy-saving cooling and heating technology. The heating system mainly based on solar direct heating and supplemented by air source heat pump has attracted more and more attention. Because the sun's azimuth and sun's altitude change with seasons and daytime changes, it causes problems such as unstable heating and low solar energy utilization efficiency. Contents of the invention [0003] The purpose of the present ...
