Solar heat pump system utilizing microchannel loop heat pipe

Abstract

The invention discloses a solar heat pump system utilizing a microchannel loop heat pipe. The system comprises a microchannel loop heat pipe module, a heat pump module and a water tank used for connecting the microchannel loop heat pipe module with the heat pump module. The microchannel loop heat pipe module comprises an evaporation end, a heat insulation end and a condensation end. The evaporation end, the heat insulation end and the condensation end are sequentially connected to form a loop. The condensation end is arranged in the water tank. The heat pump module comprises an evaporator, a compressor and a condenser. The evaporator, the compressor and the condenser are sequentially connected through a pipeline to form a loop. The pipeline is provided with a reversing valve and a throttling valve. The cross section of a microchannel of the evaporation end and the cross section of a microchannel of the condensation end are in a circular shape. Grooves are formed in the microchannel of the evaporation end and the microchannel of the condensation end respectively. The solar heat pump system utilizing the microchannel loop heat pipe is simple in structure and high in overall efficiency.

Description

technical field [0001] The invention relates to the technical field of solar energy saving, in particular to a solar heat pump system using a microchannel loop heat pipe. Background technique [0002] Solar energy is valued by people for its inexhaustible, safe, non-transportable, clean and non-polluting characteristics. The solar heat pump system consumes a part of high-grade energy (such as electric energy) at the cost of consuming part of the high-grade energy (such as electric energy). Through the thermal cycle, the solar radiation that cannot be directly used The thermal energy is transferred to the water, which in turn is available to us. When the sunlight is sufficient, the use of solar energy to produce hot water does not need to consume much electricity, which can meet people's daily needs and even be used in other industries, truly achieving energy conservation and environmental protection. [0003] However, since the rainy weather in most parts of our country is ...
