Abstract

The invention relates to a solar heat pump and power heat pipe compound system. The system comprises a heat pump system consisting of a compressor, a water-cooling condenser, an evaporator, a throttle mechanism, an indoor air-cooling heat exchanger, an outdoor air-cooling heat exchanger, an electromagnetic valve and a pipeline which are connected with one another; a heat pipe evaporation pipe and a heat pipe return pipe are arranged; one end of the heat pipe evaporation pipe is communicated with an inlet of the water-cooling condenser, and the other end of the heat pipe evaporation pipe is communicated with an outlet of the evaporator; the heat pipe evaporation pipe is provided with the electromagnetic valve; one end of the heat pipe return pipe is communicated with an outlet of the water-cooling condenser, and the other end of the heat pipe return pipe is communicated with an inlet of the evaporator; the heat pipe return pipe is provided with a return medium pump and the electromagnetic valve; and the heat pipe evaporation pipe, the water-cooling condenser, the heat pipe return pipe and the evaporator form an annular power loop. In the system, the solar heat pump is combined with the power heat pipe according to the operation mechanisms of the two, so that various functions are realized through switching between the heat pump and the heat pipe; and the practicability of the system is improved, the conventional energy consumption is reduced, and the comprehensive efficiency of the system is also improved.

Description

Solar heat pump and power heat pipe composite system technical field The invention belongs to the field of solar energy application and relates to a solar heat pump heat pipe system. technical background The energy issue is the primary issue facing the social and economic development today. Energy shortages and inefficient use of energy severely constrain economic development. Solar energy has become an important substitute for traditional energy because of its renewable energy and environmental protection characteristics. Solar heat pump technology is a utilization method that combines solar light-to-heat conversion with a heat pump cycle system. According to relevant research, compared with the traditional air-cooled heat pump, the heat pump performance of the heat pump system is better when solar radiation is used as the heat source. However, during the operation of the solar heat pump, the compression process of the compressor needs to consume more electric energy,...
