specific Embodiment approach

[0019] Such as figure 1 As shown, the refrigerant absorbs solar energy through the solar heat collector (9), enters the phase change heat storage device (12), the compressor (13), the hot water storage tank (6), and the electronic expansion valve (8) in sequence to complete a Close the loop, and finally store the solar energy in the hot water storage tank (6). The water body of the low-level cold and heat source is pumped into the automatic decontamination device (2) by the water pump (1), and the dirt is removed; the filtered water enters the heat exchanger (3) to exchange heat with the intermediate water. Driven by the intermediate water circulating pump (5), the intermediate water enters the heat exchanger (3) to extract the heat from the low-level cold and heat source water body, and then is further heated by the hot water storage tank (6), and then enters the water source heat pump unit (14) The evaporator in) releases heat to complete a cycle. The water source heat pump...

Abstract

The invention discloses an efficient direct-expansion solar heat pump and water source heat pump coupled heat supplying system. The system is characterized in that the angle of a solar heat collector is adjusted in real time through a full-automatic solar tracking device, therefore, sunlight vertically irradiates the solar heat collector, and maximum solar radiation energy is achieved; by arranging a phase change heat storage device on a direct-expansion solar heat pump system, the evaporating temperature of a refrigerating agent is kept within a certain range, and then influences of changes of the solar radiation intensity to the system stability are greatly reduced; solar energy is stored through a heat storage water tank, intermediate water is preheated through the heat storage water tank, therefore, heat obtained through the direct-expansion solar heat pump system is effectively transmitted to a user, and then effective coupling of a solar heat collection and heat storage technology and a water source heat pump is completed. The efficient direct-expansion solar heat pump and water source heat pump coupled heat supplying system has the advantages that the problems of intermittency and unstability of solar energy sources are effectively solved, it is guaranteed that the system can stably supply energy, the system performance is significantly improved, and high efficiency and environmental friendliness are achieved.

Description

Technical field [0001] The invention belongs to the technical field of energy utilization, and relates to a high-efficiency direct expansion solar heat pump and a water source heat pump coupling heating system. Background technique [0002] The utilization of cold and heat sources such as sewage, seawater, and groundwater can alleviate the current energy shortage situation. It has good energy saving, environmental protection and economic benefits. It will save increasingly scarce freshwater resources, open up new areas for energy utilization, and provide comprehensive Full use of water resources provides a new idea. Solar energy is inexhaustible and inexhaustible. It is a clean renewable energy source. my country has a vast territory and abundant solar energy resources. Solar radiation is dispersive. A collector is a device that collects solar energy and converts it into heat. The performance of the collector directly affects the quality of the solar energy collected. At the s...
