Combined solar refrigerating equipment

Abstract

The composite solar refrigerating equipment mainly includes generator, condenser, throttle valve, evaporator, absorber, solution heat exchanger, compressor, solar heat collector, water pump, valve and solution pump. The solar heat collector, generator and water pump are formed into circulation of solar heat-collecting system, the solution heat exchanger is connected with generator and absorber and formed into the circulation of concentration solution, and the compressor is connected with generator, condenser, throttle valve, evaporator and absorb and formed into the circulation system of compression refrigeration. Said equipment can be operated all weather. Its working efficiency is high.

Description

Technical field: [0001] The invention relates to a composite solar cooling device, in particular to a composite solar cooling device which is not limited by weather changes and is jointly driven by solar energy and electric energy, and belongs to the technical fields of building environment and equipment engineering and refrigeration engineering. Background technique: [0002] Most refrigeration and air-conditioning devices use synthetic substances that are harmful to the environment (with greenhouse effect and ozone layer destruction) as working fluids, and are driven by high-grade energy such as electricity. With the increasing popularization of refrigeration and air-conditioning devices, energy-saving and environmental protection issues caused by refrigeration and air-conditioning have increasingly become the focus of attention. Therefore, in the field of refrigeration and air conditioning, the use of environmentally friendly working fluids (such as natural working fluids...

Problems solved by technology

Most of the general solar refrigeration and air-conditioning devices simply adopt absorption or adsorption refrigeration methods, which have the disadvantages of complex structure, high manufacturing cost, low operating efficiency, and the need for auxiliary heating devices, which greatly hinders the promotion of solar energy in the refrigeration and air-conditioning industry. and application

[0003] In the existing technology, the patent number is 93119264.1, and the patent named "Hot Water Two-Stage Absorption Refrigeration Machine" uses solar energy as the heat source, "including a built-in condenser, high-pressure generator, low-pressure generator and high-pressure absorption The high-pressure cylinder of the generator, a low-pressure cylinder with a built-in low-pressure generator and evaporator, and high and low-pressure heat exchangers, are connected through corresponding pipelines and shielded circulation pumps to form a two-stage absorption cycle refrigeration system, and the structure is very complicated.

The patent number is 00109336.3, and the patent title is "A Solar Absorption Air Conditioning System". Although the absorption refrigeration system uses a single-effect method, it requires a complex set of auxiliary heat sources and heat storage devices

The above shortcomings have greatly hindered the promotion and application of solar energy in the refrigeration and air-conditioning industry
