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...
