Solar energy and air energy double-source combined heat supply and refrigerating equipment

Abstract

The invention discloses solar energy and air energy double-source combined heat supply and refrigerating equipment. The solar energy and air energy double-source combined heat supply and refrigerating equipment comprises a solar heat collecting plate. The outer side of the solar heat collecting plate is sleeved with a heat preservation glass cover. Each of the front side and the rear side of the heat preservation glass cover is provided with an air convection hole. A solar heat collecting pipe is laid on the upper surface of the solar heat collecting plate and filled with a refrigerant. An outlet of the solar heat collecting pipe is connected with an inlet of a heat pump compressor through a pipeline. An outlet of the heat pump compressor is connected with a circulation pipeline. The heat pump compressor is connected with an automatic control system. The circulation pipeline is arranged on the outer surface of a heat exchange water tank. An outlet of the circulation pipeline is connected with an inlet of the solar heat collecting pipe. The heat pump compressor is provided with a four-way reversing valve, and an electric heating pipe is further arranged on the outer surface of the heat exchange water tank. Heat supply and refrigeration can be achieved through solar energy and air energy, energy saving and environment friendliness are achieved, and heat supply and refrigeration are integrated.

Description

technical field [0001] The invention relates to the technical field of heating and cooling, in particular to a dual-source heating and cooling device combining solar energy and air energy. Background technique [0002] As the country's environmental protection requirements become more and more stringent, air pollution and smog become more and more serious, the country will gradually phase out small coal-fired boilers for heating. For a long time, industrial coal combustion has been the cause of air pollution and smog in many regions The main culprit. This point has also become the consensus of the whole society. At present, coal-fired boilers are mainly used for heating in the northern region, and the existing heating and cooling are set separately. Radiators are generally used for heating, and air conditioners are used for cooling. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet.
