Abstract

The invention discloses a direct expansion type solar heat pump air conditioning system. The direct expansion type solar heat pump air conditioning system is mainly composed of a set of direct expansion type solar heat pump system, a set of air source heat pump system and a heat storage device and particularly comprises an outdoor condenser, a liquid storage pot, a filter, a capillary restriction choke, an indoor air-cooled heat exchanger, a water-cooled heat exchanger, six valves, a compressor, a four-way makeshift valve, a solar thermal collector and a phase-change heat storage device. The solar heat pump air conditioning system with the phase-change heat storage device is connected with the outdoor condenser in parallel, hot water and hot air can be provided in winter, and normal air conditioning refrigeration can be achieved in summer. The heat storage device and a compressor protecting device are integrated, redundant solar energy can be stored to be used at night or in rainy days, inlet temperature of the compressor can be kept at a certain value by overcoming environment influence, thermal performance is improved, service life of the compressor is prolonged, the structure is simple, energy is saved, and the environment is protected.

Description

Technical field [0001] The invention relates to a solar photothermal system, in particular to a direct expansion solar heat pump air conditioning system in which a phase change thermal storage device is applied to an air conditioner and a direct expansion solar heat pump, and belongs to the technical field of energy heating and air conditioning. technical background [0002] Energy and environmental issues have become one of the most focused issues in today's society. In recent years, with the rapid development of my country's construction industry, the energy consumption of heating and air conditioning in buildings has continued to expand. In developed countries, building energy consumption accounts for 25% to 40% of total energy consumption, and in my country it accounts for nearly 1 / 3 of total social energy consumption. In building energy consumption, the main parts are air conditioning energy consumption and hot water energy consumption, accounting for about 24% and 17%...
