Abstract

The present invention relates to a directly-expanded type solar heat pump air conditioning and water-heating system, the directly-expanded type solar heat pump and ice cold-storage air conditioner are combined organically, and it is mainly formed from solar heat collector/evaporator, compressor, condenser, electronic expansion valve, four-way reverse valve, heat water storage tank, hot water tank, air conditioner tail end cover and system control component. The solar heat collector/evaporator adopts the plate type heat collector which has no cover plate and whose bottom is heat insulated and whose surface is coated with solar spectrum absorbing material, and the energy storage device adopts a closed pressure-bearing heat storage water tank whose interior is equipped with high-effective heat exchange equipment which can store heat in winter and can store ice in summer.

Description

Technical field: [0001] The invention relates to a solar light and heat utilization system, in particular to a direct expansion solar heat pump air conditioner and hot water system, which belongs to the technical field of energy heating and air conditioning. Background technique: [0002] 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. According to statistics, my country's building energy consumption accounts for about 1 / 4 of the country's total energy consumption, ranking first in energy consumption. Energy consumption has not only exacerbated the increasing shortage and depletion of fossil fuels, but also seriously polluted the environment. The best way to meet the ever-increasing building energy demand without affecting the energy demand of other sectors or exacerbating the already serious pollution situation is to implement building energy cons...
