Problems solved by technology

For example, when the temperature of the air source heat pump unit is too low, frost will form on the surface of the outdoor heat exchanger, resulting in a decrease in the volumetric efficiency of the compressor, a decrease in the heating capacity, and sometimes even failure to start. The existing air source heat pump units usually use electric auxiliary heating. way to ensure the heating effect, and the overall operating performance of the unit decreases
Due to the characteristics of low energy flow density, intermittent and instability of solar energy, the heat pump system using solar energy as a heat source often requires a lar

Abstract

The invention discloses a heating air conditioning system for comprehensively utilizing solar energy and air energy and a running method, and belongs to the technical field of heat-pump heating air conditioners. The system consists of a solar thermal collector, a seasonal energy storage device, a night energy storage device, a first heat exchanger, a second heat exchanger, an air source heat-pump cold and hot water unit and a water source heat-pump hot water unit. The solar thermal collector is used for collecting solar energy for storing in the seasonal energy storage device; the air source heat-pump cold and hot water unit runs separately according to the air temperature situation of an outdoor environment, or constructs a double-stage coupled heat-pump system with the water source heat-pump hot water unit for running. During heat supply of the system, heat stored in the night energy storage device is used preferably, and energy stored in the seasonal energy storage device is replenished when heat is insufficient. By adopting the heating air conditioning system, efficient utilization of solar energy and environmental air heat energy is realized, and high economical efficiency is realized by accumulating heat and cold with off-peak electricity. The heating air conditioning system is suitable for regions where severe cold or cold regions are far away from a centralized heat supply heat network pipeline and the requirement on the atmospheric environment is strict.

Description

technical field [0001] The invention belongs to the technical field of heat pump heating and air conditioning. The invention relates to a heating and air conditioning system and an operating method that comprehensively utilizes solar energy and air energy, and is especially suitable for severe cold or cold areas that are far away from central heating and heating network pipelines and have strict requirements on the atmospheric environment. Civil buildings, hotels, office buildings, etc. Background technique [0002] At present, because central heating is limited by geographical location, it is difficult to realize central heating for extremely cold or particularly remote places in cold regions. If electric furnaces or electric floor heating are used for heating, it will lead to a transformation from high-grade energy to low-grade energy. waste; if gas-fired boilers, coal-fired boilers, etc. are used for heating, incomplete combustion of fuel will produce CO2, SO2 and other g...
