Description

Energy storage radiation trinity air conditioning unit

technical field

The invention relates to the technical field of refrigeration, and more specifically relates to an energy-storage radiation type trinity air-conditioning unit.

Background technique

In existing air-conditioning systems, the heat of condensation is directly or indirectly discharged into the atmosphere. Condensed heat is continuously discharged into the atmosphere, which is like “adding fuel to the fire” in a hot summer, which further increases the temperature in the city and enhances the city’s heat island effect, while the increase in ambient air temperature deteriorates the operating conditions of the air conditioner. The COP of the air conditioner is reduced and the operating efficiency is low. Therefore, in order to maintain people's comfortable conditions, the air conditioner needs to be operated for a longer time and with a greater load, thereby consuming more electric energy and causing a vicious circle.

On the other hand, at present, room cooling is mainly through split air conditioners, heating is through heat pump air conditioners, electric heaters or centralized boiler heating, etc., hot water is obtained through water heaters (gas, electricity, solar energy) or water heaters, but the above are basically all It is a single independent device, and there are some problems of energy saving and environmental protection. At present, some heat pump water heaters have been launched on the market. The operating efficiency of this kind of heat pump water heater using air conditioners to heat domestic hot water is much higher than that of traditional water heaters. However, its load varies greatly. The reliability of operation in this mode has not been very good. Moreover, it can only produce heating or domestic hot water alone, and the two modes of heating and domestic hot water cannot be performed at the same time.

In cold regions, due to the defrosting problem, the use of ordinary heat pump air-conditioning units is greatly restricted. Users can only use coal and electricity to directly extract heat sources for heating. Obviously, this way of energy utilization is unreasonable and wastes energy. .
