Embodiment Construction
[0038] The control method of the compound cold and heat source system will be further described below through the examples.
[0039] see figure 1 :
[0040] During the day:
[0041] 1. When the water in the solar collector water tank reaches 85°C, the water valves b and c are opened, and the water valves a and d are closed. The hot water in the solar collector water tank is injected into the upper part of the middle barrel through the water valve c, and the lower part of the middle barrel The cold water is preheated by the heat exchange coil and then returned to the solar collector water tank through the water valve b to be heated.
[0042] 2. When the water temperature of the solar collector water tank is lower than 40°C, the water valves b and c are closed so that the water temperature of the solar collector water tank can be maintained at an appropriate temperature.
[0043] 3. When the temperature of the refrigerant flowing out of the compressor is lower than 40°C, the ...

The invention relates to the field of air conditioners, in particular to a compound cold and heat source system for an air conditioner, and a control method of the compound cold and heat source system. The compound cold and heat source system comprises an air source and a solar energy; and used equipment comprises a compressor (1), an air cooler (2), a middle barrel (3), a heat exchange coil pipe (4), a solar heat collector water tank (5) and a solar heat collector panel (6). The heat exchange coil pipe (4) is arranged at the bottom of the middle barrel (3), and water therein is exchanged with water in the solar heat collector water tank (5) to store more heat. The compound cold and heat source system can be realized by the equipment easily purchased on the market, can reduce the use of a heat exchanger, and can prevent secondary pollution of hot water.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a composite cold and heat source system used in an air conditioner, and a control method for the composite cold and heat source system. Background technique [0002] In the field of air conditioning systems, saving energy is the general trend. The traditional air-conditioning system relies on electricity as the only energy input, and the heat generated by the air-conditioning system is diffused into the air, that is, the air is used as the cooling source. In order to save electric energy, various composite systems using multiple cold and heat sources have been proposed in the prior art. For example, Chinese patent publication CN101988775A discloses a composite cold and heat source system that utilizes ground source, air source and solar energy at the same time, and Chinese utility model patent CN202869082U discloses a composite system combining solar heat pump and photoelectricit...
