Description

Cold and heat exchange energy saving system

A cold and heat exchange energy-saving system. This creation especially refers to an air-conditioning system that can store thermal energy, reduce the load of the ice water host, and discharge the waste through the cooling water tower when air-conditioning is not required in winter, so as to achieve energy-saving and power-saving effects.

In general air-conditioning systems, in the process of cooling and dissipating the refrigerant in a high-pressure and high-temperature gaseous state to a liquid state, the heat is directly dissipated in the atmosphere. This not only fails to properly use the heat, but also causes air pollution, and the cooling water evaporates and dissipates heat. The heat of refrigerant vapor also increases the waste of water resources. Therefore, the current industry has developed an effective heat recovery of the heat generated by the high-pressure and high-temperature refrigerant vapor in the air conditioning system to supply the heat source of hot water. This not only saves energy and avoids air pollution, but the heat recovery is widely used, such as in life The most basic personal body washing, and even the popular heated swimming pools, SPA hot pools, hot water baths in hotels and restaurants, etc. However, the design of heat recovery devices (such as heat exchangers) with conventional technology is accompanied by When the refrigerant load of the air-conditioning system is fully loaded, a large amount of heat energy is absorbed from the condenser and converted into hot water of the required temperature for use. Under this design, the refrigerant load of the air-conditioning system is reduced or even no load. The heat energy is relatively reduced and cannot meet the heating demand of hot water. In other words, not only must hot water and air-conditioning be produced at the same time, but the load capacity of the refrigerant cannot be controlled. Moreover, the existing air-conditioning system only has a single or dual function, such as It has only air-conditioning function, only heating function, cooling/heating function, etc. At the same time, the existing air-conditioning system cannot efficiently use energy. For example, when using air-conditioning, the hot air is directly discharged into the atmosphere, which not only causes energy waste, It also causes an increase in the temperature effect of the city.

In view of the above-mentioned problems, this creator is based on years of experience in related industries to research and modify systems and devices that have both air conditioning functions and provide hot water at the same time; for this reason, the main purpose of this creation is in winter Provided is a cold-heat exchange energy-saving system that can store heat energy and discharge waste cold to achieve energy-saving effects when the demand for cooling and air conditioning is not high.
