Product Detail
REVERSE CARNOT CYCLE THEORY
1. The refrigerant suddenly drops to -20*C after the pressure is released. When the ultra-low temperature liquid refrigerant enters the absorption evaporator, it encounters about 20*C air passing through the air heat transfer (temperature difference: 40'C), and the ultra-low temperature refrigerant absorbs After the heat to the air, the temperature rises to 20C;
2. The refrigerant with a temperature of 20C enters the high-temperature compressor and is heated and pressurized, and then becomes a high-temperature high-pressure 80C gas-state discharge compressor to enter the heat exchanger.
3. The temperature at 80C vaporized refrigerant transfers heat energy to the low-temperature cold water in the heat exchanger, so that it becomes about 60C. The domestic hot water is pumped into the insulated water tank for storage and use, and the high-temperature refrigerant is released after heat release. It becomes a high pressure liquid.
4. The high-pressure liquid refrigerant is throttled and depressurized by the expansion valve and then becomes a low-pressure liquid state, so that it enters the evaporator to absorb heat again;
5. According to the reverse Carnot cycle principle, the compressor is continuously and repeatedly cycled. The whole process is the process of heat transfer. As long as the compressor is operated with one degree of electricity, it can absorb from the air to the equivalent of 3 degrees to 6 degrees. The heat generated is transferred to the water, and the energy saving and safety effects are very obvious.
