The water circulation cooling and heating all-in-one machine consists of a water tank, a cooling and heating system, etc. the cooling and heating all-in-one machine system is independent and the heating system has a water tank. The cold and heating body tie-in pumping function requires the hot water system to actively replenish water through the water tank of the cold water system. This function can also be completed. The working principle of the equipment is as follows:

The cold and hot integrated machine is composed of a hot water system and a cold water system. The hot water system is an electric heating water temperature machine, which can complete the active temperature control of the heated object; The cold water system is a chiller, which can actively control the temperature of the cooled objects.

The hot water system replenishes water to the hot water tank through the water replenishment solenoid valve of the water chiller tank, and the cold water system also replenishes water through the water chiller tank; The hot water tank adopts the high and low liquid level device. When the hot water tank is at the low liquid level, the cold and hot integrated machine has an alarm prompt. The solenoid valve between the hot water tank and the cold water tank is opened, and the cold water tank replenishes water to and from the hot water tank. When the hot water tank replenishes water to the high liquid level, the solenoid valve is closed, completing the active water replenishment function of the hot water tank.

When the temperature control host needs to be heated, the thermal system of the cold and hot integrated machine is enabled. The water temperature machine equipment uses electricity as the heat source and water as the heat carrier, and uses the circulating pump to forcibly cycle, transfer the heat energy to the heating equipment, and then come back for continuous heating. In this way, the continuous increase of heat is completed, so that the temperature of the heated object increases, reaching the process requirements of heating constant temperature.

When the temperature control object needs to be cooled, the compressor works through electric energy to compress the refrigerant in the system into a high-temperature and high-pressure gas, which enters the condenser from the high-pressure exhaust port. The condenser is equipped with a dispersing hot air fan. After forced air flow, the refrigerant in the system is cooled into a liquid at room temperature and high pressure. The refrigerant passes through the filter to filter out the impurities and moisture in the system, passes through the throttle valve, and enters the evaporator, and the refrigerant becomes a low-temperature and low-pressure gas, Absorb the heat of circulating water to achieve the purpose of refrigeration, and the refrigerant returns to the compressor through the suction port of the compressor for the next cycle; The cooled cold water is delivered to the cooled object for cooling through the circulating pump, and then comes back for continuous cooling. In this cycle, the temperature of the cooled object decreases to meet the process requirements of cooling and constant temperature.

When the heating (refrigeration) of the host machine is completed, the water circulating pump of the hot water system of the cold and hot all-in-one machine will pump the hot water back to the hot water tank; Similarly, the circulating pump of the cold water system will pump the cold water back to the cold water tank. This is the whole process of temperature control of the hot and cold machine.
