Description

Technical field [0001] The invention belongs to air processing equipment in the field of HVAC, in particular to a semi-press-in evaporative cooling multi-temperature chiller and its air conditioning device. Background technique [0002] With the gradual maturity of water evaporative refrigeration technology, evaporative refrigeration technology has been used in air-conditioning refrigeration systems in dry areas. Because dry air can evaporate refrigeration technology has huge energy saving and environmental protection advantages, it is used in air-conditioning systems. The maximum use of dry air for cooling is conducive to building energy saving. The existing evaporative cooling water supply device mainly uses outdoor dry fresh air to produce cold water. The cold water temperature theoretically approaches the dew point temperature of the fresh air, and a single cold water is output as the cooling medium. In this indirect evaporative cooling device , Air and water exchange heat a...

AI Technical Summary

Problems solved by technology

In the existing evaporative cooling water supply device, the outdoor dry fresh air is mainly used to produce cold water. The temperature of the cold water is theoretically close to the dew point temperature of the fresh air, and a single cold water is output as the cooling medium. In this indirect evaporative refrigeration device , air and water exchange heat and mass. In order to reduce the outlet temperature of cold water and reduce the irreversible heat exchange loss in the heat exchange process, the heat exchange area of ​​heat exchange devices (such as fillers, surface heat exchangers, etc.) is usually relatively large. This has caused problems such as the height of the evaporative cooling water supply device is too high, the floor area is too large, the noise of the exhaust fan is too large, and it is difficult to coordinate with the building.
