Description

Technical Field

[0001] The utility model belongs to the technical field of chillers, and particularly relates to an open chiller with a composite cold natural cold source. Background Art

[0002] At present, there are generally two ways to prepare cold water. One is a vapor compression cycle refrigeration unit, which can prepare low-temperature cold water, and the refrigerant is the refrigerant; the other is a cooling tower, which mainly uses the evaporation cooling method of water and can prepare high-temperature cold water, and the limit temperature of the cold water is the ambient wet bulb temperature.

[0003] In summary, at present, when using a refrigeration unit to prepare cold water, low-temperature cooling water can be obtained, but the cold source is a refrigerant, not a natural cold source, which is not environmentally friendly and consumes a large amount of electric energy; the cold source of the cooling tower is air and water, which belongs to a natural cold source, but the prepared cold water has a high temperature and its application range is limited.

[0005] An open chiller with a composite cold natural cold source includes a chiller body, a spray system, a cold water evaporation cooling device, an air inlet and an air outlet. The spray system evenly sprays spray water onto the cold water evaporation cooling device. An air-cooled heat exchange tube is arranged at the air inlet of the chiller body, and the air-cooled heat exchange tube is circularly connected with a cooling water evaporation cooling device through a cooling water circulation system.

The cooling water circulation pipeline is respectively connected with the cooling water inlet and the cooling water outlet and is connected with the cooling water evaporation cooling device to form a circular connection. A cooling water distributor is arranged below the cooling water inlet, a cooling water evaporation cooling device is arranged below the cooling water distributor, a cooling water tank is arranged below the cooling water evaporation cooling device, a cooling water outlet is arranged on the cooling water tank, and a cooling water circulation power component is arranged on the cooling water circulation pipeline.

[0011] Beneficial effects: The present utility model provides a composite cold natural cold source open-type chiller.

[0012] 1. By using natural cold sources, air and water, compared with the vapor compression cycle refrigeration unit using refrigerant, it is beneficial to environmental protection.

[0013] 2. By adopting the combination of evaporation cooling and air cooling, compared with the vapor compression cycle refrigeration unit using a compressor, the EER value is greatly improved, effectively saving electric energy.

[0014] 3. By adopting the combination of evaporation cooling and air cooling, compared with the cooling tower adopting the evaporation cooling method, the cold water temperature can be reduced below the wet bulb temperature of the ambient air, broadening the application range of the unit.
