The embodiment of the application discloses an energy-saving air-cooled water chiller.

Referring to fig. 1, the energy-saving air-cooled water chiller comprises a case 1, a partition plate 2 is bolted at the middle height position of the case 1, a heat dissipation cavity 3 is formed in the space above the partition plate 2 of the case 1, and a condensation cavity 4 is formed in the space below the partition plate 2 of the case 1. The compressor 5, the condenser 6, the restrictor 7 and the evaporator 8 which are sequentially communicated are fixed in the case 1, the compressor 5 and the condenser 6 are positioned in the heat dissipation cavity 3, and the restrictor 7 and the evaporator 8 are positioned in the condensation cavity 4. Since the compressor 5 and the condenser 6 release heat during operation and the evaporator 8 absorbs heat during operation, the partition plate 2 reduces the heat exchange between the heat dissipation chamber 3 and the condensation chamber 4, so that the temperature of the condensation chamber 4 is kept low. A condensing fan 9 is also installed on the top of the cabinet 1 to bring heat generated in the heat dissipation chamber 3 into the air.

A water tank 10 containing cooling water is fixed in the condensation chamber 4 by bolts, and the evaporator 8 is located in the water tank 10. The water tank 10 is communicated with a water inlet pipe 11 and a water outlet pipe 12, and the water inlet pipe 11 and the water outlet pipe 12 both penetrate out of the case 1. One end of the water inlet pipe 11, which is positioned at the outer side of the case 1, is communicated with a cooling coil 13, and a water pump 14 is installed between the water outlet pipe 12 and the water tank 10 and used for driving cooling water to circularly flow.
