Embodiment Construction

[0009] like figure 1 As shown, the energy-saving cooler includes a refrigeration system and a liquid circulation circuit. The refrigeration system includes a compressor 7, an evaporative condenser, a dry filter 9, an expansion valve 10 and an evaporator 6 connected in sequence. The refrigeration system is located in the compressor The inlet and outlet pipelines of 7 are equipped with a low-pressure pressure control switch and a high-pressure pressure control switch. The liquid circulation circuit includes a liquid input pipeline 3 and a liquid return pipeline 4. The liquid input pipeline 3 is connected to the liquid inlet 1 of the cooler and the evaporator The input end of the liquid pipeline of 6, the liquid return pipeline 4 connects the liquid outlet 2 of the cooler and the output end of the liquid pipeline of the evaporator 6, and the evaporative condenser includes a blower fan 16, a dehydrator 17, which are arranged from top to bottom. The spray pipe 18, the first condens...

Abstract

The invention provides an energy-saving type cooling machine. By means of the energy-saving type cooling machine, the technical problem that existing cooling machines cannot meet the energy-saving requirement can be solved. The energy-saving type cooling machine comprises a refrigerating system and a liquid circulation loop. The refrigerating system comprises an evaporative condenser. The energy-saving type cooling machine is characterized in that a liquid input pipe is sequentially provided with a liquid temperature probe, a circulating pump and a first electric valve in the liquid flow direction; the cooling machine further comprises a second condenser coil pipe, a liquid bypass loop and an environment temperature probe; the second condenser coil pipe is arranged to be opposite to a first condenser coil pipe of the evaporative condenser and located between a spray pipe and a water pan of the evaporative condenser; the liquid bypass loop comprises a liquid input branch pipe and a liquid backflow branch pipe; the liquid input branch pipe connects the input end of the second condenser coil pipe with the position, located between the first electric valve and the circulating pump, ofthe liquid input pipe; the liquid backflow branch pipe is provided with a second electric valve and connects the output end of a second condenser with the position located between an evaporator and the first electric valve.

Description

technical field [0001] The invention relates to the technical field of liquid cooling equipment, in particular to an energy-saving cooler. Background technique [0002] The refrigeration system of some chillers uses evaporative condensers, which can effectively save cost and space compared with the combination of traditional condenser coils and cooling towers, but this type of chiller is always a In the cooling mode, if it is operated for a long time or all year round, the power is relatively high and the energy consumption is relatively high, which cannot meet the increasing demand for energy saving. Contents of the invention [0003] In view of the above problems, the present invention provides an energy-saving cooler, which can select different refrigeration modes for different working conditions, so as to solve the technical problem that the existing coolers cannot meet the energy-saving requirements. [0004] Its technical solution is as follows: an energy-saving coo...
