Cooling-water machine with dual-temperature double-control system structure

Abstract

The invention discloses a cooling-water machine with a dual-temperature double-control system structure and belongs to the technical field of cooling-water machines. The cooling-water machine comprises a water bucket, a second cool-heat-exchanger, a water receiver, a first cool-heat-exchanger, a compressor and a condenser; through additionally arranging an electromagnetic valve, the first cool-heat-exchanger and the second cool-heat-exchanger, on and off of the electromagnetic valve are intelligently controlled through software; the temperature of exhaust gas of the compressor is utilized andis conducted to water through the first cool-heat-exchanger to heat and output, and one path of high temperature water and one path of low temperature water are outputted on the working condition of not increasing any load of the cooling-water machine system; at the same time, as the heat of the exhaust gas of the compressor is absorbed by low temperature water, and it is equivalent to increasingthe condensing area of the cooling-water machine during the refrigerating process, the refrigerating efficiency of the cooling-water machine system is greatly improved; and in a dual-temperature double-control system realizing the equal effect, the cooling-water machine replaces a thermal fuse, saves energy, greatly improves the energy-saving efficiency, and is safer to use and high in practicality.

Description

technical field [0001] The invention relates to the technical field of water chillers, in particular to a water chiller with a dual-temperature dual-control system structure. Background technique [0002] Chiller is a kind of water cooling equipment, which can provide constant temperature, constant flow and constant pressure cooling equipment. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, cool the water through the chiller refrigeration system, and then have a water pump inside the machine to inject low-temperature frozen water into the equipment that needs to be cooled, and the chilled water will cool the water inside the machine. The heat is taken away, and the high-temperature hot water is returned to the water tank to cool down again, so that the cooling is circulated and exchanged to achieve the effect of cooling the equipment. [0003] The existing dual-temperature dual-control system structure of the ...

Problems solved by technology

[0003] The existing dual-temperature dual-control system structure of the chiller uses a heater to heat and output hot water, and the heating pipe is powered by 220V high voltage, which is unsafe and has many faults

The other channel uses a compressor to compress and refrigerate to output low-temperature water, and the two channels of water return to a bucket at the same time. This type of dual-temperature output chiller system increases the cooling load of the chiller due to the addition of a heater on the water channel. At the same time, the whole machine The power will increase, resulting in low efficiency
