Double-working condition liquid cold water unit

Abstract

The invention discloses a double-working condition liquid cold water unit which comprises a liquid ice making system arranged in a metal box body and an ice water storage box connected to the exterior of the metal box body. The double-working condition liquid cold water unit is characterized in that the liquid ice making system consists of a refrigeration compressor, an air-cooled condenser, a thermal expansion valve, an ice crystal device and a titanium pre-cooled heat exchanger which are sequentially connected by virtue of refrigerant pipes; the ice crystal device and the titanium pre-cooled heat exchanger are arranged in parallel; a distributor is arranged on a pipeline on which the refrigerant outlet of the thermal expansion valve is connected with the ice crystal device; and the distributor is connected with the ice crystal device by virtue of a capillary tube. The liquid ice making system is arranged in the metal box body, and the unit is compact in structure, small in occupied area and convenient to move; the ice crystal device and the titanium pre-cooled heat exchanger are arranged in parallel, so that the heat exchange efficiency is effectively improved, liquid ice is synchronously made, the ice output is rapid, and the energy consumption is reduced; and moreover, the thermal expansion valve and the distributor are utilized for throttling twice, so that liquid distribution is uniform, and the operating stability of the system is effectively improved.

Description

technical field [0001] The invention belongs to the field of refrigeration equipment, relates to liquid ice ice-making technology, and is specifically a dual-working-condition liquid ice-cooling water unit. Background technique [0002] Liquid ice is a new kind of ice that is different from traditional solid ice. It can be mixed with liquid to form a fluid ice slurry, and it can exist alone to form fine spherical particles that look like snow. It can achieve close and harmless contact with objects of various shapes, fill narrow spaces, have high heat exchange efficiency and fast cooling speed, and can be transported over long distances through conventional fluid pump delivery technology. It is widely used in food preservation, quality preservation, constant temperature heat transfer and constant temperature preservation and other fields. If the heat is exchanged through a heat exchanger, it can realize constant temperature heat exchange on the fluidized ice side; when used ...

Problems solved by technology

[0004] However, the existing liquid ice making equipment only uses ice crystals to cool the water to make ice. It takes a long time to reduce the water at normal temperature to the temperature of the ice-forming water -1°C. The cooling process consumes too much energy and the amount of ice produced Limited; the unit is fixedly installed and used. When used at a long distance, it is necessary to lay a long pipeline, which increases costs, cannot guarantee the quality of liquid ice, and has a poor cooling effect
