Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:

[0015] Such as figure 1 As shown, the present invention provides a kind of ice machine unit ammonia cooling system, and its ice machine unit has 4 groups in parallel,

[0016] 1) The ice machine unit is provided with an economizer for throttling and cooling, the inlet of the economizer is connected to the liquid reservoir module, and the outlet of the economizer is connected to the ammonia-cooled liquefier;

[0017] 2) The inlet of the oil cooler is connected to the bottom of the ammonia reservoir module, and the outlet is connected to the top of the reservoir module.

[0018] The outlet pipe 1 of the oil cooler converges to a main pipe 2 connected to the top of the reservoir module, wherein the outlet pipe 1 of the oil cooler is connected to the main pipe 2 obliquely in the direction of flow.

[0019] According to the actual demand, mu...

Abstract

The invention belongs to the field of liquid ammonia cooling, and particularly relates to an energy-saving ammonia cooling system of a cooling machine unit. The ammonia cooling system is characterized in that 1), a throttling and cooling economizer is arranged in the cooling machine unit, an inlet of the economizer is connected to a liquid storage device module, and an outlet of the economizer is connected to an ammonia cooling liquefier; and 2), an inlet of an oil cooler is connected to the bottom of the ammonia liquid storage device module, and an outlet of the oil cooler is connected with the top of the liquid storage device module. Compared with a traditional water cooling system, the ammonia cooling system of the cooling machine unit is high in cooling efficiency and better in cooling effect.

Description

technical field [0001] The invention belongs to the field of liquid ammonia refrigeration, and in particular relates to an energy-saving ammonia cooling system for an ice machine unit. Background technique [0002] In the refrigeration cycle, the evaporator, compressor, evaporative cooler, and throttle valve are four essential components: Evaporator: The refrigerant evaporates at the evaporation temperature under the evaporation pressure and absorbs the heat of the cooled substance to achieve refrigeration , is a device that transports cold energy outward. Compressor: It is the heart of the system, which plays the role of transporting refrigerant vapor, and at the same time ensures that the evaporator operates under the evaporating pressure and the evaporative cooler operates under the condensing pressure. It is a device that inputs work. Evaporative cooler: The refrigerant vapor transfers the heat absorbed from the evaporator and the heat transformed by the compression wor...
