Embodiment

[0050] The embodiment of the present application provides a multifunctional cold storage refrigeration system with adjustable storage temperature. figure 1 For example.

[0051] A multifunctional cold storage refrigeration system with adjustable storage temperature is mainly composed of a regenerator 7, a bypass valve 8, a centrifugal compression-expansion integrated machine 2, a stage after-cooler 3, a water removing heat exchanger 4, and a fan 5. The regenerator 7 is arranged in the cold storage 1 and is connected to the centrifugal compression-expansion integrated machine 2. A bypass valve 8 is installed on the cold fluid side. The centrifugal compression-expansion integrated machine 2 and the post-stage heat exchanger 3 are used to remove water and heat The fan 5 is installed on the hot side of the water removal heat exchanger 4.

[0052] The working process of the present invention is as follows: the expanded low-temperature air enters the regenerator 7 to be reheated, a...

Abstract

The present application belongs to the technical field of refrigeration, and in particular relates to a refrigeration system for a cold storage. The supply air temperature of the existing cold storage depends on the evaporation temperature of the evaporator, which is inconvenient to adjust, and there is heat exchange loss. The application provides a refrigeration system for a cold storage, comprising a moisture removal component, a gas temperature adjustment component and a heat exchange component connected in sequence, the heat exchange component is arranged in the cold storage, and an impurity adsorption member is arranged in the moisture removal component. Dehumidification is completed outside the warehouse; no fan coil unit is required, and the air is directly supplied to the cold storage, and directly mixed with the gas in the storage to speed up heat transfer and increase the cooling rate.

Description

technical field [0001] The present application belongs to the technical field of refrigeration, and in particular relates to a refrigeration system for a cold storage. Background technique [0002] Cold storage generally uses artificial means to create an environment different from outdoor temperature or humidity. It is a constant temperature and humidity storage equipment used to store food, chemicals, medicine, vaccines, scientific experiments and other items. Generally, the cold storage is mostly refrigerated by a refrigerator, and the refrigerant with a lower gasification temperature (ammonia, freon, etc.) is used as a coolant to evaporate under the condition of low pressure and mechanical control, and absorb the heat in the storage, so as to achieve cooling cooling purpose. The most commonly used is vapor compression refrigeration, which is mainly composed of compressor, condenser, throttle valve and evaporator. [0003] Usually divided into direct cooling and indirec...
