Problems solved by technology

[0003] When the air conditioner is turned off at night, the heat of the indoor system cannot be effectively discharged, which will cause the exhaust temperature of the system compressor to rise. If the condensation pressure is too high, it will easily cause the overall cooling effect of the equipment to be poor, and the equipment will frequently malfunction and alarm. In addition, it is easy to cause the goods in the cabinet to deteriorate, and in severe cases, it will cause equipment damage, which makes the use of the built-in display cabinet a great safety hazard.

Abstract

The invention discloses a multistage heat exchange absorption type refrigeration and heat dissipation system for a built-in display cabinet. The multistage heat exchange absorption type refrigerationand heat dissipation system comprises a refrigerant circulation device and an absorption type refrigeration device, refrigerant circulation device comprises a compressor, a plate type heat exchanger,an electromagnetic valve, a throttling pressure reduction part and a first evaporator; the absorption type refrigeration device comprises a generator, a condenser, an evaporator, a first absorber anda liquid storage tank, the generator is connected with a second evaporator; the top of the generator is connected with the inlet of the condenser, and the outlet of the condenser is connected with theinlet of the second evaporator; a separator is further arranged on a pipeline connected with the generator and the condenser, and the second evaporator and the separator are correspondingly connectedwith the first absorber through pipelines. According to the multistage heat exchange absorption type refrigeration and heat dissipation system, the heat exchange between refrigerant and secondary refrigerant is realized in the plate type heat exchanger, the refrigerant circulation device is used for cooling the secondary refrigerant, so that the heat of the system can be transferred from the roomto the outside, and the energy consumption is reduced; and the problem that the refrigeration effect is poor is solved, the equipment refrigeration efficiency is improved, and the system failure rateis reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration systems, in particular to a multi-stage heat exchange absorption cooling and cooling system for built-in display cabinets. Background technique [0002] At present, most of the refrigeration systems of built-in display cabinets use air-cooled condensers, whose cooling efficiency is low, and the heat of the system is directly discharged indoors. When the indoor ambient temperature is high, especially in summer, due to the increase of indoor heat, the load of the indoor air conditioner will be increased, additional power consumption will be increased, and the use cost will be increased. [0003] When the air conditioner is turned off at night, the heat of the indoor system cannot be effectively discharged, which will cause the exhaust temperature of the system compressor to rise. If the condensation pressure is too high, it will easily cause the overall cooling effect of the equipment to be po...
