Embodiment

[0053] like figure 1 As shown, a refrigeration system combining adsorption and vapor compression includes a compressor 1, an evaporative cooler 2, a throttle valve 3, and an evaporator 4 that are sequentially connected to form a vapor compression refrigeration cycle, and also include sequentially connected to form a first adsorption cycle. The first adsorption bed 51, the first adsorption condenser 6161, and the first adsorption evaporator 71, the condensation heat released by the evaporative cooler 2 provides heat for the first adsorption bed 51.

[0054] The first refrigerant circulates in the vapor compression refrigeration cycle connected by the compressor 1, the evaporative cooler 2, the throttle valve 3 and the evaporator 4, and the second refrigerant circulates in the first adsorption bed 51 and the first adsorption condenser 6161. Circulate in the first adsorption cycle formed by the connection of the first adsorption evaporator 71.

[0055] During the day, when the t...

Abstract

The invention relates to a refrigeration system with combination of adsorption and steam compression and a control method thereof. The refrigeration system comprises a compressor, an evaporative cooler, a throttling valve and an evaporator which are successively connected to form a steam compression refrigeration cycle and also comprises a first adsorption bed, a first adsorption condenser and a first adsorption evaporator which are successively connected to form a first adsorption cycle, wherein condensation heat released by the evaporative cooler is used for supplying heat to the first adsorption bed. The refrigeration system is capable of refrigerating through steam compression in the daytime, storing cold quantity by recycling the condensation heat generated in the steam compression refrigeration process and refrigerating by using the stored cold quantity at night, so that the energy is saved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration system combining adsorption and vapor compression and a control method thereof. Background technique [0002] In summer, the sunlight is strong and long during the daytime, the temperature is high, and the central air-conditioning load of public buildings is large; the temperature at night is relatively low, and the central air-conditioning load is low. During the operation of the central air conditioner, the simple consumption of electric energy consumes a lot of energy, and it needs to discharge a large amount of condensation heat when obtaining cooling capacity, which not only increases the thermal pollution of the city, but also has low air conditioning efficiency. The conventional energy-saving method is to use peak-shifting power consumption and water storage technology, but the power consumption of central air-conditioning is still very large, causing...
