The invention provides a thermochemical absorption and refrigeration device driven by condensation heat of an air conditioning unit. The thermochemical absorption and refrigeration device comprises an electricity compression type refrigeration air conditioning unit device and a thermochemical absorption and refrigeration air conditioning device connected with the electricity compression type refrigeration air conditioning unit device, wherein the electricity compression type refrigeration air conditioning unit device comprises a compressor, a heat recoverer, a condenser, a throttling valve and an evaporator; the thermochemical absorption and refrigeration air conditioning device comprises a heat storage water tank, a main reactor, an auxiliary reactor, a reactor heat exchange coiler, a voltage transformation desorption regulating valve, a desorption valve, an absorption valve, a main absorbent, an auxiliary absorbent, an ammonia condenser, an ammonia evaporator, an ammonia refrigerating fluid storage unit, a refrigerating fluid, an ammonia throttling valve and a cooling tower. By the thermochemical absorption and refrigeration device driven by condensation heat of the air conditioning unit, the recovery and utilization range of the condensation heat is expanded; moreover, under the condition of keeping the power consumption of the compression type refrigeration air conditioning unit constant, the cooling quantity is increased by recycling the condensation heat to drive thermochemical absorption and refrigeration, and the energy-saving function of the refrigeration air conditioning unit is realized.

Description

technical field [0001] The invention relates to a device in the technical field of air-conditioning and refrigeration, in particular to a thermochemical adsorption refrigeration device driven by condensation heat of an air-conditioning unit. Background technique [0002] With the continuous improvement of people's living standards, refrigeration and air-conditioning units are more and more widely used. In summer, air-conditioning units have to discharge a large amount of condensation heat when they are operating in refrigeration conditions. These large amounts of condensation heat are usually not effectively recycled. Being directly discharged into the atmosphere, on the one hand, it causes a large waste of energy, on the other hand, it increases the ambient temperature around the building, causing serious environmental thermal pollution, especially for star hotels, tourist hotels, hospitals, schools, For restaurants, shopping malls and large public places, the situation is ...

Problems solved by technology

Judging from the current technology, due to the high temperature of the driving heat source required by the traditional lithium bromide-water absorption refrigeration unit, the temperature of the hot water recovered from the condensation heat is low and the refrigeration cannot be realized. However, the thermochemical adsorption refrigeration technology used in this patent and Pressure swing desorption technology provides an effective method for recovering condensation heat to achieve refrigeration
