Problems solved by technology

[0008] (1) For the absorber, the higher-temperature dilute solution from the generator is directly returned to the absorber through throttling and depressurization, and a lot of cooling water is needed to cool the high-temperature dilute solution to the lower temperature required by the absorber. Low temperature, the heat of the high-temperature dilute solution is not fully utilized, and at the same time consumes a lot of valuable cooling water, and the cooling time will be long, which will lead to the consequences of prolonged running time of the system in non-air-conditioned conditions during operation ;
[0009] (2) For the generator, it takes a lot of heating water to heat it to the higher temperature in the generator from the cooler concentrated solution in the absorber, and it takes a lot of water to heat this part of the cold solution. Heat, which also prolongs run time in non-air-conditioned conditions

Abstract

The invention discloses back-heating type no pump ternary solution absorption refrigeration and air conditioning system. It is made up of three containers, twenty one electric globe valves, condenser, capillary tube, evaporator, and three throttle valves. The upper of the container is set sprinkler pipe. Its middle is set back-heating tube. And its lower is set heating tube. It has the advantages of no harmful gas, no noise, good performance, low cost, and long useful life. It can be used in huge-middle-small type refrigeration and air conditioning system. And it can be driven by hot water with 50-60 centigrade degree.

Description

technical field [0001] The invention relates to a heat recovery type pumpless ternary solution absorption refrigeration and air conditioning system, which belongs to the subject field of engineering thermophysics and energy utilization. Background technique [0002] Energy saving and environmental protection are the new goals pursued unremittingly by the development of modern science and technology worldwide and by scientists from all over the world. In refrigeration, air conditioning and heat pump systems, traditional refrigerants such as CFCs are being replaced by various mixed refrigerants and natural refrigerants due to their serious damage and impact on the ozone layer and people's living environment . Ammonia-water and lithium bromide-water are typical alternative refrigerants, but they have their own advantages and disadvantages. For example, the absorption refrigeration system using ammonia-water as the working medium has the advantage of using ammonia-water as the...
