Domestic solar airlift pump absorption type air conditioning system

Abstract

The invention discloses a domestic solar airlift pump absorption type air conditioning system, which comprises a hot water system, an absorption type refrigerating unit, an air-conditioner indoor unit and a water and heat supply pipeline. The hot water system comprises a solar thermal collector and a first water pump, and the absorption type refrigerating unit comprises a generator, an airlift pump, a separator, a condenser, an evaporator and an absorber. The separator is highest in the absorption type refrigerating unit, the condenser, the evaporator, the absorber and the generator are sequentially lowered in position, the generator is connected with the separator via the airlift pump, and fluid in the parts is driven to flow by the aid of altitude difference and density difference. The absorption type refrigerating unit of the air conditioning system uses no mechanical pump, so that noise can be effectively reduced, power consumption is reduced, and cost is saved. Further, the condenser and the absorber both use a forced air cooling way instead of a cooling water system, application range can be widened, the system can be simplified, and miniaturization and domestication are facilitated.

Description

technical field [0001] The invention belongs to the technical fields of building environment and equipment engineering and refrigeration engineering, and relates to an air conditioning system, in particular to a household solar air bubble pump absorption air conditioning system. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, heating and air conditioning in public buildings and residences has become a common demand, and the resulting shortage of energy supply has become a common problem faced by countries all over the world today. In my country, the number of household air conditioners has exceeded 100 million, and at the same time, it is growing at a rate of 20% every year. Residential central air conditioners and commercial central air conditioners have become more popular. It has become an important factor for the rapid growth of grid load. At the same time, the most widely used refrigerators i...

Problems solved by technology

This device has the characteristics of high efficiency, freezing resistance, fast start-up, good heat preservation, etc., but the device has a complex structure, high cost, large water consumption, and is difficult to miniaturize and household, and it is difficult to be used in arid and water-deficient areas in Northwest my country ; Patent No. 03129268.2, titled "Composite Solar Refrigeration Device", uses solar energy and electric energy to jointly drive a kind of absorption-compression composite refrigerator. In the cooling mode, when the solar energy is insufficient, the device is driven by electric energy and operates in a single-stage compression refrigeration mode. Therefore, the control system of the device is complicated, consumes electric energy and a large amount of cooling water, and is also difficult to miniaturize and household
