Description

technical field [0001] The invention relates to the field of air-conditioning systems, in particular to a small multi-mode solar-assisted household air-conditioning system. Background technique [0002] With the development of social science and technology and the improvement of people's living standards, people's requirements for residential comfort have also increased. The air conditioning system is the main equipment to improve the level of thermal comfort. The household split air conditioner has become the most widely used refrigeration system in the country because of its compactness and easy installation. With the installation of air conditioners increasing year by year, the huge cooling energy consumption in summer puts great pressure on the power grid. [0003] The solar-driven absorption air-conditioning system directly uses solar thermal energy as the driving energy, so it can effectively relieve the pressure on the power grid. However, due to the seasonality and...

AI Technical Summary

Problems solved by technology

[0004] Due to the same rated cooling capacity, compared with the compression refrigeration system, the volume of the absorption refrigeration machine is too large, and the miniaturization design will inevitably reduce the system performance

In addition, the widely used water-cooled lithium bromide absorption refrigeration system needs to be equipped with cooling towers, cooling water circulation and water supply pipes, etc., which makes the system structure complex and difficult to realize miniaturized residential applications; air-cooled lithium bromide absorption refrigeration system can meet the integrated structure design, but Easy to cause crystallization failure due to high cooling temperature

The absorption and compression coupling systems also have shortcomings in terms of volume and cooling performance, which seriously hinders the process of miniaturization and home use.

In addition, the existing absorption compression coupling system has a single operation mode and low solar energy utilization rate, which makes the system economical and difficult to promote
