Abstract

The invention discloses a solar energy-natural gas combined driven energy saving air-conditioner, where the outdoor machine set comprises solar heat collector, solar heat storer and natural gas heater; a heat exchanger pipe coil in the solar heat collector is connected with the two ends of the other heat exchanger in the high pressure generator through the natural heater and circulating pump to drive indoor machine set to work. And it uses heat source as drive energy, integrating refrigeration, heating and living hot water supply; the condenser and absorber in the machine set adopt wind cooling, omitting the cooling water circulating system so as to be used at home and in medium- and small-sized buildings; and its performance coefficient can be up to above 1.5, reducing energy consumption and making full use of renewable energy source. In addition, it has characters of environmental protection, saving energy, and safety.

Description

1. Technical field

[0001] The invention relates to a refrigeration air conditioner, in particular to a high-efficiency energy-saving air conditioner driven by combined solar energy and natural gas. 2. Background technology

[0002] Since the reform and opening up, my country's comprehensive national strength and people's living standards have been greatly improved. As one of the basic industries of the national economy, the energy industry has achieved considerable development. However, the development of the energy industry still cannot meet the needs of the rapid development of the national economy and the rapid growth of people's daily energy consumption, and the national energy shortage situation still exists.

[0003] To solve the current energy shortage problem, it is necessary to develop renewable energy, such as solar energy, geothermal energy, biomass energy, wind energy, ocean energy and so on. Among various renewable energy sources, solar energy is the most impo...
