Abstract

The invention discloses a small multifunctional solar battery air conditioner, comprising outdoor unit, indoor unit, solar heat collector and energy storage tank, where outdoor heat exchanger is connected with the solar heat collector and adopts air cooling. And it integrates refrigeration (cold storage) and heating (heat storage) as well as living hot water supply, having characters of compact structure and unit miniaturization; its cold storage density is higher than that of water cold storage system; on the condition that outdoor temperature is below -15deg.C, it can still normally supply heat indoors, and the heat temperature is uniform. And its performance coefficient can be up to above 3.0, reducing energy source consumption, fully using renewable energy sources and balancing power loads. In addition, it has characters of environmental protection, saving energy, safety, etc.

Description

1. Technical field [0001] The invention relates to a refrigeration air conditioner, in particular to a small multifunctional solar energy storage air conditioner 2. Background technology [0002] As a clean energy source, solar energy is both a primary energy source and a renewable energy source, and has incomparable advantages over fossil energy sources. According to calculations, the sun can release 391×10 21 kW of energy, and although the energy radiated to the surface of the earth is only 1 / 2.2 billion, it is equivalent to 80,000 times the current total power generation in the world. Therefore, solar energy resources are very rich, and it is the most eye-catching, most developed and most widely used clean energy among renewable energy sources. At present, the utilization of solar energy is mainly the utilization of light and heat, such as solar water heaters, and the utilization of photovoltaics, such as solar cells. Considering the cost of use and wide application, th...
