An air-type solar hot water fresh air system for passive houses

Abstract

The invention provides an air-type solar hot-water fresh air system oriented to passive houses. The air-type solar hot-water fresh air system comprises a solar thermal collector, a hot water tank, a water tank air inlet pipe, a water tank air outlet pipe, a first heat exchange coiler, a second heat exchange coiler, a first indoor air inlet pipe, a second indoor air inlet pipe and a total heat exchanger. The outlet end of the solar thermal collector is connected with the gas inlet end of the hot water tank through the water tank air inlet pipe; the gas outlet end of the hot water tank is connected with the inlet end of the solar thermal collector through the water tank air outlet pipe; the liquid outlet end of the hot water tank is connected with the inlet ends of the first heat exchange coiler and the second heat exchange coiler; the outlet ends of the first heat exchange coiler and the second heat exchange coiler are connected with the liquid inlet end of the hot water tank; the first heat exchange coiler is arranged in the first indoor air inlet pipe, and the second heat exchange coiler is arranged in the second indoor air inlet pipe; the first indoor air inlet pipe is connected with the second indoor air inlet pipe through the total heat exchanger. The air-type solar hot-water fresh air system has the advantage that the heat exchange coilers are used for pre-heating fresh air, so that the situation that air entering rooms is clean and pollution free is guaranteed to the greatest extent.

Description

technical field [0001] The invention relates to solar energy, in particular to an air-type solar hot water fresh air system for passive houses. Background technique [0002] In recent years, many countries and regions have paid more and more attention to the sustainability of development, and continuously increased research and development and investment in renewable energy. As one of the clean energy sources, solar energy has been paid attention to and widely used. For example, the photovoltaic power generation system has rapidly advanced in technology, and the scale of related manufacturing industries and development and utilization has gradually expanded, becoming an important field for the development of renewable energy. [0003] The basic methods of solar energy utilization can be divided into four categories: light-heat utilization, light-electricity use, light-chemical use, and light-biological use. Among the four types of solar energy utilization methods, the ligh...
