The invention discloses a ventilation and heating system, comprising a daytime air intake pipe, an arc-shaped parabolic solar focusing plate is installed with the daytime air intake pipe, an air outlet fan is connected to the daytime air intake pipe, and a first heat exchange coil is wound around the daytime air intake pipe ; The first heat exchange coil, the heat exchange coil is communicated with an air compressor, and the air compressor is communicated with a second heat exchange coil; the second heat exchange coil is communicated with a third heat exchange coil; the third heat exchange coil The pipe is connected with the first heat exchange coil through the restrictor to form a loop; the third heat exchange coil is located in the water storage tower; the second heat exchange coil is located in the indoor hot air supply pipe; an air pump is installed on the hot air supply pipe; The daytime air intake pipe is communicated with the nighttime air intake pipe through the fourth heat exchange coil. The invention uses solar energy to store heat and heat the air, so that the outside air can be heated after the temperature is raised, the outside air heat energy is effectively utilized, and the application range of the existing air energy heat pump is improved. |
