Cold and heat source fresh air device for near-zero energy consumption building

Abstract

The invention discloses a cold and heat source fresh air device for a near-zero energy consumption building. The cold and heat source fresh air device comprises a heat source fresh air assembly, a cold source fresh air assembly, a hot air exhaust pipe, a cold air exhaust pipe, a main supporting frame and a cold and heat exchange assembly, the heat source fresh air assembly is arranged below the cold source fresh air assembly, the hot air exhaust pipe and the cold air exhaust pipe are both arranged on an outer building wall in sealed and penetrating modes, the hot air exhaust pipe communicateswith the heat source fresh air assembly, a fresh air heat source is exhausted into a building through the hot air exhaust pipe, and internal warm flow is formed from bottom to top after the fresh airheat source enters the building; and the cold air exhaust pipe communicates with the cold source fresh air assembly, a fresh air cold source is exhausted into a building through the cold air exhaust pipe, the cold and heat exchange assembly communicates between the heat source fresh air assembly and the cold source fresh air assembly, the cold and heat exchange assembly heats and refrigerates theheat source fresh air assembly and the cold source fresh air assembly separately, and the heat source fresh air assembly and the cold source fresh air assembly reach a cold and heat source fresh air temperature threshold value.

Description

Technical field[0001]The present invention relates to the technical field of building air purification adjustment equipment, in particular a hot and cold source new wind device for nearly zero energy consumption.Background technique[0002]Near zero-energy building is also known as "passive room", this concept is based on the low-energy architectural concept in Germany in the 1980s, they believe that the passive room should be the heating and air conditioning system that does not have to take the initiative. Construction of a comfortable indoor thermal environment can be maintained. The unit of heating and cooling energy consumption it needs is as high as the traditional building than 90% compared to traditional buildings. The passive room has excellent sexy and insulation and insulation, and the new wind system must be used to ventilate the indoor ventilation. The new wind device in the prior art does not adapt to the passive room well, and the energy saving effect is not good, espec...

AI Technical Summary

Problems solved by technology

However, the fresh air device in the prior art cannot be well adapted to the passive house, and the energy saving effect is not good, and especially for the adjustment of the cold and hot temperature control, it cannot reach an excellent state, so that the residents still need to pass through the combustion air after living in the building. Therefore, it is necessary to propose a cold and heat source fresh air device for near-zero energy buildings to solve the above problems
