A cold and heat source fresh air component for near-zero energy buildings

Abstract

The invention discloses a cold and heat source fresh air device for buildings with near zero energy consumption, which includes a heat source fresh air assembly, a cold source fresh air assembly, a hot air exhaust pipe, a cold air exhaust pipe, a main support frame and a cold and heat exchange assembly. A heat source fresh air device is installed directly below the cold source fresh air device. The hot air exhaust pipe and the cold air exhaust pipe are sealed and penetrated on the outer building wall. The pipe discharges the fresh air heat source into the building, so that the fresh air heat source enters the building and forms an internal warm current from bottom to top; the cold air exhaust pipe is connected with the cold source fresh air component, and the building is discharged into the fresh air cold source through the cold air exhaust pipe , the heat source fresh air component and the cold source fresh air component are connected with a cold and heat exchange component, and the cold and heat exchange component heats and cools the heat source fresh air component and the cold source fresh air component respectively, so that the heat source fresh air component and the cold source fresh air component reach Cold and heat source fresh air temperature threshold.

Description

A cold and heat source fresh air component for near-zero energy buildings technical field The present invention relates to the technical field of building air purification and conditioning equipment, in particular to a kind of cooling system for near-zero energy consumption buildings. Heat source fresh air components. Background technique [0002] Near-zero energy buildings are also called "passive houses", a concept developed in Germany in the 1980s for low energy consumption. Based on the architectural concept, they believed that a passive house should be possible without an active heating and air-conditioning system. Buildings that maintain a comfortable indoor thermal environment. The energy consumption per unit square meter of heating and cooling required by it is higher than that of traditional buildings. up to 90%. Passive house buildings have excellent airtightness and thermal insulation measures, and a fresh air system must be used to ventilate the room. An...

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 the gas after living in the building. coal-fired appliances for cooling or heating, so it is necessary to propose a cold and heat source fresh air component for near-zero energy buildings to solve the above problems
