Description

Kitchen linkage fresh air machine air supply system suitable for ultralow energy consumption building Technical Field The invention relates to the field of building ventilation, in particular to a kitchen linkage fresh air machine air supplementing system suitable for an ultralow-energy-consumption building. Background In order to achieve the efficient ventilation effect of the ultralow-energy-consumption building, no extra building energy consumption is generated, and the ultralow-energy-consumption building generally adopts a heat recovery fresh air machine to recycle indoor exhaust waste heat so as to precool or enable the waste heat to enter indoor fresh air outdoors and ensure the quality of the indoor fresh air. For a household residential building, the unit is often arranged in a suspended ceiling space of a kitchen or a bathroom, and is far away from a frequent activity area of personnel, so that on one hand, the influence of noise generated when the unit operates on the comfort level of personnel in areas such as a living room and a bedroom can be avoided, and on the other hand, the fresh air unit is arranged in the suspended ceiling space of the kitchen or the bathroom, and the living room or the bedroom does not need to be provided with a suspended ceiling, so that the influence on the height of the living room or the bedroom area can be avoided. The direct introduction of fresh air through the kitchen outer wall opening is a common mode of kitchen air supply, a kitchen air supply system, the bulletin number is CN 212108908U, and an ultra-low energy consumption passive house kitchen air supply system air pipe penetrates the outer wall structure, the bulletin number is CN 213897570U. Fresh air is introduced into the outer wall hole to supplement air, and under the action of negative pressure, the fresh air is wrapped with the fume and is discharged into the fume exhaust well through the fume exhaust fan, so that ventilation in a kitchen is ensured. However, for the ultra-low energy consumption building, outdoor fresh air is directly introduced into a kitchen without treatment, so that the average temperature of the kitchen is lower than or higher than a design value, and the maintenance of an equilibrium temperature field in an airtight area of the ultra-low energy consumption building is not facilitated, and the winter and summer sections are particularly obvious.
