实际上,在寒冷季节,所有建筑的排气系统所排出的气温远高于室外气温,可用它作为进气加温的热源。为饲养牲畜和家禽,在农业建筑的采暖通风系统中合理地利用排气中的热量,具有较大的经济意义。计算表明,在许多气候区内,禽畜所产生的余热和余湿完全可作为热源用来加热进入的冷空气。这样在不需热能设备的情况下,即可保证饲养室内的空气具有标准的卫生参数。从排气中回收热量可在不同结构系统的热交换器中进行。当排气系统离进气系统较
In fact, in the cold season, the temperature of the exhaust system of all buildings is much higher than the outdoor air temperature, and it can be used as a heat source for heating the intake air. In order to raise livestock and poultry, it is of great economic importance to rationally use the heat from the exhaust in the heating and ventilation systems of agricultural buildings. Calculations show that in many climatic zones, the excess heat and moisture generated by livestock can be used as a heat source to heat the incoming cold air. This ensures that the air in the breeding room has standard hygiene parameters without the need for heat energy equipment. The recovery of heat from the exhaust gas can be performed in heat exchangers of different structural systems. When the exhaust system is away from the intake system
