BAIJIAN - Third party testing organization
Heat recovery refers to the recovery of waste heat (cold) or heat (cold) inside and outside buildings、 and the utilization of the recovered heat (cold) as a heat source for heating (cold) or other heating equipment. The energy consumption in the construction industry includes energy consumption in the production of building materials、 construction、 and daily operation of buildings. The daily operational energy consumption of buildings、 also known as livelihood energy consumption、 also known as building energy consumption、 includes energy consumption for heating、 ventilation、 air conditioning、 hot water supply、 lighting、 elevators、 cooking、 etc. The energy consumption of urban buildings in China accounts for 22% to 24% of the national commodity energy consumption、 while developed countries account for about 1/3. Energy consumption also causes environmental pollution、 and the suspended particles、 SO2、 NOx、 and CO that affect the urban atmospheric environment are mainly the consequences of energy consumption; The emissions of greenhouse gases such as CO2、 which affect the global environment、 mainly come from energy consumption. The consumption of energy in cities also leads to the phenomenon of "urban heat islands". In order to achieve China's sustainable development strategy、 building energy efficiency is also imperative. The direction of architecture is "green building". One of the energy consumption characteristics of the air conditioning system is the simultaneous process of heat demand (cold、 wet) and heat removal (cold、 wet). For example、 low temperature and low humidity exhaust in summer can cool dry fresh air、 while high temperature and high humidity exhaust in winter can heat and humidify fresh air. By utilizing this feature、 the air conditioning system can be effectively heat recovered、 thereby reducing energy consumption. The heat that may be recovered in buildings includes exhaust heat、 interior heat、 condenser heat、 and drainage heat
