An air source heat pump Introduction (A), what is the air source heat pump? Heat pump technology is a new energy technology attracting worldwide attention in recent years. It is a device that transfers heat from a low-temperature heat source to a high-temperature heat source by consuming a part of high-grade energy. The heat transferred to the high temperature heat source includes the high grade energy consumed and the amount of heat absorbed from the low temperature heat source. (B), air source heat pump hot water unit composition Air source heat pump water heater (unit) generally by the compressor, condenser, liquid storage tank, expansion valve, evaporator and other components. (C), air heat pump working principle Air heat pump at work, it consumes part of the energy itself, the energy stored in the air to be tapped, through the heat transfer medium circulation system to increase the temperature to make use of, and the entire heat pump device consumes only a small power output section. The use of heat pump technology can save a lot of high-grade energy. In operation, the evaporator draws heat from the surrounding environment to evaporate the heat transfer medium, the working fluid vapor through the compressor temperature and pressure rise, the high temperature steam condenses into liquid through the condenser, the heat released to the storage tank Water. Condensed heat transfer medium through the expansion valve back to the evaporator, and then be evaporated, so cycle back and forth. Second, air-source heat pump in the traditional advantages of fermentation 1, energy-saving: air-source heat pump than the current traditional steam heating with energy-saving advantages. 2, environmental protection: air source heat pump no toxic and harmful combustion emissions, no greenhouse gas emissions. Noise in line with environmental requirements. 3, Security: microcomputer control, complete hydropower separation, no leakage risk, no poisoning, explosion danger. 4, can use the original site, technology, equipment, small footprint, light weight, removable. 5, the boiler failure, repair costs, the use of air-source heat pump after the fermentation part of the boiler does not use, can greatly reduce boiler operating costs. 6, air source heat pump existing power supply system that can meet the requirements, do not need to transform the line. Air source heat pump does not require steam, circulating water, the original water, steam pipe does not need to be repaired. 7, in line with national advocacy of energy saving policy. Thus, air-source heat pump applications in the traditional fermentation has a good alternative value of energy saving, is a worthy development of new energy technologies. Third, air source heat pump in the application of traditional fermentation characteristics The application of air source heat pump in the traditional fermentation is the first of its kind in a comprehensive range. It is an exploration of the traditional fermentation energy. This technology has the advantages of low investment in equipment, low energy consumption, safety and environmental protection, and will open up a new revolution of traditional fermentation energy substitution.
