As air pollution is serious, environmental protection is becoming stricter, CO2 emissions are more stringent, the value of energy saving and energy recycling is becoming more and more obvious. Energy-intense industries system, such as thermal power plant, metallurgy, printing and dyeing, food industry, there are a large number of 40 ℃ to 80 ℃ heat with waste water, waste gas discharge, the heat loss, lower thermal efficiency. The high temperature heat pump can recover the waste heat, raise the temperature and then apply it to industrial production, civil heating, etc., reducing the energy cost and improving the energy efficiency.
