Heat pump can be used for renewable energy recovery. Several units of renewable energy can be obtained with the consumption of one unit of electric or mechanical energy. Therefore

heat pump is an important energy saving and environmental protection technology. With the significant increase in energy demand and rapid development of electric power industry

the proportion of renewable energy in our country needs to be improved. Thus

heat pump technology plays a critical role. Heat pump technology has been listed as renewable energy in European Union. Then

the corresponding policy for our country is proposed. Based on the data of the power generating efficiency and transmission efficiency

it is concluded that heat pump is a technology for renewable energy recovery. Two calculation methods

including primary energy multiple α and renewable energy contribution rate β

are introduced

to provide a reference for the industry. The target of flue gas emission for power plant is much more stringent than the common coal-fired boiler

so utilizing heat pump to replace coal-fired boiler can improve atmosphere environment. It is suggested that the calculation method of renewable energy contribution rate for heat pump should be listed as a national standard. The heat pump manufacturing industry should be further developed

and heat pump technology should be widely applied.
