Abstract

The invention discloses a high temperature heat pump system and a circulation method thereof. The high temperature heat pump system comprises a second class absorption heat pump subsystem and a steam compression type heat pump subsystem; and the steam compression type heat pump subsystem uses an absorption condensation heat exchanger of the second class absorption heat pump subsystem as a compression type evaporator of the steam compression type heat pump subsystem and uses a generation heat exchanger of the second class absorption heat pump subsystem as a compression type condenser. By means of the high temperature heat pump system and the circulation method, the problems that a steam compression type heat pump cannot make high temperature heat easily, and most process waste heat of a second class absorption heat pump has to be used for driving rather than making process steam are solved.

Description

technical field [0001] The invention relates to the technical field of heat pumps of thermal energy engineering, in particular to a high temperature heat pump system and a circulation method thereof. Background technique [0002] Due to the control of ozone-depleting substances by the Montreal Protocol, it is difficult for a vapor-compression heat pump driven by electricity to find a high-boiling refrigerant with excellent performance and environmental friendliness to produce high-temperature heat above 100 °C. In this way, in the industrial field, the vapor compression heat pump cannot be effectively applied to the heat-using process that usually requires process steam with a saturation temperature above 120°C. Therefore, in the field of industrial energy saving, it is very important to develop an electrically driven high temperature heat pump technology that can use low-grade process waste heat to produce process steam with a saturation temperature above 120°C. For a high...
