Technical field:

the invention belongs to the technical field of thermodynamics and heat pumps.

The background technology is as follows:

the fuel combustion releases high-temperature heat energy, and can be used for refrigeration or obtaining low-temperature load to realize high-efficiency heat supply.

Advanced heat pump technology is required to meet different conditions and requirements. In addition, because of being limited by one or more factors such as the working principle, the property of the working medium, the material property, the manufacturing level of equipment and other parts, and the like, a large temperature difference is unlikely to be lost in the gas forming process, which provides opportunities for the efficient utilization of low-grade fuel/heat source media.

The first type of heat driven compression heat pump technology taking the first type of heating cycle as the working principle is a basic means for refrigerating and efficiently supplying heat by utilizing high-temperature heat energy; the device has the advantages that the device can meet the requirements of variable temperature heat supply and high temperature heat supply and can fully utilize the high temperature load of fuel gas; however, when the temperature of the low-temperature heat resource is low (for example, ambient air is used as the low-temperature heat resource) or is a constant-temperature heat resource, the temperature change range of the endothermic process for acquiring the low-temperature heat load is required to be as small as possible; in order to minimize irreversible loss of heat transfer temperature difference between high temperature fuel gas and circulating working medium, high boost ratio is needed in the compression process of the system.
