Description

Technical field:

[0001] The invention belongs to the technical field of thermodynamics and heat pumps. Background technology:

[0002] For heat pump devices, reducing energy transmission links is a fundamental measure to improve performance index and reduce manufacturing costs. For high-quality fuels represented by natural gas, in order to improve the performance index of heat pump devices and reduce their manufacturing costs, direct combustion of fuels and direct use of gas as the working medium of heat pump systems have become the focus of heat pump technology research - among which, the process and property changes of gas in heat pump devices need to be carefully studied and comprehensively considered.

[0003] Abundant ambient air is an important option as a low-temperature heat resource. Using air directly as a working medium is the best way to eliminate irreversible losses in the low-temperature heat load acquisition link. For gas circulating working fluids, increasing the circulating working fluid flow rate in the heat absorption process and absorbing heat in the high-temperature section are effective means to increase the average heat absorption temperature. When the temperature variation range of the heated medium is large (large temperature span), it is appropriate to adopt variable temperature heating. In addition, it is also necessary to consider increasing the utilization depth of the low-temperature heat load.

[0004] Based on the basic principle of simply, actively, safely and efficiently utilizing high-temperature thermal energy to achieve cooling / heating, and for users with large temperature and heat spans, the present invention provides a direct-fired first-class heat-driven compression heat pump with reasonable process, simple structure, strong adaptability, direct or indirect provision of low-temperature heat load by air, high performance index, and the ability to achieve deep cooling and high-parameter heating.
