First-class thermal driving compression heat pump

Abstract

The invention provides a first-class thermal driving compression heat pump and belongs to the technical field of power, refrigeration and heat pumps. An air channel is arranged outside to communicate with a compressor. The compressor is further provided with a compressed air channel which communicates with a combustion chamber. The combustion chamber is further provided with a fuel channel which communicates with the outside. The combustion chamber is further provided with a fuel gas channel which communicates with a gas turbine. The gas turbine is further provided with a fuel gas channel which communicates with the outside through a high-temperature heat exchanger. A second compressor is provided with a circulation medium channel which communicates with an expansion machine through a high-temperature heat exchanger. The expansion machine is provided with a circulation medium channel which communicates with a second expansion machine through a heat supplier. The second expansion machine is further provided with a circulation medium channel which communicates with the second compressor through a low-temperature heat exchanger. The heat supplier is further provided with a heated medium channel which communicates with the outside. The low-temperature heat exchanger is further provided with a low-temperature thermal medium channel which communicates with the outside. The gas turbine, the expansion machine and the second expansion machine are connected with the compressor and the second compressor and used for transferring power, and thus the first-class thermal driving compression heat pump is formed.

Description

Technical field: [0001] The invention belongs to the technical field of power, refrigeration and heat pump. Background technique: [0002] Cold demand, heat demand and power demand are common in human life and production; in reality, people often need to use high-temperature heat energy to achieve cooling, heating or conversion into power, and also need to use power for cooling or use power combined Low temperature thermal energy for heating. In the process of achieving the above goals, there will be many considerations or constraints, including the type, grade and quantity of energy, the type, grade and quantity of user needs, ambient temperature, type of working medium, equipment flow, structure and Manufacturing costs and more.

Problems solved by technology

[0003] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology utilizes high temperature heat load to drive heat supply or cooling; big limit

Compression heat pump technology that utilizes the grade difference between mechanical energy and thermal energy has certain flexibility, but in many cases it is difficult to achieve efficient utilization of thermal energy

At the same time, the two technologies also have a common deficiency - they cannot convert thermal energy into mechanical energy while heating or cooling
