Double-power single-pass drive heat pump with double-clutch gearbox switched

Abstract

The invention discloses a double-power single-pass drive heat pump with a double-clutch gearbox switched. The double-power single-pass drive heat pump comprises a drive module, a compression module, apower control switching module, a heat exchanger module and an operation mode control module, wherein the drive module comprises a gas engine and a motor; the power control switching module is configured to receive an instruction of the operation mode control module, select gas engine input and drive the compression module to conduct heating or select motor input and drive the compression moduleto conduct heating/refrigerating; and the heat exchanger module is configured to output cold energy/heat energy. The compression module is configured to complete refrigerating/heating circulation through a refrigerant. According to the double-power single-pass drive heat pump with the double-clutch gearbox switched, the utilization rate of primary energy can be increased, the electric power or gasoperation mode can be switched according to the load requirement, the operation environment, the electric power and gas price and the electric power and gas supply situation, stable system operationis ensured, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of heat pumps, in particular to a dual-power single-pass drive heat pump switched by a dual-clutch gearbox. Background technique [0002] The heat pump system is a device that drives the compressor to do work through external power input, and transfers the low-level heat source to the high-level heat source. It can effectively utilize the low-grade heat energy that is difficult to use to achieve the purpose of energy saving. The heat pump device is mainly equipped with four items: evaporator, condenser, expansion valve and compressor. Conventional heat pumps use an electric drive motor to power the heat pump system, and a gas-in-gas drive heat pump to power the system. Both have their own advantages and disadvantages: the electric drive heat pump is powered by electric energy to drive the direct drive compressor to do work. Because it uses electric energy, it has the advantages of stable operation, low noise, small s...

Problems solved by technology

[0003] The heat generated by the engine itself in the gas heat pump can be used as additional heat supply under the heating condition, but under the cooling condition, the heat utilization is limited, and the heat may even need to be discharged directly

Electric-driven heat pumps do not have similar problems in cooling conditions, but relatively, electric-driven heat pumps have lower system output in heating conditions, and because defrosting conditions affect their heating continuity

[0004] From the point of view of fuel prices, the supply and price of gas and electricity will change at different times, such as tight supply of gas in winter and higher prices, tight supply of electricity in summer, and changes in prices such as peaks and valleys, so single-energy heat pumps It is difficult for the system to make full use of price changes of different energy sources to achieve maximum economic benefits

At the same time, due to the unbalanced energy supply, there may be power outages in summer, and unstable gas supply often occurs in winter. When encountering energy instability / stop periods, the single-system energy system will completely fail to operate
