Abstract

The invention discloses an alternating-current and gas engine parallel dual-drive heat pump device, which comprises a heat pump unit, an alternating-current motor, a gas engine and a transmission unit. An output end of the alternating-current motor is connected with an input end of the transmission unit by an alternating-current motor clutch, an output end of the gas engine is also connected with the input end of the transmission unit by a gas engine clutch, and an input end of the heat pump unit is connected with an output end of the transmission unit by a heat pump clutch. An urban alternating-current pipe network and the gas engine are technically combined, the urban alternating-current pipe network drives the motor, accordingly, load change can be balanced, simultaneously, a unit can be driven to run for a long time during gas shortage due to the fact that an electric driving portion is directly connected into an urban alternating-current grid, six different operating modes can be realized, utilization rate of primary energy can be improved, and carbon emission is reduced relatively.

Description

technical field [0001] The invention relates to a heat pump device in the field of hybrid power, in particular to a parallel dual-drive heat pump device with alternating current and gas engine. Background technique [0002] Although the annual production capacity of household air conditioners in my country ranks first in the world, the cost has dropped rapidly and its technical level has also been greatly improved. However, my country is a developing country with a large population, rapid economic development, and a relatively weak power base. The single development of electric air conditioning has brought a series of consequences: [0003] First, to further increase the peak power load in summer, so that the power supply in summer is tense. Due to the characteristics of intermittent operation and short operation time of residential air conditioners in our country, the characteristics of electric load are further deteriorated. [0004] Second, household air conditi...
