Multi-energy complementation combined type heat pump air conditioner system for data machine room

Abstract

The invention discloses a multi-energy complementation combined type heat pump air conditioner system. The multifunctional complementation combined type heat pump air conditioner system is mainly composed of a high-temperature cold source 1, a heat pump unit 2, a water separating device 3, a water collecting device 4, a data machine room user 5, a cooling device 6, a common air conditioner user 7, a plate-type heat exchanger 8, a cold accumulation groove 9, a cold water primary pump 10, a circulating pump 11, a cooling water pump 12, a common air conditioner user side water pump 13 and a secondary pump 14, wherein a common water chilling unit, a heat pump unit, a steam type lithium bromide absorption unit, a hot water type lithium bromide absorption unit, an evaporative cooling air conditioner and the like can serve as the high-temperature cold source 1, a water-cooling air conditioner corresponding to an individual building /various data center machine tool plate-type heat exchangers corresponding to an area building can serve as the data machine room user 5, and a cooling tower, a hot source tower and the like can serve as the cooling device 6. In summer, the high-temperature cold source and the heat pump unit operate independently. In winter, the high-temperature cold source and the heat pump unit are combined to cool the data machine room, and the heat pump unit serves as a hot source of the common air conditioner user. In spring and autumn, free cooling can be achieved. By means of the cold accumulation groove, the principle of peak clipping and valley filling is adopted in the cooling capability, and energy saving is achieved to the maximum extent.

Description

technical field [0001] The invention relates to a multi-energy complementary composite heat pump air conditioning system. In summer, the high-temperature cold source and the heat pump unit operate independently; in winter, the high-temperature cold source and the heat pump unit operate jointly as the cold source of the data room, and the condensation side of the heat pump unit provides heat for conventional air conditioners at the same time; in transitional seasons, the invention can also realize Cooling towers provide "cooling for free". In addition, the present invention arranges a cold storage tank on the side of the data room to “cut peaks and fill valleys” of the cooling capacity in the compound heat pump air-conditioning system, and maximize the use of low-grade heat energy. Background technique [0002] With the continuous development of modern cities, the social power demand load has increased sharply, and the contradiction between the current situation of energy sh...
