Multi-source complementary collecting-distributing heat source tower heat pump system

Abstract

The invention discloses a multi-source complementary collecting-distributing heat source tower heat pump system. The system comprises a refrigerant loop, a heat source tower loop, a soil energy supplyloop, a solution regeneration loop and a photo-thermal auxiliary regeneration loop. Compared with the prior art, a plurality of indoor heat exchangers are arranged in the building outer area, and aredirectly connected with a heat source tower heat pump main machine through the refrigerant loop, so that that a cold and hot source system is guaranteed to be efficient, meanwhile, the independent and flexible control of rooms one by one is achieved, and the efficiency under a part of loads is improved; a plurality of indoor heat exchangers are arranged in the building inner area, so that the heat of the building inner area is fully utilized, the autonomous regeneration of a solution is realized, the stable operation of the system is ensured, and the system efficiency is improved; and a heatsource tower heat pump single-supply mode, a soil loop direct supply mode and a heat source tower heat pump and a soil loop combined supply mode are provided, and inner area waste heat self-regeneration and photo-thermal auxiliary regeneration are combined, so that the system can be guaranteed to stably and efficiently run under the conditions of extreme working conditions, partial loads and the like.

Description

technical field [0001] The present invention relates to the field of design and manufacture of refrigeration and air-conditioning systems, in particular to a multi-source complementary collecting and distributing heat source that utilizes soil loops to realize peak regulation, heat in the inner area of ​​a building and assisted by light and heat to realize solution self-regeneration, and combines centralized cold and heat sources with decentralized terminals. Tower heat pump system. Background technique [0002] At present, the heating and air-conditioning systems commonly used in buildings are chillers plus boilers, air source heat pumps and water ground source heat pumps. When the chiller plus boiler is running in winter, the chiller will be idle, and the equipment utilization rate is low. The primary energy utilization rate of the boiler is low, and it will pollute the environment during use. The efficiency of air source heat pumps in summer is much lower than that of w...
