Heat and cold storage type gas-assisted solar absorption type ammonia water cooling system

Abstract

The invention discloses a heat and cold storage type gas-assisted solar absorption type ammonia water cooling system. The heat and cold storage type gas-assisted solar absorption type ammonia water cooling system mainly comprises a solar energy heat storage subsystem, an absorption type refrigeration subsystem, a cold storage subsystem and a chilled water subsystem; the absorption type refrigeration subsystem is internally provided with a primary generator and a secondary generator; the secondary generator is arranged below the primary generator; the solar energy heat storage subsystem provides heat for the primary generator; gas provides heat for the secondary generator; the cold storage subsystem comprises an expansion valve, a cold storage tank and an electromagnetic valve; the chilledwater subsystem comprises a fan coil; the fan coil is connected with a precooler through a chilled water pipeline which is provided with a chilled water pump and an electromagnetic valve and a chilledwater pipeline which is provided with an electromagnetic valve and a heat exchanger; an electromagnetic valve is arranged between the two chilled water pipelines; and the cold storage tank is connected with the heat exchanger through a solution pump. The solar energy absorption type ammonia water cooling system is combined with a heat and cold storage technology, so that the heat and cold storagetype gas-assisted solar absorption type ammonia water cooling system is energy-saving and environmentally friendly, and is high in energy gradient utilization rate and adjustability.
