Dynamic ice cold storage deicing system and method

Abstract

The invention relates to a dynamic ice cold storage deicing system. The dynamic ice cold storage deicing system comprises an ice storage tank, an ice crystal filter, a first valve, a circulating pumpand a supercooler which are arranged in sequence. Two supercooler inlet branches are arranged between the circulating pump and the supercooler. One supercooler inlet branch is provided with a second valve and a filter screen. The other supercooler inlet branch is provided with a third valve, a laval pipe and a fourth valve. An outlet pipe of the supercooler is connected with a ball collection tankthrough a deicing ball removing interceptor. An electric filter screen is arranged in the deicing ball interceptor. A fifth valve is arranged on an outlet pipe of a cooler. The ball collection tank is internally provided with deicing balls. A deicing ball outlet pipe of the ball collection tank is connected with the laval pipe through a sixth valve. The dynamic ice cold storage deicing system eliminates ice blockage in the manner that deicing balls circulate and flow in a pipe of the supercooler. The dynamic ice cold storage deicing system has the advantages that the system is simple in structure and reliable in operation and has no influence on cold storage energy consumption; and the deicing system and an ice storage system can operate simultaneously.

Description

technical field [0001] The invention relates to the technical field of dynamic ice storage ice making slurry, in particular to a deicing system and method for eliminating ice blockage in the process of dynamic ice storage ice making slurry. Background technique [0002] Ice storage technology is widely used in the field of building HVAC, which plays a role in peak-shaving and valley-filling of power loads. Compared with static ice storage, dynamic ice storage has the advantages of simple equipment, high storage energy efficiency, high cooling efficiency and stable load. It has become the main research direction in the field of cold storage, but there is a common problem that the outlet of the subcooler is blocked by ice and the system cannot operate. [0003] At present, for the problem of ice blockage in supercooled water ice slurry cold storage technology at home and abroad, electric heating or four valves are mainly used to switch the condenser and evaporator of the refri...
