Description
Technical field
The invention belongs to defrosting equipment technical field, be related to it is a kind of for fishery cold-stroage boat except defrosting system.
Background technique
Large-scale fishery cold-stroage boat or large-scale catching factory ship are used exclusively for the function of fishery transport or fishing
Energy ship, since the refrigerated fish hold length and width size of such type ship is very big, the catches accumulation in refrigerated fish hold is higher, and one
As using air-cooled heat exchanger cool down, thus to catches carry out fresh-keeping and cold storage.Because the storage temperature of catches is lower no matter
The evaporator that cooling or non-freezing solution cools down indirectly in such a way that refrigerant directly evaporates, the humid air in cabin can all exchange heat
Certain frost layer is formed on device surface.The frost layer that heat exchanger surface is formed reaches certain thickness, will serious reduction heat transfer effect
Rate cannot not only ensure that the environment temperature in fish hold, the quality of catches are also unable to get guarantee.
In the refrigeration system for using air-cooled heat exchanger at present, widest defrosting mode is：Hot water defrosting, electric heating melt
Frost, hot gas defrosting, hot water defrosting is the frost layer heat water-spraying outside evaporator, carries out heat exchange defrosting；Electric heater defrosting is
On an evaporator heating wire winding, electrified regulation carries out defrosting；Hot gas defrosting is then the high temperature and pressure excluded using compressor
Gas is passed directly in evaporator, so that the frost layer outside evaporator is absorbed heat and is melted.
Above-mentioned defrosting mode has following insufficient：Electric heater defrosting need to expend a large amount of electricity, and economy is not good enough；And hot gas melts
Though white mode efficiency is higher, initial stage investment is high, and because misoperation can cause the safety accidents such as liquid hammer.
In addition, the water droplet after defrosting is easily hung on heat exchanger surface in traditional hot water defrosting mode, work as refrigeration system
When being again started up operation, the water meeting rapid condensation Cheng Bing of heat exchanger surface influences heat transfer efficiency, causes defrosting number to increase, cabin
Interior temperature fluctuation is frequent, and thus not only fishery harvesting amount of substance not can guarantee, but also it is big to consume energy, and economy is low.
