Description
Technical field
A kind of hot gas defrosting device is the utility model is related to, belongs to Refrigeration Engineering field.
Background technology
In general supermarket's project, the defrost of showcase and freezer is by the way of electric heating tube defrost.Thisization
Following several aspect deficiencies be present in white mode：
By the way of electric heating tube, directly heat, electric current is also larger when defrost works, corresponding distribution and electrical equipment member
Part is all bigger, and most importantly power consumption is bigger, and month after month, this is the no small expenditure of pen for supermarket operates throughout the year.
Electric heating tube is generated heat by heating tube, is thermally conducted to complete the process of defrost, heat transfer effect in evaporator fin
Rate is not 100%, and has more heat to be risen to hot-air inside cupboard, so as to cause larger refrigerator internal temperature
Rise, the risk that certain marketing quality deteriorates be present.
For freezer, freezer pendulum goods in Mini Supermarkets is not very strict, a certain degree of carton be present and has stacked
Come, touch the possibility of air-cooler bottom drip tray, now heating tube heats, and easily causes fire.
Utility model content
The purpose of this utility model is to provide a kind of hot gas defrosting device, cancellation electric heating tube Defrost mode, using system
Cold compressor, which is vented, enters directly into evaporator coil progress defrost, the synergy between multiple magnetic valves, using controller
It is uniformly controlled, completes smooth toggling between refrigeration and defrost.
The utility model solves above-mentioned technical problem by following technological means：
A kind of hot gas defrosting device of the present utility model, it includes feed pipe, muffler and heating pipe, and feed pipe passes through exhibition
Show that the evaporator coil in cabinet connects with muffler and heating pipe, the connectivity part of feed pipe and showcase is provided with feed flow electromagnetism
Valve, is parallel with bypass non-return valve on liquid supply electromagnetic valve, and the connectivity part of muffler and showcase is provided with return-air magnetic valve, heating pipe
The connectivity part of showcase is provided with defrost magnetic valve, muffler connects with heating pipe.
Main line magnetic valve is provided with the feed pipe.
The quantity of showcase is at least one, is connected in parallel between showcase.
The feed pipe and muffler connect with compressor, and the hot gas in heating pipe is the exhaust of compressor.
Manual ball valve is in series with the liquid supply electromagnetic valve, return-air magnetic valve and defrost magnetic valve.
Normal process of refrigerastion：Main line magnetic valve, liquid supply electromagnetic valve and return-air magnetic valve are opened, defrost closed electromagnetic valve.
The equal normal open of all manual ball valves.Refrigerant is after compressor comes, and by main line magnetic valve, each displaying is given in then liquid separation
Cabinet, then by evaporator of the liquid supply electromagnetic valve feed flow to showcase, after the expansion valve throttling carried by refrigerator sweat cooling,
Overheated gas after evaporation returns to compressor air suction chamber by return-air magnetic valve, completes to continue next circulation.
Defrost process：The equal normal open of all manual ball valves.The separately defrost successively of each showcase, before this first showcase
Defrost, process are：Main line magnetic valve is closed, the liquid supply electromagnetic valve late release of first showcase, the confession of the second showcase
Liquid electromagnetic valve is kept it turned on, the return-air magnetic valve late release of the first showcase, and then the defrost magnetic valve of the first showcase is opened
Open, now hot gas enters muffler by heating pipe, then into inside evaporator, is changed into liquid refrigeration after heat absorption condensation
Agent, then the bypass non-return valve of the first showcase enter in the second showcase, complete the second showcase process of refrigerastion.Second
During showcase defrost, the defrost process of similar first showcase, then carry out successively.
The beneficial effects of the utility model：A kind of hot gas defrosting device of the present utility model, cancel electric heating tube, distribution and
Switch reduces, and defrost uses the exhaust of compressor, and power consumption is saved.
Compressor high-temperature exhaust air is entered directly into inside evaporator coil, and from inside to outside, defrost effect greatly enhances, outdoor
The standard defrost time greatly shortens under state.
Because hot gas is passed directly in evaporator coil, defrost is smaller on the temperature influence in cabinet, can preferably protect
Hold the quality of food.
