How do I know if my chest freezer is working

After a period of time the use of the chest type freezer may be a variety of small problems exist, some problems are caused by improper use of the user, and some are the quality of the chest freezer itself. So how do you know if the chest home freezer is working properly?

• How to judge whether the chest freezer operation is normal?

• How to check whether the chest freezer is aging?

• How to distinguish the quality of chest freezer good with bad?

How to judge whether the chest freezer operation is normal?

1.Evaporator surface with uniform frost layer; chest freezer has more frequent stop phenomenon; The downtime should be less than the downtime for insulation.

2.No noise when running, the compressor running smoothly, no violent vibration, a clear, continuous consistent sound of inlet and exhaust valve plate, and slight friction sound ', there should be no metal impact sound or friction noise.

3.Hand touch: the temperature of the compressor housing is stable, the hand touch does not feel hot; When the surface of the condenser is touched by hand down from the air inlet, the temperature should gradually decrease and the temperature difference should be obvious.

4.Test: use a thermometer to test the temperature in the chest freezer, should gradually drop, and can be in 2 hours or so, reach the specified chest type freezer, freezer temperature range.

How to check whether the chest freezer is aging?

Check whether the chest freezer plug is normal. When the chest home freezer used for a few years, suddenly one day found that the chest freezer did not cool, the first thing we thought of is definitely not the chest type freezer power plug did not plug, but think how much money to repair. But when the maintenance personnel came only to find that the chest freezer power is not plugged in. So when the discovery freezer does not refrigerate when need to check above all power supply is loosened.

Compressor operation is normal. If the power supply is normal and the lamp in the chest freezer is also on, then please don't worry, we need to find the compressor in the chest home freezer now, to hear if the compressor is working normally. It is important to note here that our bodies must not be in direct contact with the compressor.

Whether the buffer tube of the chest freezer is broken or not. If the compressor of the chest freezer is running normally, then open the back cover of the chest freezer and see if the screw fixing the buffer tube is loose, because when the buffer tube breaks, the screw fixing it will become loose. We just need to replace a new buffer tube and tighten the screw.

Whether the refrigeration system is leaking. If all else fails, you just plug in the freezer and run it for a few minutes, then unplug it, lie on the side of the freezer and listen for the sound of liquid flowing through the copper pipes. If you don't hear it, there's a good chance the refrigerant is leaking. If there is a leakage of refrigerant, then you need to find professional maintenance personnel to repair and add refrigerant.

Whether the door seal of chest freezer is aging. If everything is normal but freezer still does not refrigerate, can check below freezer door seal appears ageing, be out of shape. We can ask the professional repairman to change the seal.

How to distinguish the quality of chest freezer good with bad?

The core of the chest freezer is its compressor, a chest home freezer needs refrigeration will rely on the compressor to run. So the importance of the compressor can be imagined, so the compressor good, the quality of the chest type freezer is completely different. We can drop a few drops of water on the evaporator and see if it turns into ice in a few seconds, which means the compressor is good. Chest freezer adopts famous brand efficient compressor, which can cool quickly, make less noise, and is safe and stable.

The foamed layer of chest freezer, it is freezer keep warm layer, only it is good, ability keeps the freezer inside freezer freezer, freezer ability refrigerates, otherwise refrigerate, cool air ran away, impossible refrigerate good food. So it's important whether it's good or bad. The word that discriminates good foaming layer is about to try with the hand, good foaming knead rises very real, weight is very heavy also, and keep fresh effect, energy-saving effect is better.

The evaporator of chest freezer is a very important part, its stand or fall decides freezer refrigeration speed and preservation quality. Freezers are designed with full air cooling, super large evaporation area copper tube, fast refrigeration, preservation display effect. Evaporator design: to design the evaporator, in addition to the given load, but also given the evaporation temperature, superheat and into the expansion valve before the liquid temperature. (2) cooling capacity: cooling capacity directly determines the effective evaporator evaporation area is the number of fins, size and length of the pipeline.

Refrigeration system: observe whether there are cracks, damages, frost and dew in the pipelines of the refrigeration system; Cooling pipe, pipe and shell have to encounter friction between, especially the refrigerant piping welding, joint joint leaks, where the leak will have oil (refrigeration system have a certain amount of refrigerant oil), also can use a clean soft cloth, soft paper to wipe the pipeline welds and joints joint, observe whether the oil, to determine whether the leak.

Electrical system: observe whether the fuse of the electrical system is broken, whether the insulation of the electrical wire is intact, whether the circuit board is broken, whether the connection is loose, etc. In particular, whether the electrical connection is in good contact, connection screws and connectors are easy to loose, resulting in poor contact.

Ventilation system: observe whether the air filter, heat exchanger coils and fins accumulate too much dust; Whether the air inlet and outlet are smooth; Whether the fan and fan blade operate normally; Wind size is normal, etc.

When chest type freezer breaks down, wiser course of action when oneself check first, premise is to want to choose and buy the product with qualified quality for oneself. If you want to buy high-quality chest freezer with reasonable price, Meibaijia Electrical Technology Company can provide you with the best products.
