CHAPTER 1 PRODUCT BRIEF This product is a newly developed frost-free refrigerator of our

company.

The product's external appearance is special and decent

sculpting.

It is the whole box hull structure, poured foam behind, ensured

foamed layer thickness equality. So the heat preservation

function is more excellent

It is the whole foamed door structure, designed to a thin door

gasket structure that can keep cold air effect better and with

maximum limit attain economy energy effect.

In the frozen room door racks are used that it can enlarge the

storage space and increment to store.

In the refrigerate room can rack is used that it can easily store

and take to take to easily pull a soft beverage product such as

can.

In the cold system wings slice type evaporate is used that it

can spread hot efficiency increment and make cold effectively.

Control the system accords with American UL safe attestation

request, you can trust an usage please.

Three, break down analysis:

一、refrigerate room isn’t cool or is cool not better

Break down analysis:

1)the fan is bad or there is the stopper and its rotate speed is

much low(it is much more possibility in after two kind.)

2)Refrigerator air road is not free so that breeze is much little

or not.

3)Frost on the evaporate is thick ,or the ice is much more(see a

behind reason analysis)so that refrigerator room is not cold or

cold much better.

4)Refrigerant lacks or leaks

5)The compressor doesn't operate or is bad(see a behind

reason analysis).

6) The door is not closed completely or the door gasket does

not seal properly.

7)Too much food is stored so that cool air dosen’t flow much

better.

二、The frozen room room isn’t cool or is cool not better


1) the fan is bad or there is the stopper and its rotate speed is

much low(it is much more possibility in after two kind.)

2) Refrigerant lacks or leaks

3) Frost on the evaporate is thick ,or the ice is much more(see

a behind reason analysis)so that refrigerator room is not cold

or cold much better.

4) The compressor doesn't operate or is bad(see a behind

reason analysis).

5) Too much food is stored so that cool air dosen’t flow much

better.

三、Frost on the evaporate thick or the ice much more


Frost on the evaporate thick：

1) The door gasket does not seal properly so that the

compressor doesn't shut down

2) Door is opened too frequently and much water in the foods

is placed refrigerator.

3)The defrost timer doesn’t operate properly.

4)The temperature fuse doesn’t operate properly.

5)The electrical connection doesn’t operate properly.

The ice block up:

There is much water in the system.There need replace a new

filter

四、The compressor doesn't shut down


1) The door is not closed completely or the door gasket does

not seal properly.

2) The electrical connection doesn’t operate properly.

3) The temperature fuse doesn’t operate properly.

4) the fan is bad or there is the stopper and its rotate speed is

much low

The compressor doesn't start


1) The electrical connection doesn’t operate properly.

2) The starter is bad.

3) The temperature fuse is bad

Noise abnormality


In the normal circumstance, compressor is operating and fan

blade is operating,which cause noises. But sometimes noises

isn’t normal ,reason is:

Check if the compressor is installed properly?

Check if interference happens which the fan blade with

surroundings the structure

三 Control system

1. Electricity principle diagram

2.Defrost work principle

It is time to begin from last defrost period,defrost timer port 3

and 4 are connected, the compressor begins to operate,

between the compressor is operated ,the same time the motor

of the defrost timer is operated,when it 16 hours that is the time

of the compressor s operated ,under the drive of defrost timer

motor defrost timer port 3 and 2 are connected ,the

compressor is stopped and auto-defrost is processed.

After getting in to auto-defrost, because the temperature of

the evaporator surface is low, over-temerature control of

heater is connected and defrost timer motor is stopped, defrost

heater is operated.When the temperature of cool evaporator is

rised to about 8 ℃ , over-temerature control of heater isn’t

connected and defrost timer is stopped. The defrost timer

motor is processed after about 7 minutes under the drive of

defrost timer motor defrost timer port 3 and 2 are connected

again,and it is time to end of defrost period, and the

compressor is operated.Such as goes round and round.
