We Manufacture All Sizes Unit Cooler for Cold Room

We customize all types unit cooler ( evaporator unit, indoor unit) with different sizes and materials, fan diameter is 300~700mm or even more, contact us for details.

Chłodnica jednostki

Unit cooler is also called evaporator unit, indoor unit, is an essential refrigeration equipment for Zimny ​​pokój.

It is mainly composed of 5 important components: cooling and heating exchange pipe, axial flow fan, liquid separator, defroster, and water tray.

It relies on the axial flow fan forcing the air (in the cold room) to flow through the cooling exhaust pipe of heat exchange aiming to cool the air, finally achieve the purpose of lowering the cold room temperature.

Unit Cooler Fin

Fin color is optional: Bule, golden, and natural.

Depending on the ambient temperature, unit cooler will use different fin spacings.

Commonly used fin spacings for unit coolers are 4mm, 4.5mm, 6~9mm, 10mm, 12mm, and 16mm.

The lower the cold room temperature, the larger the fin spacing required. Incorrect fin spacing means the fin frosting speed will be fast, which will quickly block the air passage, and making it difficult to cool the cold room Meanwhile , result in the compressor inefficiently and increasing the power consumption of the whole refrigeration system.

Fin Spacing

#1. Średni / High temperature cold room (0℃~20℃)

Such as workshop, shady storage, fresh-keeping storage, air conditioning storage, ripening storage, itp., the fin spacing should be 4mm or 4.5mm.

Rozstaw płetw

#2. Chłodnia o niskiej temperaturze (-16°C~-25°C)

Such as low-temperature freezer, low-temperature logistics warehouse, the fin spacing should be 6mm~9mm.

#3.Quick freezing cold room (-25℃~-35℃)

Fin spacing is generally 10mm~12mm. If the humidity of the quick-frozen goods is high, had better select the unit cooler with variable fin spacing, and the fin spacing on the air inlet side can be 16mm.

Notatka: In some occasions, Can’t select the fin spacing simply by temperature, such as the rapid in/out of meat and vegetables, Proszę Skontaktuj się z naszym sprzedawcą for unique solution.

Unit Cooler Coil

# Array ways of unit cooler coil

Tam są 2 array ways of unit cooler : cross and positive.

In same cooling area and wind speed, the heat transfer efficiency of cross array is better than positive array; Jednakże, the cross array produces more resistance when the air flows than the positive array. When use the same fan, the heat exchanger air volume of cross array is smaller than positive array.

At same heat exchange area, if the coil arrangement is different, the product’s heat exchange volume is different.

Unit Cooler Defrosting

Causes of frosting

#1. Incorrect installation Position

If installed above the Drzwi do chłodni. When open the door, the hot air outside the cold room is directly sucked into the inside of the unit cooler, and the water vapor is also condensed on the cooler housing and the fan grille.

Unit cooler frosting

#2. Higher relative humidity (RH)

The cold room door is frequently open and close when discharge the goods. Because the door is long time opened resulting in the continuous intrusion of huge external hot air into the cold room.

#3. Incomplete defrosting

Due to the insufficient defrosting time and the unreasonable position of the defrosting reset probe, the evaporator will be turned on when the defrosting is incomplete, and the partial frost layer of the evaporator will become icing after several cycles finally become larger and larger.

Defrosting Ways

#1. Manual defrositing

Pay attention to safety first during the manual defrosting process, do not damage the refrigeration equipment.

#2. Water defrosting

Pouring water on the evaporator surface, then the temperature of the evaporator rises, forcing the frost attached to the evaporator surface to melt. This way is carried outside the evaporator, so must treat well the water flow in the process to avoid affecting the normal use of the refrigeration equipment.

#3. Electric heating defrosting
Install electric heating tubes or heating wires inside the unit cooler fins to defrost by the current thermal effect. This way can intelligently control the defrosting through a micro-computer controller, which can greatly reduce labor time and cost.

#4. Thermal fluid defrosting
Use the refrigerant vapor (with higher temperature) discharged from the compressor to enter the evaporator after passing through the oil separator, meanwhile use the released heat when the thermal fluid is condensed to melt the frost on the evaporator.

Unit Cooler Cooling Capacity Calculation

Do you know how to select the correct unit cooler cooling capacity for your cold room?

Chiller Cold Room

The load per cubic meter is calculated as 75W

#1. If cold room Volume < 30m3, multiply by factor A=1.2

Na przykład: Cold room volume is 90m3, so you need to choose unit cooler cooling capacity: 90*75*1.2=8,100W

#2.If 30m3≤Volume<100m3, multiply by factor A=1.1

#3. If Volume≥100m3, multiply the factor A=1.0

Freezer Cold Room

The load per cubic meter is calculated as 70W

#1. If cold room Volume < 30m3, multiply by factor A=1.2

Na przykład: Cold room volume is 90m3, so you need to choose unit cooler cooling capacity: 90*70*1.2=7,560W

#2.If 30m3≤Volume<100m3, multiply by factor A=1.1

#3. If Volume≥100m3, multiply the factor A=1.0

# Installation Rules:

1. Airflow should cover the entire room.

2. Forbidden to install the unit cooler above the door.

3. Aisles and shelves shouldn’t block the passage of air supply & return air.

4. The piping distance from the unit cooler to the compressor should be the shortest.

5. Keep the distance to the drain pipe the shortest.

# Installation distance:

S1The distance between the wall and the unit cooler coil is >500mm.

S2For ease of maintenance, the distance from the wall to the terminal plate shall be >400mm.
