1.1 Industrial Cold room panel material

The insulation material of OnlyKem Industrial cold room is polyurethane foamed composite insulation boards with spray-coated steel plates or stainless steel plates, with different thickness for different room temperature. Insulation material is flame-retardant, non-chlorofluorocarbons. Add a certain proportion of reinforcing materials to improve performance, but will not therefore reduce the thermal insulation properties.

1.2 Industrial Cold room panel installation requirement

The seam between cold room panels must be sealed well, and the joint seam between the two panels is less than 1.5mm. At the same time, the structure is required to be solid and reliable. After assembling, all the joints of the cold room panels should be coated with a silicone sealant. Following drawing for your reference.

When the roof panel span exceeds 6m or the ceiling of the cold storage is heavy, the ceiling of the cold storage must be hanged. The position of the bolts should be selected from the middle point of the cold room panel. In order to keep the cold room panel to be as even as possible, the mushroom type screw, hanger and U-shaped channel steel must be used for fixing according to the diagram.

1.3 Industrial Cold room door

1) The door frames of low-temperature industrial cold room should be embedded with electric heating to prevent the sealing strips of the doors from being frozen. When electric heating is used, electric heating protection devices and safety measures must be provided.

2) The industrial cold room door has a door lock and the door lock has a safety unlocking function, we call it escape device.

1.4 Accessories

1) The interior of the warehouse is equipped with moisture-proof and explosion-proof LED lamps, which can work at low temperature. The lampshade should be damp-proof, anti-corrosion, anti-acid and anti-alkali. The degree of lighting in the industrial cold room should meet the requirements for the entry and exit of goods.

2) Pipeline holes must be sealed, moisture-proof and heat-insulated.

3) Industrial cold room should have a pressure balance device to prevent and eliminate the pressure difference between the cold room and outside.

4) Control panel requires installation near the Kumen.

5) Drainage floor drains must be installed in the freezer to allow the sewage to drain when cleaning the cold storage.

2.1 Installation of air cooler

1) The installation position of the air cooler shall be far away from the cold room door, and in the middle of the wall, the air cooler shall be kept horizontal;

2) The cooling fan is mounted on the top panel or the steel frame of warehouse, and its fixing must use a special nylon screw (material nylon 66) to prevent cooling capacity leak;

3) When fixing the air cooler with bolts, it is required to install wooden blocks with a length of more than 100mm and a thickness of more than 5mm on the top panel to increase the load-bearing area of the storage panel.

4) The distance between air cooler and the back wall is 300-500mm.

5) The wind direction of the air cooler cannot be reversed to ensure that the cooler blows outward;

6) When the refrigerator defrosts, the fan motor must be disconnected to prevent hot air from blowing into the cold room when defrosting;

7) The height of goods should be at least 30cm below the bottom of the air cooler.

2.2 The installation of refrigeration pipe

1) When installing the expansion valve, the temperature-sensing package must be fastened to the upper part of the horizontal return pipe, and ensure good contact with the return pipe. Heat insulation should be provided outside the return pipe to prevent the temperature from being influenced by the temperature of the storage tank.

2) Install the oil return bend at the bottom of the riser pipe before the chiller return pipe climbs out of the warehouse;

3) When a processing room shares a unit with a cold room or medium-temperature cabinet, an evaporation pressure regulating valve must be added before connecting the re-circulating line of the refrigerated processing room with other refrigerating or medium-temperature cabinet pipes;

4) Each cold room must be equipped with separate ball valves on the return air pipe and the liquid supply pipe for debugging and maintenance.

2.3 The installation of water drainage pipe

1) Drainage pipelines running in the cold room should be as short as possible.

2) The cold room’s drainage pipe should have a certain slope, so that the defrost water can be smoothly discharged outside the storehouse;

3) The cold storage with working temperature less than 5°C must be equipped with insulation pipe (thickness greater than 25mm) in the drain inside the warehouse;

4) Heating wire must be installed in the freezer drain;

5) Connection pipes outside the cold storage must be installed with drainage traps to ensure a certain liquid seal in order to prevent large amounts of hot air outside the library from entering the cold storage.

Air Cooled Condenser

Air Cooled Condenser is important part in whole refrigeration system, it is the heat part in whole refrigeration system, there are several types, today we discuss the air cooled type, In this systems involving heat transfer, a condenser is a device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. In so doing. Condensers can be made according to numerous designs, and come in many sizes ranging from rather small (hand-held) to very large (industrial-scale units used in plant processes). For example, a cold room uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants and other heat-exchange systems.

A condenser unit used in refrigeration systems typically has a heat exchanger section to cool down and condense incoming refrigerant vapor into liquid, a compressor to raise the pressure of the refrigerant and move it along, and a fan for blowing outside air through the heat exchanger section to cool the refrigerant inside. A typical configuration of such a condenser unit is as follows: The heat exchanger section wraps around the sides of the unit with the compressor inside. In this heat exchanger section, the refrigerant goes through multiple tube passes, which are surrounded by heat transfer fins through which cooling air can move from outside to inside the unit. There is a motorized fan inside the condenser unit near the top, which is covered by some grating to keep any objects from accidentally falling inside on the fan. The fan is used to blow the outside cooling air in through the heat exchange section at the sides and out the top through the grating. These condenser units are located on the outside of the building they are trying to cool, with tubing between the unit and building, one for vapor refrigerant entering and another for liquid refrigerant leaving the unit. Of course, an electric power supply is needed for the compressor and fan inside the unit.

Air cooled condenser application:
Air cooled – If the condenser is located on the outside of the unit, the air cooled condenser can provide the easiest arrangement. These types of condensers eject heat to the outdoors and are simple to install.
Most common uses for this condenser are domestic refrigerators, upright freezers and in residential packaged air conditioning units. A great feature of the air cooled condenser is they are very easy to clean. Since dirt can cause serious issues with the condensers performance, it is highly recommended that these be kept clear of dirt.

Other Types of Condensers
In the world of Heating, Ventilation, and Air Conditioning (HVAC), condensers happen to be a topic of great importance. Instead of confusing information, the goal is to provide some basic information on the different types of condensers and their applications.
There are other condensers except air cooled used in HVAC systems
Water-cooled condenser
Evaporative condenser
Applications:
Water cooled – Although a little more pricey to install, these condensers are the more efficient type. Commonly used for swimming pools and condensers piped for city water flow, these condensers require regular service and maintenance.
They also require a cooling tower to conserve water. To prevent corrosion and the forming of algae, water cooled condensers require a constant supply of makeup water along with water treatment.
Depending on the application you can choose from tube in tube, shell and coil or shell and tube condensers. All are essentially made to produce the same outcome, but each in a different way.
Evaporative – While these remain the least popular choice, evaporative condensers can be used inside or outside of a building and under typical conditions, operate at a low condensing temperature.
Typically these are used in large commercial air-conditioning units. Although effective, they are not necessarily the most efficient.
Prior to beginning your install, make sure you choose a condenser that will provide you with the most efficient use.

Ice Cream Cold Room Freezer In Spain
https://goo.gl/skDgvZ

Our typical ice cream freezer solutions are between -18~-25°C.  Why is freezing so important to consider?

Ice cream has some unfrozen water associated with it at the typical serving temperature range of -15°C to -18°C. Without this unfrozen water, the ice cream would be too hard to scoop. On the other hand, if the freezing point is not depressed enough, too much water will be frozen and the resulting ice cream will be too hard both for processing and subsequent consumption.
