Deep temperature cold has the effect of inhibiting the growth of microorganisms, mold development so that applications in the food preservation, agricultural products, marine products, marine production … From then on, we Refrigeration systems are applied in many industries such as processing technology, preservation, machine design, fabrication …
To ensure that the refrigeration system is operating properly and running at the required cold temperature, the installation of the equipment must be in accordance with the required specifications.
Installation of insulation panels
When installing the refrigeration system, it is important to note that cold temperatures are guaranteed, without heat loss, depending on the insulation. Install insulating panels on eels ventilated with concrete or card bricks, about 100-200mm high. To balance internal and external pressure on the wall of the pressure relief valve.
Installation of condensing equipment
The condenser is installed on the top, above the concrete platform, the support or immediately above the container into 01 cluster. The installation location of condensing equipment need to cool easily to escape heat to the environment, not affecting people and production process.
Installation of evaporators
Evaporator: Usually installed inside the house on concrete supports.
Fishbone Fish Cooler: Layers of cooling chambers between salt surfaces make the process faster and less heat loss. Arrange water flow in the direction from the top to the bottom of the heat exchanger, need to provide fluid from the bottom and the steam goes out.
Indoor air cooler: note the reach of the wind exits the indoor unit is 10m. If the length is large, it is necessary to arrange additional indoor unit or install the air duct system on the output of the indoor unit. Leave a minimum of 500mm behind the indoor unit.
Installation of refrigeration compressors
When transporting attention should only be hooked to the designated location, not be accidentally hooked to the pipe or body to prevent scratches and damage the compressor. When installing the compressor, attention should be paid to the following issues: operation, inspection, dismantling, piping, repair, ventilation and illumination.
For small machines when installing the system, it is necessary to install the iron frame or on the condenser. The foundation must be at least 100 mm above the ground. The resistance of the foundation must be at least 2.3 times the compressor load including the motor.
The minimum distance from the foundation to the foundation is at least 30cm. If installed on the upper floor, it must be placed on the anti-vibration platform and inertia pad. After putting the machine into the installation position, use the ruler to check the horizontal level, check the coaxial level of the belt. Do not push the straps close to the pulley, loosen the distance between the motor and the compressor and then the belt, then turn the bolt to push the slide. Check strap tension. Can remove the drive of the compressor by pipeline using a soft tube connected to the compressor.
Installation of water pipes
Cooling water pipes, stripes must use zinc-coated steel tubes, outside the blue paint. For piping from the indoor unit and other equipment, PVC pipes can be used, either insulated or non-insulated, depending on the installation location. Water treatment should use stainless steel pipe to cover the heat.
Installation of liquid medium
During the installation of the refrigeration system, the construction and installation of the pipeline is carried out as follows:
1. NH3 conduit
– Pipe welding: Before thoroughly sanitized, bevelled in accordance with regulations. The spot should be located where it is easy to see when the problem occurs.
– Bending: The bending radius of the tube is large enough to prevent crimp bending.
– Insulation: Insulate steel pipes made of styrofoam or polyurethane. The thickness is about 50-200mm, depending on the size of the pipe, the bigger the insulation the thicker and vice versa. The pipe insulation as follows: Anti-rust paint, Insulation, waterproof paper, stainless steel (or aluminum cover).
2. Freon Pipes
– Material: steel pipe or copper pipe.
– Freon should be dry, avoid moisture.
Cut off Freon tubes with specialized cutters or small cutters.
– The fluid from the top of the machine, the refrigerant from the bottom and the back often have a solution of oil. In addition, the suction pipe should tilt towards the compressor so oil can flow back. This is a very important point in the installation of refrigeration systems.
Installation of blocking valve
Installation in an easy to operate position, quick operation, can lie on the horizontal or vertical lines, if the horizontal tube, the valve arms should be mounted up the path. The opening of the valve is sufficient to operate and repair, and the valve should be removed when necessary. On the valve body there is an arrow indicating the direction of movement of the media, so attention and installation in the right direction.
