What problems should be paid attention to in cold storage installation and construction?


The cold storage chiller, temperature controller, control circuit, valves, pipelines, cold storage host and other reasonable connection and installation, and the correct installation process can ensure the safe and stable operation of the cold storage unit and refrigeration system. So what issues should be paid attention to when installing the cold storage?

  1. The cold storage unit is installed as close to the evaporator as possible. It is easy to maintain and has good heat dissipation. If it is moved outside, it needs to install a canopy. The cold storage unit has four corners. It is necessary to install anti-vibration gaskets, the installation level is firm, and it is not easy to be touched by people.

  2. All the copper pipes of the cold storage unit copper pipe discharge should be separately put through the insulation pipe and the wires in the same direction should be wrapped together with air-conditioning ties, try to straighten the pipeline and fix it in sections .

  3. The radiator of the cold storage unit should be installed as close to the cold storage unit as possible. It is best to place the cold storage unit in the upper position, and the radiator installation position has the best heat dissipation environment , The suction port should not face the outlet of other equipment, especially oily gas, and the outlet should not be short-circuited and facing other windows (especially residential windows) and equipment. The ground should be 2M high and the installation level should be firm.

  4. Cold storage unit piping and line installation: all copper pipe welding, pressure test and blowdown are completed, Install the thermal insulation pipe, pay attention to use glue to stick all the connection gaps of the thermal insulation material firmly, and wrap it with a cable tie. The wires and cables should be protected by pipes or troughs separately, and fixed brackets should be set up in accordance with the specifications. The weak current signal line should be routed separately from the strong current, and shielded if necessary.

  5. Because the cold storage units and air coolers are pressure-sealed in the factory, there should be pressure when opening the package, and it can be checked for leaks. The factory copper pipe should be at both ends There are dust sealing measures, and you should also pay attention to sealing at any time during construction to prevent water and dust from entering the pipe. The condenser, cold storage host, and air cooler are connected by copper pipes, and the joints are firm and beautiful by welding.

  6. Configure the wires according to the performance of the electrical appliances, the wire diameter meets the requirements, the joints are firm, and the pipes need to be protected to avoid saving, and the power connection is correct. The wire enters the evaporator junction box hole and needs to be sealed with silica gel. If the lamp is connected to 36V or more, a grounding wire is required. The electrical cabinet of the cold storage unit needs a three-phase five-wire system and reliable grounding.

  7. The temperature display probe of the cold storage unit penetrates into the return air port of the evaporator in the cold storage and is suspended in the air. The defrost temperature probe of the cold storage unit is additionally perforated into the return air port of the evaporator in the cold storage. Insert into the fin (not close to the heating tube).

   8. Balance hole (pressure equalizing valve, also called balance window), do not install on the conspicuous place and the vertical board of the air outlet, the height is 200mm from the upper part of the cold storage vertical board hole. For all parts that penetrate the cold storage board, the gap between the cold storage board and the components must be sealed with sealant.
