What are the precautions for installation in the cold storage plate?

Reasonable connection and installation of evaporator, radiator, copper tube, thermostat, wire and cold storage host can make the cold storage unit and refrigeration system work safely and stably.

The installation points are as follows: 1 The cold storage unit should be installed as close as possible to the evaporator, which is easy to maintain and has good heat dissipation. If you move out, you need to install a canopy, and shockproof gaskets should be placed at the four corners of the cold storage unit, so that the installation level is firm and it is not easy to be touched.

2 The installation position of the radiator of the cold storage unit should be as close as possible to the cold storage unit, preferably on the upper side of the cold storage unit. The installation position of radiator has the best heat dissipation environment. Do not point the suction port at the exhaust port of other equipment, especially oily gas. The air outlet should not be short-circuited and face other windows (especially residents' windows) and equipment. 2M high from the ground, and the installation level is firm.

3 Copper pipes of cold storage units All copper pipes need to be wound together with wires in the same direction through insulating pipes, and the pipes should be as straight as possible and fixed in sections.

4 wire discharge All wires should be tied with air conditioning cable ties and protected with corrugated hoses or trunking. The temperature display wires should not be arranged together with the wires as far as possible.

5 The condenser and evaporator connected to the refrigeration system of the cold storage unit have been sealed at the factory, so there should be pressure to check whether there is any leakage when unsealing. Both ends of the copper tube in the factory should be sealed at any time during construction to prevent dust from entering the tube. The condenser → cold storage host → evaporator and copper tube are connected by welding, and the interface is firm and beautiful. According to the performance of each electrical appliance, the conductor is configured, the diameter of the conductor meets the requirements, and the joint is firm. If you need to protect the tube, you can't save it, and the power supply is connected correctly. When the conductor enters the hole of the evaporator junction box, it needs to be sealed with silica gel. If the lamp is connected above 36V, it needs to be grounded. The electricity in the electrical cabinet of the cold storage unit needs three-phase five-wire system and reliable grounding. The temperature controller of the cold storage unit is fixed on the ceiling of the cold storage, and the probe and the temperature display probe are inserted into the evaporator air return port in the cold storage and hung. The defrosting thermostat of the cold storage unit is also fixed on the ceiling, the probe penetrates into the evaporator air return port in the cold storage, and the probe is inserted into the fin (not close to the electric heating tube). If people can't get on the ceiling of the cold storage, fix the temperature control and defrosting temperature control at the back corner of the evaporator of the cold storage and seal all the connection points, as above. The balance hole (pressure equalizing valve) should not be installed in a conspicuous place or on the vertical plate of the air outlet, and the height should be 200MM away from the upper part of the vertical plate of the cold storage. All parts that pass through the cold storage plate and the gaps between the cold storage plate and the parts should be sealed with sealant.

Code for installation of evaporator of refrigeration equipment

Installation contents of 1: First, open the lifting screw hole, and open the copper pipe and wire hole. The last two holes should be trimmed to prevent hidden dangers caused by quick opening. The back of the evaporator with self-made drainage pipe is located 300mm away from the vertical plate, and the drainage hole of the evaporator is vertical to the preset drainage hole on the vertical plate, with a height difference of 250mm. Take the frozen refrigerator as an example, the drainage heating wire passes through the drainage pipe, and the heating part of the drainage heating wire can only reach 50 mm in the warehouse board.

2 When hoisting, pay attention to that the evaporator air inlet should not face the cold storage door, the evaporator should be hung at the longest end of the cold storage, and the evaporator air outlet should not face the door (the evaporator should be centered during maintenance).
