Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.

Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be ~ seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; TR time relay is broken (relay unit).

AyAmmonia filling leak test: ammonia filling leak detection can be carried out after system blowdown and pressure leak test. The purpose is to improve the air tightness of the system and lay a good foundation for the work of ammonia filling and thermal insulation materials of the system. After air leakage detection,Fresh vegetables and fruits cold storageHow to operate during construction some obvious leakage points can be found. However,Cold storage due to the poor air permeability, the leakage points blocked by dirt along the tiny sand holes are not easy to be detected. Therefore,Cold storage installation - cold storage installation - cold storage construction - fruit preservation cold storage medicine cold storage - Anhui Fuyang Xinyuan Refrigeration Technology Engineering Co., Ltd ammonia must be filled. In addition to good permeability, ammonia also has odor and is easy to be found,Fresh vegetables and fruits cold storageHow to operate during construction At the same time,Cold storage phenolphthalein test paper can be used for leak detection because it is rose red in the presence of ammonia.

aThe cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII,Cold storage PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference, so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.

If the cold storage is in the building, the load-bearing of the cold storage should be considered. That is, after the fruit is loaded in the cold storage, whether the floor can bear such weight.

The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance, insulation effect and moisture-proof effect, so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, and the cold storage management personnel can timely and effectively open and close the door when entering and leaving, so as to avoid the loss of refrigeration capacity of the cold storage.

At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.
