Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time， which not only has excellent fire resistance，How much does it cost to install a cold storageOn new trends but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification，Combined cold storage with fixed length， cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam，Cold storage installation - cold storage installation - cold storage construction - fruit preservation cold storage medicine cold storage - Anhui Fuyang Xinyuan Refrigeration Technology Engineering Co., Ltd and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane， polystyrene grease，How much does it cost to install a cold storageOn new trends etc. Polyurethane is non hygroscopic and has good fire resistance，Combined cold storage but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance，Combined cold storage but the cost is low.
Regular oil discharge， descaling and air discharge: when there is a .mm thick oil film in the evaporator coil in order to maintain the set temperature requirements， the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm， the condensation temperature will rise by ℃ compared with the original temperature， and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa， the power consumption will increase by about . It can be seen that it is cold
JbThe electrical equipment of the fresh-keeping warehouse equipment shall be prevented from moisture return to prevent it from being caused by power failure.
fImproper adjustment or blockage of throttle valve， the refrigerant flow is too large， the evaporation pressure and evaporation temperature also increase， and the decline rate of warehouse temperature will slow down; At the same time， when the throttle valve is opened too small or blocked， the refrigerant flow will also decrease， the refrigeration capacity of the system will also decrease， and the decline rate of warehouse temperature will also slow down.

The shelves in the warehouse shall have sufficient strength and rigidity.
It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day， and the door of the cold storage must be locked.
The refrigerant charge is insufficient. At this time， just add enough refrigerant.
