Because polyurethane sheet has excellent thermal insulation performance， it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.
The refrigerant charge is insufficient. At this time，Fruit and vegetable fresh-keeping cold storageAffordable National hot sale just add enough refrigerant.
TbIf necessary，Polyurethane spraying warehouse install a filter on the compressor return pipeline to prevent dirt in the system from entering the compressor and remove water in the system.
sInstallation of refrigeration equipment. The refrigeration system of the cold storage includes evaporator and units outside the cold storage. All equipment shall be installed in accordance with the construction specifications， and corresponding protection measures shall be taken for the installed equipment.
Fruit and vegetable refrigeratorThe market is rising
After cooling down steadily，Cold storage installation - cold storage installation - cold storage construction - fruit preservation cold storage medicine cold storage - Anhui Fuyang Xinyuan Refrigeration Technology Engineering Co., Ltd check all parts of the refrigeration system and discharge
The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel， which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.
Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large，Fruit and vegetable fresh-keeping cold storageAffordable National hot sale so the amount of thermal insulation materials is large，Polyurethane spraying warehouse and the dry consumption of cold food is also large; For the low-temperature warehouse，Polyurethane spraying warehouse the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level， it is impossible to deal with it， which is easy to cause horizontal freezing and swelling.
