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.

Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.

San-Rafael-Arriba.Does the unit location meet the relevant conditions? Whether the heat dissipation and pipe length can meet the requirements.

Regular oil discharge descaling and air discharge: when there is a 0.1mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by 5 ℃ and the power consumption will increase by more than 10; When the scale on the water pipe wall in the condenser reaches 5mm, the condensation temperature will rise by 8 ℃ compared with the original temperature,San-Rafael-ArribaInstallation of fruit cold storage, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches 0.196mpa, the power consumption will increase by about 1

.During installation, the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.

Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.

We should implement regular maintenance and daily maintenance, professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage, large quantity, excellent quality and low price, fire resistance - Waterproof - high temperature resistance strong and durable, safe and reliable, and maintain the operation rate of the compressor.

Regular oil discharge, descaling and air discharge: when there is a 0.1mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by 5 ℃ and the power consumption will increase by more than 10; When the scale on the water pipe wall in the condenser reaches 5mm, the condensation temperature will rise by 8 ℃ compared with the original temperature, and the power consumption will increase.

Set the parameters and valve opening in the computer according to the frosting and use of the fresh-keeping warehouse.

Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature 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.

Create brilliance.During installation, the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.

The two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.

The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.

The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof, waterproof and corrosion resistance make it have better air resistance and water vapor resistance, and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.

target.Simple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, so as to cool the refrigerant, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, so it can only be used in less places,San-Rafael-ArribaHow much does it cost to build a small fruit preservation cold storage, such as brine ice making and cold storage with constant temperature requirements.

Do not cut off the main power supply to shut down the unit unless it is an emergency; If the unit is out of service for a long time in winter, turn off the unit first, then turn off the main power supply and oil heater, and drain the water in the system.

Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.

San-Rafael-Arriba.The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.

Installation of box and operating device: the design of box shall be reasonable, and the appearance quality shall meet the requirements of beauty and practicality. All buttons, electrical switches, etc. shall be reliable, long-term cold storage installation, cold storage construction, medical cold storage, 20-year-old brand, price advantage and quality guarantee! Easy to identify and operate. The indicator light shall be simple and clear. The device and each switch shall be installed on the upper side outside the warehouse door, which is easy to operate, read data and not easy to be damaged, and shall be reliably fixed. The device box is installed on the door frame plate on the door opening side. The center line of the box overlaps the center line of the door frame plate. The bottom of the box is 1800mm above the ground and is reliably fixed. The lighting lamp and door frame wire switch in the warehouse are installed directly below the device, and the height of the bottom edge of the switch box is about 1400mm.

The bubble density is 38 kg to 40 kg / m3 per cubic meter, and the steel plate thickness generally needs to be more than 0.4 mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect,San-Rafael-ArribaWhich cold storage is easy to install, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.
