The drainage at the outlet of the cooling fan， the drainage of the volatile cooler and the road drainage of the refrigerated warehouse storing food or drinks shall not be immediately connected with the sewage and wastewater pipeline system software， but indirect drainage shall be adopted. For the flushing (thawing) water drainage of each layer in the double-layer cold storage， an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.
LahoskBecause our large-scale fresh-keeping warehouse is generally composed of many thermal insulation boards， and the gap between each board is the place that needs maintenance. During construction， these gaps will generally be sealed with sealant， but if it is found that there are seal failure departments in the fresh-keeping warehouse during use， they need to be repaired in time.
Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage 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.
RicahCold storage plate features: good thermal insulation performance， light weight， high strength， corrosion resistance， anti-aging beautiful appearance.
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.
Now let"s analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions， when the water vapor with high indoor temperature migrates outdoors， it is impossible to condense in the wall due to the obstruction of the cold storage.
The wide， light and thin walls are made of rigid polyurethane foam at the same time as structural materials， making the whole structure have the advantages of light weight， large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit， which allows the use of thinner plates during construction and saves building space.
Ammonia 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 fresh-keeping warehouse system and lay a good foundation for the system to fill ammonia and wrap thermal insulation materials.
The selection of equipment for the construction of equipment cold storage is closely related to the size， type and budget of the cold storage.
Safety and healthRelative humidity maintenance of quick-frozen warehouse: humidification of quick-frozen warehouse is very important， from centrifugal humidification to high-pressure micro fog humidification， gas-water mixed humidification， to the current ultrasonic humidifier. The utility model has the advantages of small particles， uniform humidification no freezing and blocking， which is essentially different from other humidifiers in the market: fully closed circulation and no dirty blocking. The air conditioning humidifier we produce is specially designed for all kinds of vegetable and fruit quick freezing warehouses， that is， take the gas in the warehouse， return to the warehouse through the humidifier and isolate it from the outside air.
Moreover，LahoskInstallation price of small cold storage， polyurethane does not produce harmful gas at high temperature.
Installation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse， the distance between the box bottom and the top of the warehouse must be & amp; gt; mm; The electrical box can be fixed on the building wall or on the angle steel frame.
Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment， use the volatilization of the refrigerant to immediately cool the air in the air， and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed， small heat conduction temperature difference and simple system software， so it is widely used.

In the cold storage project， the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project， we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature， attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.
LahoskKg to kg / m， and the steel plate thickness generally needs to be more than . 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， it can foam cold storage insulation materials with appropriate density and good thermal insulation effect， 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，LahoskCold storage installation cold storage installation， the polyurethane board has very good thermal insulation performance and does not absorb moisture.
Watertight polyurethane rigid foam has low water absorption， good permeability to water vapor， and state of foam pores. It is not connected with each other， and the obturator rate is more than %. It is a dense microporous foam material， which is more dense than the surface of the air， and is not easy to permeate. It is an hydrophobic material.
However， long-term continuous operation will inevitably lead to equipment aging， so reasonable maintenance is particularly important.
