ConcepcionSmalAt 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.
For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least 15cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, while the XPS extruded plate with thickness of 100 ~ 150mm can be laid in the high-temperature cold storage.
Belleville.In addition, water shortage or insufficient water in water-cooled machines will increase the exhaust temperature of the fresh-keeping warehouse. The condensation pressure is abnormal and the exhaust pressure of the fresh-keeping warehouse decreases.

The elevator shaft, electronic pit and other places convenient for drainage shall be provided with drainage and equipment to avoid backflow of water.
.When the cold storage is built, the diffusion of water vapor and the infiltration of air shall be prevented. When outdoor air invades, it will not only increase the cold consumption of the cold storage, but also bring moisture into the warehouse. Moisture condensation will damp the heat insulation structure and freeze and damage the cold storage structure. Therefore, it is necessary to set moisture-proof and heat insulation layer, professional cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other products, which have a complete variety, sell well at home and abroad, and have a long service life! Products lead the wire industry. Welcome to inquire, so that the cold storage building has good sealing, moisture-proof and steam isolation performance.

The corner shall be temporarily fixed with 0.5 color plate angle steel; When installing each wall panel, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, and the rivet spacing in the warehouse should be 300mm; When connecting the library plate in the form of eccentric hook connection, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.
Improper adjustment or blockage of throttle valve, too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large, the refrigerant flow is too large, the evaporation pressure and evaporation temperature also increase, 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 assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material, which has excellent thermal insulation performance, storage and circulation effect and reduces operation energy consumption. Of course,BellevilleCold storage manufacturer, more important is the choice of refrigeration system. For example, at present, the refrigeration system of fluorine refrigerant is still the mainstream, it is necessary to calculate the data for the installation of cold storage, and then make a high-quality choice.
Pressure leak test: the pressure leak test of the fresh-keeping warehouse system is the same as that of the sewage blowing working sample, which is required to be carried out by air compressor. If ammonia compressor is used, the method of segmenting and reducing the pressure difference shall be adopted.
The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.
Quality department.In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore, the building materials of the cold storage and the structure of each part of the cold storage should have sufficient frost resistance.
We should implement regular maintenance and daily maintenance, 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.
No matter whether the food cold storage or quick-frozen storage is in use, it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.
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, 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, with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts 10cm thick cold storage plate, 12cm or 15cm 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, and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping, polystyrene grease etc. Polyurethane is non hygroscopic and has good fire resistance,BellevilleHow much is a cold storage, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance, but the cost is low.
Customer first.During the production of cold storage, the cold storage will produce fixed length, width and thickness according to the needs of various cold storage projects. Generally, 10cm thick cold storage plates are selected for high and medium temperature cold storage. The requirements for cold storage engineering plates of low-temperature storage and quick-frozen storage will be higher. Professional cold storage installation,BellevilleFresh frozen food, installation, construction, fruit fresh-keeping cold storage and medical cold storage ensure the quality, Guarantee service. Guarantee quality. Your satisfaction is our pursuit! Welcome to inquire. In this case, use 12cm or 15cm thick library board. When you budget the cold storage project, you can make a reservation according to the specific conditions of your cold storage temperature. If you don't make a reservation for the cold storage plate, you should pay attention to the density of the cold storage plate and the thickness of the steel plate when purchasing the cold storage plate. According to the regulations, the cold storage shall be distributed

The equipment configuration is reasonable and the service life of the quick freezing warehouse is long. The reasonable equipment configuration of the quick freezing warehouse can greatly prolong the service time of the quick freezing warehouse. Some compressors are easy to be damaged when they work at full load for a long time, so we try to use screw parallel units. The great advantage of this unit is that it can turn on all equipment, just like the shift at work, so that the compressor can work and rest in turn.
Belleville.Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic, with small density, light weight strong heat insulation effect and excellent low temperature resistance. However, due to its cold shrinkage, it is not very convenient for installation.
