Tres-RiosCold Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.
The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, it needs to be checked in time.
Sherwood-Park.The volume of the controlled atmosphere warehouse the size of the controlled atmosphere warehouse shall be calculated according to the volume occupied by the storage products stacked in the controlled atmosphere warehouse,Sherwood-ParkPrice of fruit and vegetable fresh-keeping cold storage,Sherwood-ParkRefrigerator manufacturer, plus the aisle between rows, the space between the stack and the wall and ceiling, and the gap between the packaging. After determining the capacity, the length and temperature of the controlled atmosphere warehouse shall be determined. The design of the controlled atmosphere warehouse shall also consider the necessary auxiliary buildings and facilities, such as workshop Packing and sorting room, tool warehouse and loading and unloading platform, that is the top, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.
.The products stored in the medical cold storage project must be managed by color code, so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.
Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity, ton, cubic meter, frame, box); What products are stored in the built cold storage? The actual storage temperature, storage time and setting temperature can be indicated by specific regulations; If your cold storage becomes larger, you need to master your individual storage volume the temperature of goods in and out of the warehouse, the frequency of opening and closing the door, etc. If this is clear it is the selection of raw materials, such as refrigeration compressors, refrigeration units, industrial cooling fans / pipe slots, thermal insulation materials, coolers, temperatures and other refrigeration equipment.
Preparation, prepare the project planning of cold storage, and prepare the construction site and construction materials. All kinds of materials for cold storage construction are customized according to the needs of customers. Sort out the construction site that meets the requirements, transport all installation materials to the construction site, check the material quality and model, and start the installation of cold storage after confirmation.
Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.
Degree, suction temperature, motor temperature, crankcase temperature and temperature in front of the valve,Sherwood-ParkPreservation technology of vegetables in cold storage, observe the frosting of the evaporator and valve, and observe the oil level and color change of the oil mirror. Whether the sound of equipment operation is abnormal.
Features of quick freezing warehouse: the quick freezing technology is advanced, the frost free quick freezing method is adopted, the famous brand compressor and refrigeration accessories are configured, and the automatic frost is adopted. The method can only be used by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the 21st century.
Safety and health.The service life of the cold storage depends on the quality of the refrigeration equipment, but it also has a great relationship with the proper daily management and maintenance after the installation of the cold storage. Many times, people often ignore the latter point. In daily life, as long as we maintain and maintain the cold storage regularly, we can greatly improve the service life of the cold storage and reduce the cost.
In order to ensure the safety of construction and cold storage operation, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (100mm thick) has a very large span of 3M, and the polyurethane top storage plate (100mm thick) has a span of 5m.
Frozen and refrigerated storage began to change to shelf and pallet storage to complete the goods according to & ldquo; First in first out & rdquo; It is conducive to improve the quality of commodity storage and reduce loss.
According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site, whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration, product stacking, temperature, etc. are used to determine the size and location of the cold storage room, so that it can become a whole.
Create brilliance.Here we focus on polyurethane. Polyurethane is an ideal cold storage material in the cold storage project. Superior bonding properties make the foam and metal panels form a solid whole so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, and then solidified and pressed to form a multi shape storeboard, because the metal plate can roll out different waveforms, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance, but also be economical, applicable and environmental friendly. To ensure the smooth progress of our cold storage project, we should not only inquire about the raw materials of the cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types, namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and 0mm galvanized standard floor plate.
A U-bend shall be installed at the outlet of the air return pipe of the cooling fan. The air return pipeline shall slope towards the compressor to ensure smooth oil return.
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; amp; gt; 100 mm; The electrical box can be fixed on the building wall or on the angle steel frame.
Sherwood-Park.Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.
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. 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
Whether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor, press the black reset button on the pressure controller, and the machine can automatically resume operation.
