The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn,apatiteHow much is the installation of vegetable cold storage, the long-term cold storage installation, installation, fruit preservation, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.In order to maintain a constant low temperature in the cold storage,apatiteHow much does it cost to install the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.apatite,Replace the refrigeration oil. After years of service, the refrigeration oil inside the compressor shall be replaced. The oil stain, copper filings, iron filings and impurities caused by secondary wear are mixed in the refrigeration system, which thickens the refrigeration oil, deteriorates the fluidity and performance, reduces the effect, takes a long time, increases the burden of the compressor, and the current will be higher than that of the new machine, This is a bad phenomenon. Replace the refrigerant oil regularly and timely to maintain the good performance of the system, so as to ensure the long-term use of the equipment.There are many application scenarios of cold storage, it provides various cold storage installation, cold storage installation, cold storage construction, medical cold storage, on-site settlement, honest operation, and has offices all over the country for long-term cooperation. Different purposes, functions and designs, so what needs to be understood in cold storage design?Brossard,The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, quantity, frequency, cycle whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..

A large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened, pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.If the controlled atmosphere storage works continuously for more than h, medium maintenance shall be carried out. The condenser, evaporator and cooling exhaust pipe shall be overhauled once a month. The maintenance contents are as follows: the condenser, evaporator and cooling drain pipe are cleaned and adjusted, the cooling water distribution device is cleaned and adjusted, the brine distribution device is cleaned and adjusted, the cooling drain pipe is repaired and the pipe leakage fault is eliminated.Refrigeration system: refrigeration system is the core part of cold storage design. It is the key to determine the economy, environmental protection and performance of cold storage.Potential development,The cooking materials and foods refrigerated in the quick-frozen warehouse contain a certain amount of fat, protein and starch. The existence of these nutrients will make molds and bacteria multiply and grow in large numbers. In order to do a good job in the hygienic management of cold areas and ensure the refrigeration quality of food and cooking raw materials, and the door of the cold storage must be locked.Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, and then pouring concrete or reinforced concrete.

Relative humidity maintenance of quick-frozen warehouse: humidification of quick-frozen warehouse is very important laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively the common operations in the market are: laying the ground with XPS extruded board, 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, and no dirty blocking. The air conditioning humidifier we produce is specially designed for all kinds of vegetable and fruit quick freezing warehouses, which is essentially different from other humidifiers in the market: fully closed circulation, that is, take the gas in the warehouse return to the warehouse through the humidifier and isolate it from the outside air.Application process,There are many kinds of cold storage. According to the material, it can be divided into color steel plate, stainless steel plate and salted steel. Among them, color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is .mm and mm, without color requirements; The thickness of salted steel plate is .mm, without color requirements; The thickness of PE paint baking board is .mm, .mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm, and the thickness of the vertical plate is mm and mm, which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm, which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm, which is suitable for the thermal insulation conditions above ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate including standard plate vertical plate width wa = mm, heaven and earth plate width WB = mm, vertical angle plate W = mm, W = mm, W = mm and W = . The dimensions of non-standard plates are different from those of Wa, WB and W.Heat pump, hot water, refrigeration and other fields. Supporting downstream products include: household air conditioner, multi on-line, modular machine, small water ground source heat pump, etc. At present, a single scroll refrigeration unit can achieve ~ HP.The physical properties of polyurethane insulation board are relatively good, which can meet different needs.
