If there is more air or refrigerant oil in the evaporator,Long-BeachFruit cold storage and vegetable fresh storage, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.

Goods in and out frequently, throughput

Long-Beach.The ground should be flat and not uneven. If the ground is uneven, the ground of the warehouse must be leveled before the cold storage can be built and installed.

During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, which will seriously reduce the local thermal insulation performance of the storage body.

.There are many application scenarios of cold storage, which are different. For a long time it provides various cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, honest operation, and has offices all over the country for long-term cooperation. Different purposes,Long-BeachMedical cold storage,Long-BeachTea cold storage, functions and designs so what needs to be understood in cold storage design?

Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and in the production process of cold storage, there will be no condensation in the cold storage of the plant. Condensation inside the cold storage or inside the insulation layer is harmful. Irreversible damage or deformation occurs in the new external insulation, and the external surface temperature of the external wall changes sharply. For example, the insulation and sound insulation effects of polyurethane insulation board are relatively good, which can be used in many industries. As we all know, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good, the cold storage will consume more energy during operation, and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next, let's understand the physical properties of polyurethane insulation board.

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.

These measures have achieved quite good results. Compared with several cold storages at a customer in Jining, the cold storages using their white materials have significantly lower power consumption than those using other white materials.

According to the needs and uses of different engineering scenarios, the design and construction of cold storage are different. When designing cold storage according to actual needs, nine aspects generally need to be considered.

During operation, the water temperature will still drop, and the humidification amount will be reduced by 70% at 5 ℃.

Equipment maintenance.The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore, building structures are vulnerable to. Therefore especially in the process of periodic freezing and thawing cycle, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.

Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Fault phenomenon of cold storage: the dryer does not operate, the compressor line is disconnected, the fuse is blown, the thermal relay acts, the high-voltage switch acts, the compressor is locked, and the environment

Commissioning cold storage. After all parts of the cold storage are installed and connected, the cold storage can be started for cold storage commissioning. According to the needs of customers, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge, as well as some after-sales training.

Installation of refrigeration equipment. The refrigeration system of the cold storage includes evaporator and units outside the cold storage. All equipment shall be installed in accordance with the construction specifications, and corresponding protection measures shall be taken for the installed equipment.

Home page recommendation.Precautions for purchase and shipment when using the medical cold storage project the speed must be strictly guaranteed during the purchase and shipment of products. If the temperature of the medical cold storage is about degrees, the opening time must be strictly within 25 minutes. If the temperature of the medical cold storage is left and right degrees, the opening time can not be too high, strictly within minutes.

Maintenance space shall be reserved for the installation of the unit to facilitate the observation of the adjustment of instruments and valves.

Watertight polyurethane rigid foam has low water absorption, good permeability to water vapor, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.

Long-Beach.Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.

The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.

Clean and professional cold storage installation cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage have stable performance, safety, reliability and maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.
