San-AntonioTheIf there is more air or refrigerant oil in the evaporator, 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.
Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO9002 quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.
Baishi.Scroll refrigeration unit: at present, scroll refrigeration unit is mainly in fully enclosed structure, which is mainly used in air conditioning (heat pump)
The construction structure of structural cold storage can be brick concrete structure or steel structure which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.
.Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every 1 ℃ increase in the evaporation temperature of the cold storage can save energy by 2 ~ 5. Therefore, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.
General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon)
The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following 6 points: a low-temperature hall, a closed platform, an electric sliding refrigerated door, an anti-collision flexible seal, and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.
It is built in the room. There shall be excellent drainage pipe standards around the cold storage, the soil temperature shall be low, there shall be interlayer under the cold storage and good natural ventilation shall be maintained. Maintaining dryness is very important for the cold storage. In addition, the phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the tap water pipeline shall be paved and the FRP cooling tower shall be built.
Building plan and other relevant data of cold storage construction project.
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.
superior quality.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.
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 280-330kg 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 0.5-0.6.
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,BaishiInstallation of fruit and vegetable fresh-keeping cold storage, and the obturator rate is more than 95%. It is a dense microporous foam material, which is more dense than the surface of the air,BaishiTemperature monitoring of medical cold storage, and is not easy to permeate. It is an hydrophobic material.
General quick-frozen warehouses are mostly cooled by refrigeration mechanisms, so as to absorb the heat in the warehouse, so as to achieve the purpose of cooling and reduction.
Supply chain quality management.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.
The high pressure gauge shall be installed at the opening of the liquid storage tank valve.
Cold storage is mainly used for
Baishi.In the process of realizing your dream, you must remove all the influences. It is very important to recognize that when these beautiful refrigerators are built in the villa room, the collection pit (pool) for flushing (thawing) and drainage should adopt the Countermeasures of avoiding freezing and cleaning and avoiding backflow of water.
Clean and professional cold storage installation, cold storage installation, cold storage construction,BaishiInstallation price of cold storage, 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.
Regular oil discharge, descaling and air discharge: when there is a 0.1mm thick oil film in the evaporator coil, 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
