There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.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, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, and the decline rate of warehouse temperature will also slow down.Sequeira ,Refrigerated vehicle planning Kende refrigeration reminds enterprises with the construction needs of logistics refrigerated warehouse project to conduct in-depth communication with the project and refrigerated vehicle planning on warehouse location and actual use needs when determining the final installation construction mode, so as to ensure the smooth circulation of goods in logistics refrigerated warehouse.The importance of regular oil discharge, descaling and air discharge in the refrigeration system of the warehouse.Metapan,General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon)Artificial refrigeration keeps the room at a constant temperature. The walls, floors and flat roofs of large cold storages are laid with thermal insulation materials with a certain thickness 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.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, 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.

Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . Therefore, on the premise of meeting the refrigeration process of the product,Sequeira Fruit preservation, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.If the wholesale equipment of the fresh-keeping storehouse is started again after a long-term suspension, the speed should be reduced at the initial stage of the wholesale opening of the fresh-keeping storehouse. Don't start too fast. It's better to reduce the speed at about - degrees every day. When the temperature drops to degrees, it should be maintained for a period of time. Don't regulate it at will.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.Latest consultation, but it is necessary to grasp a certain limit and comprehensively consider the long-term energy consumption and initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at ~ kg / cubic meter. Therefore, it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton.Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.

The ultrasonic town is a patented technology with a shaped energy cover, which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?target,Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,Due to the slow cooling,Sequeira What is a cold storage, all equipment will consume electric energy during operation. If the cooling is slow, the equipment will stop and cannot consume electricity, so the electricity charge will not be consumed. As a high energy consuming equipment, the daily power consumption of cold storage is relatively large. If the refrigeration effect is not good, the annual use cost will directly double several times. Moreover, if the equipment operates for a long time, the service life will be reduced accordingly, which is something users don't want to see.Cold storage has good water tightness. Polyurethane rigid foam has low water absorption good permeability to water vapor, foam holes,Sequeira Professional installation manufacturer of cold storage, disconnected and closed porosity of more than %. It is a dense microporous foam material, which is more dense than air surface, and is not easy to permeate. It belongs to hydrophobic materials.Sequeira ,General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon)Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device, and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling, uniform temperature in the warehouse, and can bring harmful gases such as carbon oxide out of the warehouse during storage.Install the electric control system. The electric control system of the cold storage mainly includes electric controller electric door, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.

lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line
