ConcepcionSmalThe evaporator surface is too thick or too much dust and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.
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.
Tres-Rios.After the installation of the controlled atmosphere storage, the temperature is too low, perhaps because the unit is too large, which leads to the rapid decline of the air temperature in the controlled atmosphere storage. However, it can be found that the temperature of the goods is still at a high level, or perhaps because the thermal insulation effect of the controlled atmosphere storage is relatively poor after the installation of the controlled atmosphere storage, then the heat dissipation will be accelerated, we must pay attention to its thickness. Only the modified atmosphere storage board with the required thickness can have a certain thermal insulation effect.
At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.
.Simple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed large total heat conduction temperature difference and complex system software, so it can only be used in less places, such as brine ice making and cold storage with constant temperature requirements.
It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is 15-20 degrees. If our humidifier is connected with the warehouse there is no temperature compensation, even if
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
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.
The maintenance of electrical equipment in the wholesale of fresh-keeping warehouse equipment is actually operated by welders or staff who understand the knowledge of power consumption. The switching power supply must be disconnected during maintenance.
The overall construction achievements of the cold storage project have been put into use, and the service life can reach 10 years.
Where can I find it?.The average service life of rigid polyurethane insulation structure with stable quality, long service life and high comprehensive cost performance can reach more than 30 years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.
Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage,Tres-RiosInstallation of vegetable fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore, it is necessary to be careful to select extensional perlite as cold storage.
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,Tres-RiosFruit preservation technology, adjust the value of the cold storage, 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.
Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35 ~ 40kg / m3, the thermal conductivity is only 0.018 ~ 0.024w / (m.k), which is the lowest among all thermal insulation materials at present.
Honest service.Core tip: in the cold storage project, only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, and is not prone to failure, convenient use and management and long service life.
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.
During the cold storage commissioning,Tres-RiosFood cold storage installation manufacturer, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.
Tres-Rios.In order to maintain a constant low temperature in 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.
General quick-frozen warehouses are mostly cooled by refrigeration mechanisms, and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions, so as to achieve the purpose of cooling and reduction.
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.
