The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done, otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?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,MonktonProfessional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, 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.Monkton,Another point is the ground maintenance measures in the wholesale of large fresh-keeping warehouses., Because the wholesale floor of large-scale prefabricated fresh-keeping warehouse is also a thermal insulation board, there will be a lot of ice on the ground in the process of use, so when cleaning these ice layers, you should pay attention not to beat them with a hammer or shovel, because it will damage the thermal insulation board on the ground. If the thermal insulation board is damaged it will affect the thermal insulation performance of the wholesale of fresh-keeping warehouse.Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, 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.Apia,Quick freezing storehouse is widely used. There are many kinds of temperature in quick freezing storehouse, and multi temperature or double temperature can be realized to meet the needs of different customers. Fault phenomena: unit current is large and voltage is too low; Loose wiring; The unit pressure exceeds the rated pressure; The oil separation core is blocked; Device failure; Host failure; Main motor fault; Fault phenomenon: the unit cannot be started and the fuse is broken; The temperature switch is broken; Loose wiring; Thermal relay of main motor acts; The thermal relay of cold storage fan motor acts; The transformer is broken; No power input (unit); Failure not eliminated (unit); The actuator is faulty.Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, and do a good job in rain proof, moisture-proof anti-collision, anti binding and other safety protection.Install the temporary lighting facilities in the warehouse install and arrange the construction electrical equipment, and do a good job in rain proof, moisture-proof, anti-collision, anti binding and other safety protection.

In fact, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first. Later, according to the height of the cold storage, make a hole in the middle of the insulation board, and tighten the angle iron parts until there is a hole on the insulation boardVacuum test: after the pressure test of the fresh-keeping storehouse system is qualified, the vacuum leakage test of the fresh-keeping storehouse system can be carried out. The purpose is to improve the air tightness under the vacuum condition of the fresh-keeping warehouse and prepare the conditions for the ammonia filling of the fresh-keeping warehouse system.Where do you need to build the refrigerator, storage capacity, ton, cubic meter, frame, box); What products are stored in the built cold storage? The actual storage temperature storage time and setting temperature can be indicated by specific regulations; If your cold storage becomes larger, you need to master your individual storage volume, the temperature of goods in and out of the warehouse,MonktonInstallation price of freezer, the frequency of opening and closing the door, etc. If this is clear, it is the selection of raw materials, refrigeration units, industrial cooling fans / pipe slots, thermal insulation materials, coolers, doors, temperatures and other refrigeration equipment.Inspection standard,Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, there should be interlayer under the cold storage the soil temperature should be low, and maintain good natural ventilation. Maintaining dryness is very important for the cold storage. In addition, before the construction of the cold storage, 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.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, the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, 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.

Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, and the quality of thermal insulation performance cannot be observed before it is really put into use. It is too late to observe the difference between power consumption. In this large number of experimental tests, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes, and its heat preservation performance is obviously better than that of ordinary foam with thick wall and big hole. The use of the tasteless amine catalyst can effectively adjust the balance between foaming and gel reaction, so that the interlayer skin of the sprayed coating is thinner, which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.Scheme customization,During production in the production workshop the unit weight of Pu warehouse board shall not be less than the unit weight required by the project,MonktonProfessional cold storage manufacturer, not less than & plusmn; kg/m.The inlet and outlet pipe diameters of the liquid storage tank shall be subject to the exhaust and outlet pipe diameters indicated on the unit sample.Energy saving and power saving: the design cost of quick freezing warehouse mentioned above is very low, but it has a great impact on the cost of quick freezing warehouse and later use cost. The electricity bill is often an important expenditure item in the later stage. The design scheme of the show can greatly reduce the power consumption of the quick freezing warehouse. The selection of the back sunny side of the quick freezing warehouse, the selection of the thickness of the thermal insulation board should be appropriate, the tightness of the quick freezing warehouse door, and the temperature difference between the adjacent cold storage rooms should not be too large are all issues that we need to consider. There are also some tips, such as the use of air curtain machine on the quick freezing warehouse door. We remind users to use parallel units in quick freezing warehouse as far as possible and start them reasonably.Monkton,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, the evaporation pressure and evaporation temperature also increase, 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 refrigeration capacity of the system will also decrease, and the decline rate of warehouse temperature will also slow down.Moreover, polyurethane does not produce harmful gas at high temperature.After the cold storage at the corner is installed, the next cold storage can be installed along the direction of the corner. Adopt the similar installation of Zhang cold storage to install the thermal insulation board of the storage. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, advanced technology, strict testing, more affordable price and more preferential. Welcome to consult. Pay attention to its compactness and continuous uniformity.
