The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material, which has excellent thermal insulation performance, more important is the choice of refrigeration system. For example, at present, the refrigeration system of fluorine refrigerant is still the mainstream, but when selecting the type and power of cooling equipment, it is necessary to calculate the data for the installation of cold storage, and then make a high-quality choice.Cold storage construction: which one is suitable for you? Which one is suitable for you?Santa Maria Chi malvacan,The customer specifies the refrigeration and conversion conditions required by the customer, the temperature of refrigeration and refrigerant, and the provisions of the customer's application site and application installation level.Cold storage, compressor overload, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.El-Mahalla El-Kubra,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.The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.The selection of equipment for the construction of equipment cold storage is closely related to the size,Santa Maria Chi malvacanInstallation of small cold storage, type and budget of the cold storage.

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.The selection of refrigeration system is important to the quality of controlled atmosphere storage.Improper adjustment or blockage of throttle valve, 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 refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease, and the decline rate of warehouse temperature will also slow down.Service first,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, medical cold storage, advanced technology, strict testing,Santa Maria Chi malvacanInstallation of low temperature freezer, more affordable price and more preferential. Welcome to consult. Pay attention to its compactness and continuous uniformity.Application of parallel compressor in cold storage: the requirement of refrigeration capacity is large, and to refrigeration compressors under Malige need to be used on weekdays; Long term operation, large load peak valley difference and significant departmental load; Frozen and refrigerated objects are novel foods that are easy to decay and degenerate, and have strict requirements for temperature and humidity.The selection of equipment for the construction of equipment cold storage is closely related to the size, and is not prone to failure only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, convenient use and management and long service life.OK or not?Generally, in the actual operation of the refrigeration system,Santa Maria Chi malvacanMedical cold storage installation works, because the temperature conditions are constantly changing, only by relying on the careful operation of the cold storage management personnel and accurately adjusting the operation of the refrigeration equipment of the cold storage, can the refrigeration system always be in the ideal working state and achieve the effect of energy saving.After the fresh-keeping storehouse is built, it is also important to pay special attention to the maintenance of fresh-keeping storehouse equipment in the whole process of application. Here are some key maintenance matters.Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.Santa Maria Chi malvacan,Requirements for refrigeration equipment in quick freezing warehouse: the strict sealing of quick freezing warehouse is obviously different from that of ordinary quick freezing warehouse. Therefore, all through wall pipelines must be equipped with sleeves, the frost flushing water return pipeline must be equipped with U-shaped bend water seal, and the main frost flushing and return pipeline outside the warehouse shall be equipped with air filling port to prevent the gas in the warehouse from being pumped out of the warehouse by negative pressure. In addition, due to the good sealing of the quick freezing warehouse, the set fluctuation range of the warehouse temperature should not be too large to prevent excessive positive and negative pressure from damaging the warehouse body.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.Moreover, polyurethane does not produce harmful gas at high temperature.
