The basic composition of Freezer Condenser

After the liquid refrigerant absorbs the heat of the object to be cooled in the evaporator, it vaporizes into low-temperature and low-pressure steam is sucked by the compressor, compressed into high-pressure and high-temperature steam, and then discharged into the Freezer Condenser. Heat is released, condensed into a high-pressure liquid, is throttled into low-pressure and low-temperature refrigerant by the throttle valve, and then enters the evaporator again to absorb heat and vaporize to achieve the purpose of circulating refrigeration. In this way, the refrigerant in the system completes a refrigeration cycle through the four basic processes of evaporation, compression, condensation, and throttling.

In the refrigeration system, the evaporator, condenser, compressor, and throttle valve are the four essential parts of the refrigeration system. Among them, the evaporator is the equipment that transports cold energy. The refrigerant absorbs the heat of the object to be cooled to achieve cooling. The compressor is the heart, it plays the role of inhaling, compressing, and transporting refrigerant vapor. The condenser is a device that emits heat and transfers the heat absorbed in the evaporator together with the heat converted by the compressor work to the cooling medium to take away. The throttle valve has the effect of throttling and reducing the pressure of the refrigerant, and at the same time controls and regulates the amount of refrigerant liquid flowing into the evaporator, and divides the system into two parts, a high-pressure side and a low-pressure side. In the actual refrigeration system, in addition to the above four major parts, there is often some auxiliary equipment, such as Cold Room Condenser, solenoid valve, distributor, dryer, collector, fusible plug, pressure controller, and other components. They are It is set up in order to improve the economic efficiency, reliability, and safety of operation.

Chinese name Coil-type evaporator heat transfer coefficient K≥3000W/㎡℃ Application range Industrial and civil features Compact structure, small volume, and less floor space
Coil type evaporator uses copper core coil to separate the various evaporator systems. Various shapes of evaporators can be arranged in a limited space, which maximizes the heat exchange area in a very small space. Application and cooling of liquids such as oil tanks and water tanks. Due to the spiral shape, the heat exchange area of ​​a single system can be more than 14 square meters, and the heat transfer coefficient can reach K≥3000W/㎡℃, and at the same time, due to the continuous scouring of the evaporating fluid, The tube can float freely, expand and contract freely, so it is not easy to scale. If a small amount of water (oil) scale accumulates during long-term use, the expansion of the tube will realize automatic descaling, so the long-term use of heat exchange capacity will decrease It is not too obvious, and the heat exchange effect is good.

Coil type evaporators can be widely used in industrial and civil applications, such as organic chemical synthesis temperature control, oil refining temperature control, high-end hotels, restaurants, office buildings, school scientific research buildings, outpatient wards, and other buildings in the heating, air conditioning, and hot water supply systems Evaporative heat exchange equipment is used in the boiler room, heat exchange station room, and air-conditioning machine room.
The characteristics of the coil evaporator adopt a new structure of floating coil tube bundle, which improves the heat transfer capacity, and at the same time, the automatic descaling ability is greatly improved; the tube bundle can be connected by flexible joints, which reduces welding points and is more convenient for maintenance; compact structure, small volume, and occupancy The land area is small.

The Evaporator Coils For Sale Manufacturer Introduces The Structure And Composition

The manufacturer of Evaporator Coils For Sale introduces the coil type evaporator, namely the evaporating coil, also known as the cooling coil or platoon, which is widely used in small cold storage. Direct evaporation coil.

It exchanges heat with the air outside the tube, and the air performs natural convection by the temperature difference. However, when some cold storage uses evaporative coils, in order to increase the intensity of convection heat transfer, the temperature of the cold storage is more uniform.

Circulating fans or hanging air coolers are used directly in the cold storage to increase the air convection in the storage. Commonly used evaporating coils are smooth tubes or finned tubes. Ammonia refrigeration devices use steel pipes to wind fins, and Freon refrigeration devices mostly use copper pipes to wind fins or sleeves. Evaporation coils are specific to cold storage

In this case, there are two types of installation: top coil and wall coil. Generally, wall coils are used in the cold room of cold storage. Except for a very small number of ammonia refrigeration devices that use vertical pipes, they all use simple structures and installation Horizontal serpentine wall coil for easy maintenance. In order to make the lubricating oil carried by the refrigerant in the coil return to the compressor smoothly, it is generally necessary to enter the liquid from the upper part of the coil and return the air from the lower part.
Sometimes in order to improve the cooling effect of the evaporator coil, a double-pass evaporator coil is used. The evaporating coils are all designed according to the specific requirements of the cold storage, but more symmetrical rectangular structures are made. Wall coil or the top coil is parallel to the wall or top surface, and a certain distance (about 100mm) is reserved. The distance (not less than 300mm), in order to facilitate the natural convection heat exchange of the air.

The Custom Evaporator Coils manufacturer reminds us that the wall coil is also related to the cold storage floor.

Condenser Manufacturer Introduces The Classification Of Condensers

The air-conditioning refrigeration system consists of a compressor, a condenser (including Custom Condenser Coils ), an expansion valve, and an evaporator. Its working process is as follows: the refrigerant boils at the pressure-temperature, which is lower than the temperature of the object or fluid to be cooled. The compressor continuously sucks the vapor generated in the evaporator, compresses it to the condensing pressure, and then sends it to the condenser, where it is pressure-cooled and condensed into a liquid under pressure, and the heat released during the cooling and condensation of the refrigerant is transferred to the cooling For the medium (usually air used in computer room air conditioning), the condensation temperature corresponding to the condensation pressure must be higher than the temperature of the cooling medium, and the condensed liquid enters the evaporator through the expansion valve or other throttling elements.　　

During the whole cycle, the compressor plays a role in compressing and transporting the refrigerant vapor and causing the low pressure in the evaporator and the high pressure in the condenser, which is the heart of the whole system; the throttle valve acts as a throttling reduction for the refrigerant. Pressure acts on and regulates the flow of refrigerant entering the evaporator; the evaporator is a device that outputs cold energy, and the refrigerant absorbs the heat of the object being cooled in the evaporator to achieve the purpose of producing cold energy; the condenser is a device that outputs heat, The heat absorbed from the evaporator and the heat converted from the work consumed by the compressor are taken away by the cooling medium in the condenser.　　

According to the different types of cooling media, condensers can be classified into four categories, and their functions are as follows

â‘´Water cooling type: In this type of condenser, the heat released by the refrigerant is taken away by the cooling water. The cooling water can be used once or recycled. Water-cooled condensers can be divided into vertical shell and tube type, horizontal shell and tube type and sleeve type according to their different structure types.

⑵ Air-cooled (also called air-cooled): In this type of condenser, the heat released by the refrigerant is taken away by the air. The air can be natural convection, or a fan can be used for the forced flow. This type of condenser is used in Freon refrigeration equipment in places where water supply is inconvenient or difficult.　　

(3) Water-air cooling type: In this type of condenser, the refrigerant is cooled by water and air at the same time, but it mainly relies on the evaporation of cooling water on the surface of the heat transfer tube to absorb a large amount of heat from the refrigerant side as water The latent heat of vaporization, the role of air is mainly to accelerate the evaporation of water and take away water vapor. Therefore, the water consumption of this type of condenser is very small, and it is the preferred type of condenser for areas with dry air, low water quality, low water temperature, and insufficient water volume. This type of condenser can be divided into two types: evaporative type and shower type.

⑷Evaporation-condensation type: In this type of condenser, the cold effect produced by the evaporation of the refrigerant in another refrigeration system is used to cool the refrigerant vapor on the other side of the heat transfer partition, and promote the latter to condense and liquefy. Such as the evaporator-condenser in the cascade refrigerator.　　

The Condenser Manufacturer reminds us that the condenser of the air conditioner plays a central role in the entire refrigeration process of the air conditioner. In the entire refrigeration system, the refrigerant in the condenser tube directly exchanges heat with the air outside the tube to achieve the effect of cooling air.
