HVAC industry

In the field of heating and ventilation, the application of spiral plate heat exchanger is generally mainly used in refrigeration and air conditioning system. The refrigerating liquid in the tube directly carries out forced heat exchange with the air outside the tube to achieve the effect of refrigerating air. The condenser is the high-pressure equipment installed between the compressor vent and the throttling device for the system when the external heat exchanger is refrigerating. It is the high-temperature and high-pressure gas discharged from the compressor of the air conditioner, which enters the condenser and dissipates heat through copper ring and aluminum foil. Axial cooling fans are installed in the air conditioner, and air cooling type is adopted. The manufacturer of spiral plate condenser, in the process of condensation, the pressure of refrigerant remains unchanged, the temperature decreases, and some gas is converted into liquid.

Field of application

Air conditioning and heat pump solutions

For air conditioners and heat pumps, energy efficiency and requirements for new refrigerants with low global warming potential and low global warming potential are crucial. Ukada is working closely with customers and universities to speed up development and is able to provide heat exchangers designed to meet new application regulations.

Product Display

Maintain optimal indoor climate

In the air conditioning cooler itself, various system manufacturers use the UKADA Brazed Plate or shell type heat exchanger as liquid evaporator and/or condenser. In larger buildings, other Alfa Laval heat exchangers need to be installed. In the heating or cooling system, gasket type plate heat exchanger with very close temperature is used to perform various intermediate tasks. The car roof is equipped with a gas-liquid cooler or condenser to eliminate excess heat.

Why did you choose ukada

Good product performance

The heat transfer efficiency of spiral plate heat exchanger is 1-3 times that of column tube heat exchanger, and there is no flow dead zone in single channel with equal cross section.

Effective recovery of low temperature heat energy

The fluid in the adjacent channel of spiral plate heat exchanger flows in a pure countercurrent mode, which can obtain the maximum logarithmic average temperature difference, which is conducive to the heat transfer of small temperature difference and make full use of low temperature heat energy.

Not easy to scale

The Tube on the shell adopts tangential structure with relatively low pressure loss. It has the ability of self-cleaning, the medium flows in a spiral type, its allowable flow rate is higher than that of other types of heat exchangers, and dirt is not easy to deposit.

Can be used in combination with multiple

When a single device cannot meet the use requirements, multiple devices can be used in combination, but the combination must comply with the following provisions: Parallel combination, series combination, equipment and channel spacing are the same. Hybrid combination: one channel is connected in parallel and one channel is connected in series.

Longevity of service

There is no welding seam inside and no fixed distance column, which avoids the internal leakage caused by the lack of stuffing during welding. It also avoids the compression deformation of the heat exchange plate caused by the falling of the fixed-distance column due to insufficient support density, thus reducing the service life! A large number of dense bubbling units in the new process improve the stress state of the Spiral Plate, greatly improve the strength of the spiral plate, and increase the service life by more than 30%.

High heat transfer efficiency

The fixed-distance column of the traditional process does not participate in heat exchange, and the heat exchange plate of the spiral plate heat exchanger without fixed-distance column (bubbling) of the new process participates in heat exchange as a whole. Every square meter per degree Celsius (kW/(m(· ℃)) two kinds of heat transfer media fully contact the heat transfer socket to change the flow state of the fluid, the flow direction and flow velocity of the medium change, strengthen the heat transfer effect, the heat transfer efficiency is improved by more than 30%.

Self-cleaning

The structure State of the non-fixed-distance column type (bubbling) spiral plate is more complicated than that of the ordinary spiral plate. The fluid flows in this structure, and there will be no fixed-distance column blocking the fiber. The corrosion resistance is more conducive to the cleaning of the equipment. No residual surface slag and oil slag, maintain the quality of oil products and prolong the service time of oil products. Therefore, the self-cleaning effect of the non-fixed distance column (bubbling) Spiral Plate will be stronger.

Compact structure

The spiral plate is a continuous single-channel structure with no dead angle and higher heat exchange effect. Under the same heat exchange area, the volume is greatly reduced, the bubbling units are dense, and the pressure bearing capacity is strong. The thickness and volume of the spiral heat exchange plate can be reduced, and the volume can be reduced by more than 25%.
