Abstract
In many industries and organization, liquid chillers are used to store chemicals, milk, water etc. to have long life of that liquid for different applications at different time. Every cooler/chiller contain copper tubing in evaporator to supply refrigerant for chilling purpose & has composite wall type construction which reduces heat transfer rate. As a remedy of that SS strips can be welded on maybe by seam welding to produce numbers of path for the refrigerant on the inner tank. To reduce the heat loss whole tank will be insulated and that will be covered by the outer cover tank for ease of handling and appearance point of view.Current claim is bases on design done for 1000 litre tank capacity, which required to maintain liquid temperature at around ~8°C by refrigerant R-134a or R1234yf in less time and considered data can be vary as per requirements.
Description
Liquid Chiller / Cooler Tank
Description
SS strip can be weld on by continuous seam (Projection) welding to produce numbers of path for the refrigerant outer side of the inner tank. To reduce the heat loss whole tank will be insulated either by vacuum or puff insulation and that will be covered by the outer cover tank for ease of handling and appearance.
Here, motor is use to rotate blade which helps for equivalent cooling of liquid by circulation of liquid. Direction of refrigerant is considered from up to down in the opposite direction to the convective current of the liquid. This work is related with the selection of the refrigerant, design and optimization of the turns of the SS slot needed to produce required cooling effect.
Design is done for considering 1000 litre tank capacity having 1.2 m height, 1 m inner diameter and 0.5 mm thick, which is required to maintain liquid temperature at around ~12oC by refrigerant R-134a or R1234yf in less than 4 to 5 hours with considering water and milk as the required media to be chill inside the tank.
Here, tank is divided into small sections and design is done for required tubing in single section. Each division contain SS 304 strip shred which is to be weld by seam welding and converted into tubing form call slot. That number of turns is calculated and compared with the availability of space in each division by considering
different slot height for tubing.
Consideration of the tubing is slot width considered as 10mm for each calculation, the number of turns required for the lOOOlit tank capacity which is compared with the availability of the space in each division of the tank with considering 4mm to 5mm height occupied by the seam welding.
We may also vary required tank size to cool any kind of liquid which may result in low maintenance cost, 20% less manufacturing cost and 75% less power consumption by this design cooler tanks than existing liquid / water cooler.
Claims
CLAIM 1: Heat Transfer rate from the refrigerant to be increased by 8 to 9 time than conventional system of water coolers
CLAIM 2: Energy consumption/ Electricity consumption will reduce by 75%.
CLAIM 3: Manufacturing Cost can be reduced by 20%.
CLAIM 4: Low maintenance cost due to non corrosive material used SS304 than Copper.
