1.structure principle
inner loop
hot (gaseous) refrigerant vapor flows from the upper portion into the heat exchanger coil the spray water and air outside the tube horizontal and reverse flow, passing the tube wall and transfer heat with refrigerant within tube. after condensation, liquid refrigerant by circulating pump system to heat source again.
outer loop
the spray water will be sent from lower tray to upper tray by water pump, the spray water get in touch with the condensing coil tube and dry cold air which enter from the upper and lower from the tube to heat transfer. by evaporating small part of spray water, the heat will be taken, then the spray water after cooling through the packing, then falls into the water tray cycle again.
2.performance features
the way of air intake
both cross flow and countercurrent for air and water contact, that ensure air inlet flow to maximum extent and cooling efficiency of the tower body.
heat-transfer performance
air inlet from the upper and lower of the cooler, flows by pipes and filling while generating a greater air flow area with small flow resistance and excellent heat exchanger performance.
scaling preventing
air skims over the surface of coils horizontally and spray water downward. water will not separated from coils caused by air flow so as to prevent forming scaling.
easy maintenance
large space facilitates maintenance.
3.optional components
materials
all of the steel plate and structural items, including the structural framework, venetian support, the lower sink, fan platform and supporting can be optional type 304 stainless steel. the outer plates of cooling tower with two-sides inlet is made of frp,which is designed specially for corrosive environments or longer service life requirement.
electric heater
circulating water and spray water can freeze during cold winter months,which can bring out the disruption of pipes.we recommend electric heater and automatic control equipment to prevent fracture accident.
closed throttle (pcd) shields
positive closing throttle and throttle drive coil air intake guard can enhance the protective performance of heat loss.
electronic water level control package
when the water level control is required more in accurate or durable, it is widely used instead of water supply valve, including inductive devices and slowly closed solenoid valve.
extending the lubricating oil pipe
taking the end of the lubricating pipe as the standard lubricating adapter, and it can be used in drive bearing lubrication. the lubricating adapter located near the maintenance room door.
tank cleaning piping
installed in water sink, it is used to remove the debris and bypassed connecting to the sand filtration equipment.
control device of bacteria, mucus and algae
precise dose and low concentrations of natural iodine is sprinklered into circulating water automatically to control bacteria, mucus and algae growth.
high temperature thermal sink
consider to use when the high fluid temperature entering the cooling tower. you can contact our company for specific requirements
stand-alone fan system
each fan can run individually with dedicated motor and drive unique design for cooler with multi-model fans.
shock skip switch
mechanical or electronic vibration functions can be equipped; can effectively prevent the equipment from breakdown due to excessive vibration of drive system.
external repair facilities
aluminum ladder, installation platforms, external door and motor platform are designed to facilitate the maintenance.
