Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.

What is a cooling tower?
What is a cooling tower?
A cooling tower is a distinctive heat exchanger structure that removes heat from water on a massive scale. During operation, hot water comes in contact with the cold air, which cools down the water through evaporative and heat transfer. Cooling towers are designed as heat transfer systems, but contact between cold air and hot water also cools the water through evaporation. A cooling tower aims to cool hot water used by industrial processes like machines and HVAC systems.

How does cooling tower work?
How does cooling tower work?
Industrial processes and Air conditioning equipment can generate tons of heated water that need immediate cooling. The hot water is pumped through the industrial cooling tower, where it's exposed to cold, dry air. The heat from the water escapes through evaporation. The cold water then returns to the air conditioning equipment or other processes to continue its cooling function. The cycle repeats over and over again. In the cooling tower, water is passed through nozzles which spray water into droplets enlarging the water's surface area and creating a better chance of cooling down. Moreover, a fan on top of the cooling tower brings cold air from the bottom as the water droplets flow in opposite directions.

What is it used for?
A cooling tower is a massive heat exchanger that helps to eliminate heat from commercial buildings, hospitals, schools, and industrial complexes. Cooling towers provide efficient and energy-saving operations for industrial processes that need cooling.
A cooling tower is used to remove heat from a building or facility by shooting water down the tower and exchanging heat with the structure's interior. Air enters the tower from all sides and flows through the falling water. Heat is transferred when the air travels through the water, and part of the water evaporates. This heat and evaporated water generate a thin cloud-like mist that flows out the top of the tower. At the bottom of the tower, the cooled water is collected and pumped back into the plant or building for reuse.

Types Of Cooling Towers
Types Of Cooling Towers
Cooling towers are important for industrial and cooling processes; otherwise, machines will break down, and safety can be compromised.
Crossflow
In crossflow cooling towers, water flows vertically while air flows horizontally inside the tower. In this setup, water doesn't pass through the distribution system; instead, it goes to hot water basins to be installed on top of the unit. Thus crossflow tower is gravity fed and is out of the way of the airstream coming in horizontally. Moreover, the hydrostatic head of the water is the driving force behind the spraying nozzles. This gravity-fed setup is easily accessible and can be cleaned when operating from the top of the tower.
Counterflow Cooling Towers
Counterflow towers are set to allow the air to flow vertically upwards against the flow of falling water droplets. Unlike in crossflow design, it's impossible to open sealed gravity basins crossflow designs. Also, crossflow uses pressurized pipe spray systems, making them inaccessible during operations. Moreover, the pipes and nozzles must be further apart to allow air to pass through easily without restrictions. The counterflow system also needs pumps to maintain pressure and also needs to be shut off to clean the nozzles. Consequently, with the design, someone has to claw inside the tight tower space to inspect or clean the nozzles.
