Cooling Towers & Evaporating Condensers
A cooling tower is a heat exchanger that contains water and is used to remove excess heat by some buildings as part of their air conditioning, ventilation and/or heating systems. Cooling towers are used to cool water by putting air and water into direct contact to extract waste heat into the atmosphere. When the water and air meet, a small amount of water is evaporated, creating a cooling action. The cooled water is then pumped back to the condenser or process equipment where it absorbs heat.
An evaporative condenser is a device which facilitates the condensation, or return to a liquid state, of a hot gas or vapor in a tube system using the evaporation of water flowing over the tubes. In simple terms, an evaporative condenser uses a system of tubes exposed to a constant flow of water to cool and condense a hot gas.
Importance of Cooling Tower Maintenance
A polluted cooling tower will lead to a reduced cooling capacity which negatively influences the reliability of the system and can create health risks. However, this can easily be avoided by performing regular preventive maintenance.
Tenant of a Building with a Cooling Tower or Evaporative Condenser
If you live in a building with a cooling tower or evaporative condenser, please ask your building management to register online. All you have to do is copy and paste the message below into an email to your building's management:Dear Building Management,
I have recently learned that the City is taking proactive measures to register buildings' cooling towers. For the health, safety, and peace of mind of all the tenants who live in your building and in our community, I'd like you to register our cooling tower and ensure that it is properly maintained.
It takes just a few minutes using this online form on the Department of Buildings website: Cooling Tower Registration.
