Cooling Tower And Chiller Operation

Cooling Tower And Chiller Operation Control System.

As the premier manufacturer in the China Zhejiang AOSUA Refrigeration CoLtd designs and manufactures cooling tower and chiller operation control systemWe devoted ourselves to cooling tower air cooler and negative pressure ventilation industry many years.

Cooling Tower Tonnage Cooling towers are not the typical 12000 BTUHrton The amount of BTU it takes in one hour to form one ton of ice they are 15000 BTUHrtonThe added 3000 BTU is for removing the Chiller compressor heatSo when a tower manufacturer says the tower is rated at 3 tons they mean 3 X 15000 45000 BTUHrton.

Cooling towers can develop certain problems especially if you neglect to properly maintain and service themThen once the issues persist and develop the cooling tower will develop more severe problems that will greatly hamper its performance potentially leading to breakages and failuresThat’s why it’s important to know more about the issues and prevent them.

Dec 11 2019nbsp018332This course covers the fundamentals and practical applications for understanding of design and operation of the chiller and cooling towerThe comprehensive coverage of the basic theory system analysis optimization concept and calculation methods to make this the most complete course available today in achieving an economical system.

For seasonal shutdown heat trace the makeup line to prevent freezing and simply drain the tower.

Here’s how they differ Chillers Chillers directly remove heat from an HVAC system’s coolant and transfer the heat to the air around itCooling Towers Cooling towers remove heat from the water that an HVAC system’s condenser unit dischargesSome HVAC systems use chillers while others use cooling towers.

Oct 02 2016nbsp018332Consider the cooling tower on top of a typical office type buildingA centrifugal pump moves water known as condenser water between the chiller in the basement and the cooling tower on the roofThe chiller adds heat to the condenser water and the cooling tower cools it down by rejecting this into the atmosphere.

Operation of this fan system is based on an occupied schedule of 630 am to 600 pm Tuesday through Friday and a start time of 600 am on Mondays during the heating season as determined by current weather conditionsDuring cooling season a start time of 530 am Tuesday through Friday with a start time of 430 am on Mondays.

Sep 02 2003nbsp018332Wet the fills first by starting circulation pump of cooling water and then start fanSecondly you will come to any irregularities in water flow through cooling towerChilled water primary pump will take care of the higher pressure in the chiller if you start it firstTo reduce initial cooling down time even though it is marginalchilled.

The key to successful winter start up is to preheat the water in the basin before it is directed up and over the tower  A heat load must be applied to the tower with the hot return water bypassed directly back to the basin  Water may then be routed up over the tower when the basin water temperature reaches approximately 80°F  Fan speed and number of fans operating may then be used to regulate the basin water temperature  As an added step in maintaining heat in the basin all fans may be deactivated.

These are the basic principles of a cooling tower system and apply to almost every cooling tower in operationCooling towers keep a heat source cool by evaporating waterHeat is transferred to the tower water in a heat exchangerChiller Tonnage One ton of cooling is the amount of heat absorbed by one ton of ice melting in one day.


Unfortunately noticing the first signs of corrosion often means it’s too late to prevent more serious issuesWhen leaks start to appear it’s usually time to perform more extensive repairs on cooling towersFirst test the water in the system to make sure it has low amounts of potentially harmful chemical compoundsAlso hire professionals to perform regular maintenance.
