Frosted Evaporator Coils Can Affect the Efficiency of an HVAC System

October 25, 2017

Having regular maintenance on your HVAC system can prevent frost from accumulating on the evaporator coils. As the weather becomes colder the frosted evaporator coils start restricting the airflow and can reduce the HVAC efficiency. This is a common problem faced by the building owners and managers. Frost is the root cause of many HVAC issues. When the temperature in the evaporator coil becomes lower than the dew point and dew collects on the surface of the coil, it does not pose a problem. But when the temperature reduces further and goes beyond the freezing point turning dew into frost it reduces the airflow and can cause a major HVAC problem. Types of Frost The initial layer of ice which forms on the evaporator coil is thin and is not harmful. In fact, it is conducive to the functioning of the HVAC. It increases the evaporator tube’s surface area. The subsequent layers of ice are more snow-like or crystalline depending on the temperature of the evaporator, humidity, and airflow. They are known as hoar frost or radiant frost. They reduce the heat-absorbing capacity of the evaporator. Indications of Diminished Airflow Low Levels of Head Pressure – The heat load is reduced...

Maintain Your Cooling Tower Efficiently to Save Money in the Long Run

September 27, 2017

Regular maintenance of the cooling tower will help in increasing the efficiency of the cooling tower and reducing overall costs.

The bigger fight however, is to try and keep the utility bills lower. One way to achieve this is by maintaining your cooling tower efficiently. What is a Cooling Tower? A cooling tower is a device that is used to remove excess heat that is generated when the HVAC functions to either heat or cool a building. Cooling towers remove the excess (or waste) heat by evaporating some amount of the water that circulates inside the system into the atmosphere. These are usually seen outside the building or adjacent to the building housing the HVAC system Two Types of Cooling Towers There are two types of cooling towers: Natural draft – A natural draft cooling tower cools by way of natural convection of the airflow. As the air inside the cooling tower becomes warm and moist, it rises to the top in the form of steam that evaporates, and the cooler air that...
