Cooling Tower Fan | Commercial HVAC

Cooling Tower FanThis is an HVAC chilled water system cooling tower fan for a large chilled water system. Four large cooling towers for two chiller plants in a data center. Data center cooling systems generally are redundant not only for emergency situations but also for maintenance. The cooling tower fan typically has vibration switches installed in the fan assembly to shut the fan off in the event of too much vibration. (more…)

Cooling Tower Evaporation Cools Water | HVAC Technical

Cooling Tower Evaporation Cools WaterCooling Tower Evaporation Cools Water | HVAC Technical - Cooling towers use the process of evaporation to cool or removes heat from the condenser water that was transferred to the water in the chiller condenser barrel. The heat is absorbed in the load in this case in a data center on a data center floor. The servers and electrical equipment produce a massive amount of sensible heat.

The heat is absorbed by computer room air conditioners or computer room air handlers. These systems, computer room air handlers, and air conditioners have chilled water coils. The chilled water originates at the chiller into the primary loop. The water circulates through the primary loop and makes its way into the secondary loops. (more…)

Semi-Hermetic HVAC Compressor Rebuild Shop

Semi-Hermetic HVAC Compressor Rebuild Shop

Semi-Hermetic HVAC Compressor Rebuild Shop - These old semi-hermetic HVAC compressors are destined for the rebuild shop where they will see new life one day in a chiller or DX air conditioning system. If a business loses a compressor for whatever reason (usual burnout) they have the option of ordering a new compressor from the factory or calling a rebuild shop to see if they have a rebuilt reciprocating compressor that will replace the old one, or rebuild the bad compressor. This leaves the business the option of finding the best value or cost for replacing the compressor. These are semi-hermetic reciprocating compressors and can be torn down and rebuilt completely nearly like new ones. (more…)

MagicAire Air Handler with Hot Water Coil

MagicAire Air Handler with Hot Water CoilThis MagicAire Air Handler serves as part of a large club and uses a DX (direct expansion) coil for cooling and a hot water coil in the air handler for heating. Many commercial air handlers are set up in this manner for heating and air conditioning. Hot water for the hot water coil is supplied from an oil boiler which supplies hot water to other air handling units in this building. In the center of the photo is the hot water coil and to the left, the line set which feeds the DX coil can be seen. (more…)

Air Conditioner Squirrel Cage Blower | HVAC Air Flow

Air Conditioner Squirrel Cage Blower | HVAC blower motors move the air through the system. The blower motor is sized based on the amount of air flow necessary for the system. This blower motor is the supply fan for the supply air in a large commercial York AHU. An AC and heating forced air system is sized based on load. The load factors include heat loss and heat gain, number of people in the building, types of rooms served, factoring in heat produced by equipment such as computers and other heat producing equipment.

Prevent Poor Ventilation in the Home | HVAC and Health

Prevent Poor Ventilation in the Home

Prevent Poor Ventilation in the Home - You already know that inadequate ventilation in the home can lead to mold, mildew, and poor indoor airflow. This, in turn, can trap pollutants indoors, leading to allergies and other, more serious health risks. So what can you do to prevent this? Fortunately, you have several options, including energy-efficient ones. Here are some of them. (more…)

Goodman Heat Pump Condenser Flood Protection

Goodman Heat Pump Condenser Flood Protection

Goodman Heat Pump Condenser Flood Protection – This heat pump condensing unit has been installed on the platform. The area where this air conditioning condenser is located is prone to flooding. The platform raises the heat pump condenser at least one foot above the floodplain.

This is usually required depending on the municipality or government agency in charge of mechanical and electrical inspections. If you live in a flood-prone area it is wise to protect the equipment from flood damage. It is possible for the air conditioner condenser unit to run after being flooded. However, the life expectancy is drastically reduced and you will definitely experience mechanical and electrical problems. (more…)
