What is an ECM Motor?

ECM stands for “electronically commutated motor” which means a motor that uses electronic controls to vary its speed (variable speed motor). The use of ECM motor technology helps raise efficiency of equipment by maintaining the relationship between speed, torque and airflow in HVAC systems, therefore reducing operating costs.

New ECM Options from ClimateMaster

ClimateMaster is excited to announce the most comprehensive offering of high-efficiency fan motor options in the commercial small packaged water source heat pump market. Constant torque, electronically commutated motors (ECM) are now standard options on commercial TC and TR unit sizes 006-060. Our new 3-tier motor offering provides the best opportunity to match the value to your specific job needs.

Units with EC motors have EER ratings up to 12% higher than units with standard PSC motors therefore conserving more energy and helping meet the latest building energy use requirements.

The constant torque ECM offers quiet and reliable service, with best-in-class energy efficiency. It can be a more economical EC fan motor option, when paired with our entry level CXM controls.

The Tranquility TY Series is one of the quietest two-stage units on the market and has one of the industry’s smallest footprints, making it suitable for tight spaces and for replacement/retrofit projects. Learn more about the TY Series here.

The Tranquility Compact (TC) Series is an extremely environmentally friendly single stage option that has one of the smallest cabinets in the industry and is designed to be backward compatible with older water-source heat pumps.

Prevent Condensation From Becoming A Design Flaw

Water condensation is easily the most common concern when discussing chilled beams and cooling panels. This concern comes from the personal experience many have had seeing water droplets form on the surface of piping such as a water coil.

When condensate forms it is too late to prevent the surface from becoming wet. The question, however, is how to prevent condensate from becoming a design flaw in the building.

The HVAC designer needs to verify that the ventilation system is capable of handling the latent load. Humidity loads that need to be addressed include:

  • Ventilation Load: Generally the largest moisture load.
  • Infiltration Load: Moisture that crosses the building shell.
  • Occupant Load: As people breathe and perspire, moisture is released into the space.
  • Other Loads: Fountains, doors and windows left open, wet clothing, etc.

To provide control of the air dew point and supply water temperature, several different control strategies are often used.

  • Monitor the local dew point temperature.
  • Monitor condensate on the chilled water supply (CHWS) piping.
  • Reset the CHWS temperature based on outdoor conditions.

Often, a combination of these control strategies is used. Other considerations are the type of fresh air systems (DOAS), system response time, building start up, night setback and recovery after high humidity levels in the interior space.
