Commercial Mobile Air Conditioning Units: Controls (Electric & Refrigerant)admin
Heating and mobile air conditioning units have control systems that control and manage HVAC equipment. Control systems have inputs and outputs – for example, temperature is the input, while the output responds to information by either turning on or shutting off the system. A thermostat is an example of an HVAC control system. Without a thermostat, you wouldn’t be able to manage the temperature of the space.
Why air conditioning controls and refrigerant controls are important
Controls are crucial for keeping systems stable. If an HVAC unit had no control system to maintain desirable outputs, temperatures could reach dangerous conditions. Every cooling or heating system has controls, whether it’s an open-loop (independent of the output) or a closed-loop (dependent on the output) system.
An everyday example of an open-loop system is a toaster. The toaster’s control system includes a timer and only stays hot for the set time. An example of a closed-loop system is an oven which only heats up to the desired temperature set. The thermostat provides information to the oven and eventually reaches a steady and stable output.
Electric and refrigerant controls
As the name suggests, electric control systems use electrical inputs to control electrical outputs. These systems typically have two controls: “on” or “off” and sometimes have visual displays to show the system’s status.
Examples of electric control systems include:
- Water harness
- Automatic temperature control panels
- CTC circuit boards that control the blower speed
Refrigerant controls optimize the temperature and pressures in a refrigeration system. Without refrigerant controls, the refrigeration system would reach extreme temperatures and use heavy energy consumption. An example of refrigerant controls is refrigerant hose fittings and accessories with universal O-ring and fastener kits.
Where to find electric and refrigerant controls in Calgary
At Polar Mobility, we provide the above electric and refrigerant controls for commercial mobile HVAC units. Your heavy-duty machines on an operating work site need controls to function. If your equipment is reaching extreme temperatures or is using a significant amount of energy, it could be due to a malfunctioning control system.
