COMMERCIAL HEATING AND COOLING
ENSURING COMFORT & RELIABILITY 24/7 IS WHAT WE DO
Ambrose Mechanical has the experience and training to service all types of commercial heating and cooling systems including steam and water boilers, chillers, cooling towers, water source heat pump systems and more. Call us today at 585-739-2770 and we can help you to have a better understanding of your system.
Commercial heating and cooling can include many types of systems including those with:
indoor furnaces, evaporator coils, outdoor condensing units, much like a residential system found in your home, central mechanical rooms with remote air handlers for air distribution, cooling coils, heating coils, remote condensers, cooling towers and controls.
Some of the more common types of equipment found in smaller commercial buildings would include split systems and what we refer to as RTU (packaged RoofTop Unit systems.) These types of systems are more commonly found in newer commercial buildings. Older commercial buildings often have much more expensive centralized systems that can include:
- air handlers
- cooling coils
- heating coils
- reheat coils
- variable air volume dampers
RTU’s, or package rooftop units, are usually capable of performing heating, cooling, air filtration and have economizer’s for ventilation air and free cooling when outdoor temperatures are below a certain point. Split systems can perform all these functions with part of the system inside and part of the system outside.
Commercial Heating Boilers
Heating boilers are more common in commercial buildings than residential buildings. Water boilers do not actually boil water. Steam boilers do boiler water and operate differently from water boilers.
Water boilers have circulators (pumps) that circulate the water being heated through the boiler and the system. Water boilers have other equipment to maintain proper system water pressure and controls to maintain the proper temperature.
Steam boilers do boil water into steam and are controlled with pressure controls that limit the pressure that is produced by the water expanding into steam. Steam boilers use water level controls to maintain the proper water level in the boiler. Steam boilers do not use circulators. The pressure of the steam in the boiler causes the steam to be distributed to the system.
Commercial Air Handlers
Air Handlers distribute air to conditioned spaces and have filter banks that clean particles from the air. They can also have UV lamps or Plasma units to purify the air and humidifiers to raise the humidity. Heating the air is accomplished with hot water, steam or electric coils. Cooling is accomplished with chilled water or refrigerant coils.
Commercial Ductless Systems
Ductless systems are usually heat pumps that heat and cool. These split systems use indoor consoles/air handlers that do not use ductwork and only condition the space they are located in.
Variable Refrigerant Volume (VRV) Systems
Variable Refrigerant Volume (VRV) systems, referred to by most manufacturers as Variable Refrigerant Flow (VRF) systems are like ductless systems but really are an alternative to more expensive hot water and chilled water systems. VRV systems do have indoor air handlers that are able to be ducted.
