HVAC Equipment

Commercial HVAC equipment encompasses a wide range of systems designed to meet the heating, cooling, ventilation, and energy management needs of commercial properties. At HHC Services we believe that understanding the different types of equipment and their functions is essential for designing efficient and effective HVAC systems for commercial buildings.

Commercial Air Conditioning Systems

Commercial air conditioning systems are designed to cool large spaces efficiently and maintain comfortable indoor temperatures, even in high-occupancy areas. They can handle varying cooling loads and are often integrated with building automation systems for centralized control and energy management.

  • Packaged Rooftop Units (RTUs):

    These units contain all components (compressor, condenser, evaporator, etc.) in a single cabinet installed on the roof or ground.

  • Split Systems:

    Consist of outdoor condensing units and indoor evaporator coils, connected by refrigerant lines.

  • Variable Refrigerant Flow (VRF) Systems:

    Use refrigerant flow control to provide zoned heating and cooling with high efficiency.

  • Chilled Water Systems:

    Circulate chilled water through pipes to cool air via air handlers or fan coil units.

Commercial Heating Systems

Commercial heating systems are essential for maintaining comfortable indoor temperatures during colder months. They come in various types to suit different building sizes, heating requirements, and energy sources.

  • Furnaces:

    Use gas, oil, or electricity to generate heat, which is distributed through ductwork to heat the building.

  • Boilers:

    Heat water or steam, which is then circulated through radiators, baseboard heaters, or hydronic systems.

  • Heat Pumps:

    Provide both heating and cooling by transferring heat between indoor and outdoor environments.

  • Geothermal Heat Pumps:

    Utilize the earth's constant temperature to heat or cool buildings efficiently.

Ventilation Systems

Ventilation systems ensure proper air circulation, remove contaminants, and maintain indoor air quality. They work in conjunction with heating and cooling systems to create a comfortable and healthy indoor environment.

  • Air Handlers:

    Distribute conditioned air throughout the building via ductwork.

  • Exhaust Fans:

    Remove stale air, odors, and pollutants from enclosed spaces.

  • Makeup Air Units:

    Introduce fresh outdoor air to replace exhausted air and maintain indoor air quality.

  • Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs):

    Exchange heat and moisture between incoming and outgoing air streams to improve energy efficiency.

Commercial Controls and Automation

Commercial controls and automation systems enhance HVAC efficiency, optimize energy usage, and enable proactive maintenance and troubleshooting. They offer centralized control, data analysis, and customization options to meet specific building requirements.

  • Building Automation Systems (BAS):

    Monitor and control HVAC, lighting, security, and other building systems from a centralized platform.

  • Thermostats and Sensors:

    Control temperature settings and gather data on indoor conditions for optimization.

  • Variable Frequency Drives (VFDs):

    Regulate motor speed in HVAC equipment for energy savings and performance control.

  • Smart HVAC Controls:

    Provide remote access, scheduling, and energy management features for HVAC systems.
