VRF AC, or Variable Refrigerant Flow air conditioning, is a highly efficient HVAC system that uses refrigerant to heat and cool multiple indoor units from a single outdoor unit. It works by precisely controlling the amount of refrigerant flowing to each indoor unit, allowing for individual zone control and simultaneous heating and cooling. This technology uses inverter-driven compressors to match the system's capacity to the exact needs of each zone, leading to significant energy savings and quieter operation compared to traditional systems.
A ductless split AC, also called a mini-split system, is a heating and cooling system that works without traditional ductwork. It consists of an outdoor unit that houses the compressor and an indoor unit (or multiple indoor units) that is mounted on a wall or ceiling. These two units are connected by refrigerant lines and wiring, making it an efficient way to heat or cool specific rooms or zones, especially in homes without existing ducts.
Commercial AC refers to powerful, large-scale air conditioning and ventilation systems designed for non-residential buildings like offices, malls, and hospitals. These systems are built to cool and regulate temperature, humidity, and air quality in large spaces and are more robust than residential units, with various types available to suit different commercial needs.
In HVAC, a chiller is a machine that cools a liquid, usually water, which is then pumped through a building to provide air conditioning. It is the central component of a large-scale air conditioning system, removing heat from the liquid using a refrigeration cycle and then dissipating that heat to the outside air.
In HVAC, a "cassette" is a type of split air conditioning unit with a compact indoor unit installed flush with a false ceiling, leaving only a sleek grille visible. This design distributes conditioned air in multiple directions for uniform cooling and is often used in commercial spaces like offices and large rooms, though it is also available for residential use. The outdoor unit containing the compressor is located outside, connected by refrigerant lines hidden above the ceiling.
