Central HVAC systems are the most common type found in many homes and commercial buildings. They provide both heating and cooling from a central location and distribute conditioned air throughout the building through a network of ducts. | Ductless mini-split systems are more flexible alternatives to central HVAC systems. They consist of one or more indoor air-handling units connected to an outdoor compressor unit. | Ventilation systems focus on supplying fresh air and exhausting stale air to maintain indoor air quality. They are often combined with heating and cooling systems. | Geothermal heat pumps use the consistent temperature of the ground or water as a heat source in the winter and a heat sink in the summer. | Radiant systems use heated or cooled surfaces (such as underfloor heating or wall panels) to directly transfer heat to or extract heat from the indoor environment. |
Components |
Furnace: Used for heating by burning fuel (natural gas, propane, oil) or using electric resistance coils. Air Conditioner or Heat Pump: Provides cooling during the warm months and heating during the cold months. Ductwork: A system of ducts that carry conditioned air to different rooms. Thermostat: Controls the temperature and operation of the system. |
Indoor Units: Mounted on walls or ceilings in individual rooms or zones. Outdoor Unit: Houses the compressor and condenser. Refrigerant Lines: Connect the indoor and outdoor units Remote Control or Thermostat: Used to control each indoor unit. |
Air Intake and Exhaust Fans: Bring in and expel outdoor and indoor air. Filters: Remove particulate matter and pollutants from incoming air. Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV): Recovers heat or energy from outgoing air to pre-condition incoming air. |
Ground Loop: Buried pipes or loops filled with a heat-transferring fluid. Heat Pump Unit: Indoor unit that exchanges heat with the ground loop. |
Pipes or electric elements embedded in floors, walls, or ceilings. |
Refrigeration Cycle
The Expansion Valve
The high-pressure liquid refrigerant passes through an expansion valve or an orifice.
As the refrigerant passes through this valve, it undergoes a sudden drop in pressure, causing it to expand and cool rapidly.
The refrigerant exits the expansion valve as a low-pressure, low-temperature mixture of liquid and vapor, ready to enter the evaporator coil and start the cycle a new.
Refrigeration
EVAPORATOR In the evaporator, the refrigerant changes its condition from liquid to gas (boils) and absorbs heat from its environment in the process.
The room -air, supported by a fan, is being forced over the evaporator. It consists of a Lamelle Exchange, which exhausts the heat.
Embedded in the lamella exchanger run copper-tubes, through which the refrigerant circulates.
The compressor compresses the refrigerant-gas to a higher pressure- and temperature level and pumps the created hot-gas to the "liquidator“ (heat-exchanger).
The created vacuum in this process extractes the refrigerant-gas from the evaporator.
This process ensures a continuos supply of the refrigerant-gas and keeps the "cycling-process“ running.
Refrigeration - The Compressor
The compressor compresses the refrigerant-gas to a higher pressure- and temperature level and pumps the created hot-gas to the "liquidator“ (heat-exchanger).
The created vacuum in this process extractes the refrigerant-gas from the evaporator.
This process ensures a continuos supply of the refrigerant-gas and keeps the "cycling-process“ running.
The Refrigeration Cycle
The hot refrigerant-gas releases its heat in the condenser via a lamella-heat-exchanger to the atmosphere (outside).
The released heat-energy consists of the absorbed heat-energy (in the evaporator) and the compression-energy from the compression process.
The "liquidation-process“ (condensation) is comparable to the evaporation-process, however the change of the condition of the refrigerant is reverse, i.e. from gas-form to liquid-form.
- Pressure-Line – carries compressed Refrigerant-gas from the compressor to the condensor (incl. liquid oil, temp.: 80-160°C)
- Condensation-Line – liquid refrigerant flows to the expansion valve.(Oil is absorbed)
- Injection-Line – transports a gas-/liquid mixture to the evaporator
- Suction-Line – connects the evaporator and the compressor (refrigerant gas)
