hilled water air conditioners are cost-effective and use less refrigerant for the refrigeration cycle than traditional HVAC units. Because of the savings and risk reduction, A chilled water air conditioning unit has a few major components, including the chiller, cooling tower, air handling units or fan coil units, pumps, and a pipe network. The chiller system cools water, which is then pumped through a network of pipes to air handling units. Air handlers, or blowers, blow air over condenser coils containing the cold water, and the cooled air then moves throughout the building. Warm air then returns to the chiller to be cooled again and starting the process over.
A direct expansion or DX cooling system is a type of air-conditioning system that removes heat from a space through evaporation and condensation of a refrigerant.
Compared to chilled water and other types of cooling systems commonly deployed in data centers or other IT spaces, DX cooling offers more flexibility and can operate at lower costs if the number of heat exchanges is minimized. Chilled water systems may be built out in larger blocks than a DX system, reducing the flexibly to build as you go. In addition, DX cooling can eliminate the need to introduce water into IT spaces filled with sensitive equipment.
Central heating is a system that generates and distributes heat throughout a building. It does this by producing heat at one point and distributing it to the rest of the building through either air, steam, or water.
Common used heating systems:
- Wet system
Where a boiler heats water which is then pumped through a network of pipes that connect to radiators in the house. Each radiator has valves that control the rate at which water flows through them
- District heating system
A district heating system generates heat in a single centralized power source and distributes it to several buildings in a particular area through insulated pipes.
As long as enough controlled fresh outdoor air is coming in and stale indoor air is exhausted out, a high-quality indoor environment will be achieved, Ventilation is so vital for ensuring acceptable Indoor Air Quality .
Mechanical Ventilation Types:
- Exhaust
Exhaust ventilation systems work by depressurizing a structure. The system exhausts air from indoor area, thus causing a change in pressure that pulls in make-up from the outside through leaks in the building shell and intentional, passive vents.
- Supply
Supply ventilation systems use a fan to pressurize a structure, forcing outside air into the building while air leaks out of the building through holes in the shell, range fan ducts and intentional vents.
- Balanced and Energy Recovery
Balanced ventilation systems neither pressurize nor depressurize a structure. but they introduce and exhaust approximately equal quantities of fresh outside air and polluted inside air.
We can provide all ventilation solutions for all kinds of residential, commercial, facilities and industrial building
