Chilled water Plant systems
The plant room comprises of all the important components of the chilled water air conditioning plant. These include the compressor, condenser, thermostatic expansion valve and the evaporator or the chiller. The water chilled in the chiller is pumped to various parts of the building that are to be air conditioned.
In the DX system the air used for cooling the room or space is directly passed over the cooling coil of the refrigeration plant.
Variable refrigerant flow (VRF), also known as variable refrigerant volume (VRV), is an HVAC technology invented by Daikin Industries, Ltd. in 1982. Like ductless minisplits, VRFs use refrigerant as the cooling and heating medium.
Primary / secondary pumping system
Constant speed pumps drive the flow through the primary (chiller or boiler) loop. A separate secondary pump delivers variable flow to the secondary loop and two-way valves are applied to control flow through each zone.
Thermal storage system
Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling astorage medium so that the stored energy can be used at a later time for heating and cooling applications  and power generation. TES systemsare used particularly in buildings and in industrial processes.
Hot water generator & Solar heater
Hot Water Generator, is the efficient and cost-effective way to generate hot waterinstantly. Instatherm is a packaged type, silent and instant hot water generator. Hot Water Generator can be pressurized or non-pressurized depending on the required temperature of water.
Ventilation, evaporative cooling systems
The ventilation aspect of your home's HVAC system is comprised of the flue and vent pipes. It might also involve a fresh air intake pipe or vent. The fresh air intake helps to bring the heated air to the correct temperature before it isdistributed throughout the house.
Clean room technology
Typically used in manufacturing or scientific research, a cleanroom is a controlled environment that has a low level of pollutants such as dust, airborne microbes, aerosol particles, and chemical vapors.
District Cooling System
District cooling system(DCS) distributes thermal energy in the form of chilled water from a central source to multiple buildings through a network of underground pipes for use in space cooling.
Heat recovery & cooling
Heat recovery ventilation works independently of your normal heating system. These flow past each other without mixing physically but the heat is drawn from the stale air to the cold air, which is then fed back down into the pipes and into the rooms. The stale air, minus its heat, is then expelled into the atmosphere.
