HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, location, and distributi
Like any typical air conditioner, central air conditioning also uses refrigerant to remove heat from the indoor air. This heat is pulled outdoors & cool air is pushed in through the ducts. Utilizing modern HVAC technology, smart thermostats can be coupled with central air conditioners for a ...

Ductless mini-split systems are installed in individual rooms and are common fixtures in multifamily homes, office buildings and hotel rooms. Also known as mini-split systems, these electric units include an outdoor compressor and condenser, refrigerant, an indoor air-handling unit, a heat pump, ...
HVAC and Refrigeration:Gaskets are used in air conditioning systems, refrigerators, and heat exchangers to maintain proper insulation and prevent refrigerant leaks. Power Generation:Power plants, including nuclear, thermal, and hydroelectric facilities, use gaskets in steam turbines, valves, and generators...

Check refrigerant levels as low refrigerant levels can affect the cooling efficiency of the unit (if you notice a significant decrease in cooling performance or ice formation on the indoor unit, it may indicate a refrigerant leak.) Regularly inspect and clean the drain pan, drain lines, and dra...
In liquid cooling applications, water has an operating temperature range of 0℃ to 100℃ (32℉ to 212℉). Purified water has had chemicals and contaminants removed, but it may still contain minerals. Distilled water is a type of purified water, that has had both contaminants and minerals rem...
the ammonia refrigerant is condensed in one coil to release its heat, and then its pressure is released through an expansion mechanism to absorb heat. When the system absorbs heat from inside your home, it provides cooling; when it releases heat to the interior of your home, it provides heat...
This paper presents different trade-offs of using the permanent magnet synchronous motor (PMSM), induction motor (IM), switched reluctance motor (SRM), and PM assisted synchronous reluctance motor (SynRM) for designing a 60 Nm, 16500 rpm compressor motor to run in a hermetic refrigerant ...
