Refrigeration Gases
Many air conditioning systems incorporate an HFC refrigerant as the standard. It is extremely importantfor the HVAC technician to understand the propertiesof these refrigerants.
How to Charge Various Refrigerant
R-22 straight (सिधा) charge in vapour state.
R410 – upside down (ऊलटा ) Charge in liquid because it is a mixture
R32 – Straight (सिधा)
R290- Upside down (ऊलटा )R600 – Straight (सिधा)
R407 -upside down (ऊलटा )R417 – Straight (सिधा)
R134a Uses
R-134a:R-134a, also known as norflurane or Freon 134a, is a hydrofluorocarbon (HFC) refrigerant commonly used in automobiles, refrigerators
How it’s born
British Thermal Unit. It has alreadybeen established that a thermometer measuresonly the intensity of heat and not the quantity.However, in working with heat it is oftennecessary to determine heat quantities. Obviously, some unit of heat measure is required
A/C Contractor
e; the force developed by the electromagnet holds the moving and fixed contacts together. When the contactor coil is de-energized, gravity or a spring returns the electromagnet core to its initial position and opens the contacts.
Smart HVAC system
Smart HVAC systems also learn user preferences over time, optimizing comfort while reducing energy consumption. Additionally, they can send maintenance alerts, ensuring system longevity. Ideal for both residential and commercial use, smart HVAC systems are a step forward in sustainable living and modern home automation.
HVAC Chiller Room
The HVAC chiller room is the central hub for cooling systems, housing essential equipment like chillers, air compressors, air dryers, and associated components. It ensures efficient cooling for large facilities by circulating chilled water through a network of pipes to maintain optimal indoor temperatures. Proper operation, maintenance, and troubleshooting of equipment such as 250-ton chillers and 1000 scfm air compressors are crucial for system reliability
Manifold gauge
The gauge manifold in figure is colour coded. Manufacturers often colour code the exterior of the gauge – low side blue and high side red. Low side hoses are colour coded blue and high side hoses
HFCs
Hydroflurocarbons (HFCs) include such refrigerants as R134a and R-23. They are different from chlorofluorocarbons they contain one or more hydrogen atoms and no chlorine atoms. HFCS are considered to have zero potential for ozone depletion
