  • Q1. What is sub cooling in air conditioning?
  • Ans. 

    Sub cooling in air conditioning is the process of cooling the refrigerant below its saturation temperature to improve system efficiency.

    • Sub cooling increases the efficiency of the air conditioning system by ensuring the refrigerant is in a liquid state before entering the expansion valve.

    • It helps in preventing flash evaporation of the refrigerant, which can lead to inefficiencies in the system.

    • Sub cooling is typically ...

  • Q2. How is ISEER rating calculated
  • Ans. 

    ISEER rating is calculated based on the weighted average of the cooling performance of an air conditioner under different conditions.

    • ISEER = (Weighted Cooling Capacity at 100% load x 0.4) + (Weighted Cooling Capacity at 75% load x 0.2) + (Weighted Cooling Capacity at 50% load x 0.4)

    • The higher the ISEER rating, the more energy efficient the air conditioner is.

    • ISEER rating helps consumers compare the energy efficiency of...

  • Q3. Draw the Refrigeration cycle
  • Ans. 

    The refrigeration cycle is a thermodynamic cycle used in refrigerators and air conditioning systems to transfer heat from a low temperature to a high temperature environment.

    • The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.

    • The refrigerant enters the compressor as a low-pressure gas and leaves as a high-pressure, high-temperature gas.

    • The high-pressure gas then flows into...

  • Q5. Explain 1 ton cooling concept
  • Ans. 

    1 ton cooling concept refers to the amount of heat required to melt one ton of ice in a 24-hour period.

    • 1 ton of cooling is equal to 12,000 BTUs per hour

    • It is commonly used in the HVAC industry to measure the cooling capacity of air conditioning systems

    • For example, a 2-ton air conditioner can remove 24,000 BTUs of heat per hour

  • Q6. Relation between current, voltage and power
  • Ans. 

    The relationship between current, voltage, and power is described by Ohm's Law, which states that current is directly proportional to voltage and inversely proportional to resistance.

    • Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.

    • Power (P) is calculated using the formula P = V * I, where P is power, V is voltage, and I is current.

    • In a circuit with a constant resistance, an increa...
