AIR CONDITIONING SYSTEM.

LEARNING OBJECTIVES:. At the end of the lesson, the learners should be able to:.

ELICIT:. What is the use of refrigerator? What are the components of refrigeration cycle?.

ENGAGE:. Why so many people go to shopping malls during the summer ?.

What is air conditioning unit?. LG Refrigerator Back Grill, 320 V Ac, Rs 500 Emarc | ID: 24259499812.

It is a part of a central heating and cooling system, draws heat energy out of the house and transfers it to the outside air..

Air Conditioning System. an air conditioning system is an electrical device that is purposely installed for the removal of heat and moisture from the interior of an occupied space..

Components:. 1. Compressor – is a big electric pump that works with the condenser to turn the refrigerant back to liquid. It does this by pressurizing the refrigerant gas. 2. Condenser - It brings hot, condensed refrigerant gas back outside to vent the heat and turn the refrigerant back into a liquid form. ..

Components of Refrigeration Cycle. 3. Expansion valve – works with the evaporator, but is usually located in-between the evaporator and condenser. Its job is to regulate how much liquid refrigerant is moving into the evaporator, where it then changes into gas. ..

Components of Refrigeration Cycle. 4 . Evaporator - to receive liquid refrigerant and turn it into gas, which then cools and dehumidifies the air. The gas absorbs all of the heat from the air and takes it to the condenser. A refrigerant is chemical compound that is used as the heat carrier , which changes from gas to liquid and then back to gas in the refrigeration cycle..

Let’s watch this video clip!.

Air conditioning System.

Explore: Activity: It’s Cold Inside! Directions: Study the figure and the paragraph above. Read and understand the statement carefully. Write FACT if the statement is correct and BLUFF if the statement is incorrect..

Explain:. Describe the refrigeration cycle of an air conditioner. An air conditioning unit works by changing the pressure and state of the refrigerant to absorb or release heat. An air conditioning unit is a heat used for heating and cooling..

What is the difference between the refrigerator and an air conditioning unit?.

Elaborate:. How does an air conditioning unit work during summer and during cold days? During summer, it cools the inside of the house and heats the outside. During cold days, it takes the heat from the air outside to warm the inside..

Evaluate:. TRUE or FALSE: Directions: Read the statement carefully. Identify whether is TRUE or FALSE. Write TRUE if the statement is correct and FALSE if it is incorrect. ______1. The expansion valve regulates the volume of liquid refrigerant that is moving into the evaporator. ..

Question 2. _____2. In the evaporator coil, refrigerant absorbs all of the heat from the air inside turning into gas and takes it to the compressor..

Question 3 (TRUE or FALSE). _____3. The compressor is located in the hot side of the air conditioner with the condenser.

Question 4:. _____4. The condenser brings the hot, condensed refrigerant gas back outside to vent the heat and turn the refrigerant back into a liquid form..

Question 5:. _____5. Air conditioners function as dehumidifiers..

Extend:. What is heat engine? What are the types of heat engine?.
