The psychrometric process generally used in heat pump :
The psychrometric process generally used in heat pump :
Show Hint
In heating mode the indoor coil is hot and warms the air without adding moisture.
Updated On: Oct 20, 2026
- Heating and humidification
- Sensible heating
- Humidification
- Cooling and dehumidification
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
A heat pump is a refrigeration system that is used to heat a space. It takes heat from a cold source and delivers it to the room.
Step 2: Key Approach:
In winter the room air must be warmed. We find the process that only warms the air passing over the indoor coil.
Step 3: Detailed Explanation:
In heating mode, the indoor coil works as the condenser and is hot.
Room air blown across this dry coil gains heat.
No water is added to the air by the coil, so the moisture content stays constant.
Only the dry bulb temperature rises. This is sensible heating.
Step 4: Why the other options are wrong.
Heating and humidification needs a water spray or steam. A basic heat pump has none.
Humidification changes moisture, not temperature.
Cooling and dehumidification is the summer cooling mode of an air conditioner.
Final Answer:
The process generally used in a heat pump is sensible heating. This is option (B).
