• Sprinkler $\rightarrow$ Fire protection system

Answer 1

The Correct Option is C

Concept: Air conditioning systems are mechanical systems used in buildings to control:
• Temperature,
• Humidity,
• Air circulation,
• Indoor air quality. Different types of air conditioning systems are selected based on building size, cooling load, and functional requirements.

Step 1: Analyze each system listed in the question.
• A. Split -- A commonly used air conditioning system consisting of indoor and outdoor units. \checkmark
• B. STP system -- Refers to Sewage Treatment Plant system, not an air conditioning system.
• C. Packaged system -- A centralized type of air conditioning system used in buildings. \checkmark
• D. Hydraulic system -- Related to fluid power transmission systems, not HVAC systems.
• E. Sprinkler system -- A firefighting system used for fire protection.

Step 2: Identify the correct combination.
The air conditioning systems are: \[ A \; \text{and} \; C \] Therefore, the correct answer is: \[ {A\; \text{and}\; C} \]
