What is connected to the metering device in a split air conditioning system?

The correct answer highlights the role of the metering device within the split air conditioning system. The metering device is responsible for regulating the flow of refrigerant into the evaporator, which is crucial for the system's operation. In a split AC system, the compressor is responsible for raising the pressure and temperature of the refrigerant before it moves to the condenser. Following this, the refrigerant cools and changes states in the evaporator.

Connecting the metering device to both the evaporator and the condenser is essential for ensuring that the refrigerant is properly managed. The device controls how much refrigerant enters the evaporator, enabling it to absorb heat effectively from the indoor air.

On the contrary, while other components like the receiver and accumulator play critical roles in refrigerant management, they are not directly connected to the metering device in the same functional context. Thus, the connection of the compressor and condenser to the metering device is pivotal to the refrigeration cycle and the overall effectiveness of the air conditioning system’s performance.
