The statement is true because a thermal expansion valve (TXV) is designed to precisely regulate the flow of refrigerant into the evaporator coil based on the cooling demand. When the load on the system changes—due to variations in temperature, airflow, or the number of connected devices—the TXV responds by adjusting the flow of refrigerant accordingly. This adaptability helps maintain optimal evaporator performance and efficiency, ensuring that the system can effectively handle differing levels of heat absorption. The TXV utilizes a thermal sensing bulb and a spring-loaded mechanism, which work together to modulate the flow rate based on the superheat in the evaporator, thereby making real-time adjustments to meet the changing load requirements. This capability is essential for maintaining the system's overall efficiency and preventing issues such as inadequate cooling or compressor damage.
