No, a DX coil is not another term for a TXV coil. A DX coil is a type of evaporator coil used in air conditioning systems, while a TXV coil is a type of expansion valve used in refrigeration and air conditioning systems. A DX coil (Direct eXpansion coil) is a heat exchanger that allows the refrigerant to absorb heat from the air passing over it. It's located in the indoor unit and is responsible for cooling the air inside the room. The refrigerant enters the coil as a high-pressure liquid and exits as a low-pressure vapor, absorbing heat from the air during the process.
On the other hand, a TXV coil (Thermostatic eXpansion Valve coil) is a metering device used to regulate the flow of refrigerant into the evaporator coil. It's located near the evaporator coil and controls the amount of refrigerant entering the coil, ensuring optimal cooling performance and preventing overfeeding.
