What metering device is most common on apartment air conditioners?
Bulk
What type of refrigerant metering device is used on most refrigerators?
A curator
Why does my Air conditioner starts by blowing cold air then warm air?
Low on freon, a weak compressor, or a restriction in your metering device.
What metering device is the most efficient for heat pumps?
Thermostatic Expansion Valve (TXV, TEV). Any high efficient system requires one.
Function of expansion valve?
Metering device The metering device controls the flow of liquid refrigerant through the system. The liquid enters at a high-pressure, high-temperature, sub-cooled state and leaves as a low-pressure, low temperature, expanded liquid state. Accurator Piston and Thermostatic Expansion Valves are the most widely used metering devices. Accurator Pistons are widely used because of their low cost and flexibility. The piston can easily be changed to match the capacity of the condensing unit. The Thermostatic Expansion Valve (TXV) is the most efficient type of metering device. The TXV automatically adjusts the flow of the liquid refrigerant based on the superheat of the refrigerant leaving the evaporator coil. As the load on the evaporator increases, the TXV increases the flow of refrigerant. This maintains the proper superheat. The TXV is efficient throughout a variety of system operating conditions, while the accurator is efficient only under designed conditions.
Air conditioning system is exothermic or endothermic?
An air conditioner, as a system, is an exothermic device. The purpose of an air conditioner is to move thermal energy (heat) from one place to another (from inside the house to outside the house). A perfect air conditioner, that is, an air conditioner that requires no energy to move the heat (such as a heat sink) is thermally neutral - it is neither exothermic nor endothermic. . Most devices we consider air conditioners require motors to drive compressors and fans. These motors, and the mechanical devices they drive, give off heat, and it is this excess heat that tips the scale and makes the air conditioner an exothermic device. .

Should you replace the coils when getting a new AC unit?
If you are talking about the indoor evaporator coil being replaced when you replace the outdoor condensing unit than yes. Reason being the two are a matched pair. Most of the time the older indoor A coils are fit with an accurator or cap tubes as a metering device for the refirgerant. The newer condensing units are based on the A coil with a TXV metering device. In short a mismatched system will never perfom as it is intended. However many contractors still try to sell only condenser replacements.
What is the most popular conditioner?
Suave naturals is the best selling drugstore conditioner
