An evaporative cooler (also swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in …

Another cause of valve failure is a rub out on bulb tube and an external equalizer without a core depressor installed on a port that has a Schrader core in place. When a valve is overfeeding the first thing to check is bulb insulation, placement and strapping.

If the thermostatic expansion valve is adjusted to produce too little superheat, liquid refrigerant may pass from the evaporator into the suction line. This is evidenced by an abnormally cold suction line and possible liquid flood back to the compressor. On the other hand, too much superheat results in the feeding of too little refrigerant to the evaporator. This will cause a …
