Making sure the TXV is metering the right amount of refrigerant into the evaporator and is not overfeeding the coil is one way technicians can help their customers’ refrigeration and air conditioning systems operate safely and more efficiently.

When adding refrigerant to a refrigeration system, there are several different methods a technician can use to determine the correct amount needed.

Is it time for our industry to consider using pascals for static pressure measurements? What would the transition from inches of water column to pascals look like and how hard would it be?

Condensing units that are exposed to low ambient conditions must have some sort of low ambient control installed on them.

There are varying types of symptoms that can occur when a refrigeration system has an overcharge of refrigerant.

In this article, we will look take a closer look at capillary tube systems, as well as how to properly clean them.

Most systems employing capillary tubes as metering devices do not require high-side receivers, which add to cost savings.

Decreased equipment requirements and the increased potential for lesser maintenance costs have contractors looking into hydronic heat metering.

Based on hygrometer technology, this product identifies deviations from ambient rh levels, which can cause static hazards at manufacturing sites and discomfort in homes and offices.

The TXV also simultaneously controls a set amount of evaporator superheat while, under these same conditions, assuming the range and capacity of the valve is not exceeded.
