Ac testing methods -

The amount of load and the percentage of sensible to latent load heat to humidity can and will dramatically impact the target superheat requirements. The SDP2 communicates wirelessly with the SMAN to deliver the target superheat requirements.

saving you steps, time and providing increased accuracy. Due to high accuracy design capacitive humidity sensor coupled with a thermistor for high temperature accuracy you can be assured of levels of accuracy and performance never before possible in the field.

Previously, you would need expensive a lab-accurate or custom measurement solution. Charge the system using the superheat and or sub-cooling method, for detailed charging procedures go HERE.

It is first important to understand that rated capacity and efficiency SEER is only achieved and measured under a specific set of conditions.

Capacity can increase or decrease with factors like indoor load, outdoor air temperature, line set length and lift, and supply voltage. The changes are small, but they are cumulative, and almost always result in capacity losses.

Very few if any systems will ever test in at rated capacity under full load unless the charge and the airflow are correct, the line set meets design requirements and the system is well maintained.

Many times what we are looking for as much as the absolute output is the change in capacity that is achieved under similar load conditions. Typically this is considered a field capacity or field EER energy efficiency ratio but no less a valuable piece of information which shows the technician and the homeowner what they need to see which is the actual work that the air conditioning or heat pump system is doing.

If we consider the electrical consumption watts including both those from the condenser and the evaporator fan, we can then show the work and the efficiency or the change in efficiency at which it is done.

The reason we also want to consider the electrical energy is two fold. A system can and will increase in amp draw if it is moving more BTU's. Moving heat energy is the work that is being done. What is important to remember is the ratio of BTU's moved to that of the watts used is what will dramatically change.

A system operating under less than full load can still operate with full capacity but at an electrical consumption disadvantage. Consider something like a dirty condenser, the evaporator may still be operating at its full capacity and the system able to reject the heat at a higher then normal head pressure on an 80 deg F day, not exhibiting a loss of performance until the outdoor air temperature is closer to design.

Cleaning the condenser coil on that 80 deg F day may result in no increase and maybe even a slight decrease in capacity but, but a huge increase in EER as the ratio of power consumed due to the lower head pressure per BTU moved is significantly increased. A technician only looking at capacity and not efficiency may miss or even be perplexed at the outcome if only the capacity is considered.

Before you remove the Fieldpiece SDP2 probes from the duct, verify the TEET Target Evaporator Exit Temperature and or? T temperature drop across the coil across the evaporator are correct. The SDP2 will not only show you what they should be, it also calculates how far away from the target you are.

Verifying that these are in line assures you that the system measurements, specifically evaporator performance and airflow are optimal. The evaporator exit temperature and the temperature drop will vary with the ratio of sensible to latent load, and the Fieldpiece SDP2 will consider this and provide you far more accurate results then looking for about a 20 deg.

F drop. Evaporator temperature drop can vary from degrees F with ease, and the only way to know when it should be is a look up chart, manufacturer's table or to simply read it from your SDP2. Search X. Performance Testing Home Cooling Performance Testing.
