Systems Extreme Environmental Test Laboratory (SEET)



Trane's Reliability Testing Facility
In the SEET lab, Trane technicians will put a heat pump system through 2,688 hours of continuous testing, watching for signs of weakness or unusual wear. Why do they only test heat pumps? Because if a Climatuff® compressor can withstand SEET as a heat pump, it will easily handle any stress it may encounter as an air conditioner. During the 16-week testing period, heat pump systems undergo two-week cycles of torture, eight consecutive times, allowing engineers to measure and manage a system's quality and performance. Only the strong survive.

Trane Climatuff® Dual Reciprocating Compressor



More very interesting information from Trane.

Dual Reciprocating Compressor Operation

5-ton model has a 2.5- and 5-ton compressors. It is like having two systems in one. The 2.5-ton is the 1st stage compressor and it operates at 50% capacity and runs independently. The 5-ton is the second stage compressor and it operates at 100% capacity and runs independently.

How reciprocating compression works.

On the downstroke of the piston, when pressure in the cylinder is less than suction pressure, the suction valve is pushed off its seat allowing refrigerant into the cylinder. The gas enters efficiently in a cylindrical pattern around the circumference of the valve.

On the upstoke, the suction valve closes preventing refrigerant from leaving the cylinder. When cylinder pressure exceeds discharge pressure, the large round discharge valve lifts completely off its seat allowing gas to efficiently exit the cylinder. If there is liquid present, flow dynamics resulting from tapered surfaces and valve proximity will allow the liquid to be purged from the cylinder without damaging the valves. Besides being gas flow efficient, Trane's valving is engineered to tolerate some liquid slugging.

TRANE ALUMATUFF™ all-aluminum Comfort™ coils



Here is some information from Trane.

Trane's all-aluminum evaporator coils (pictured on the left after 500 hours salt spray) are constructed with aluminum tubes, return beds, and tube sheets. They will resist corrosion attacks from all typical sources.

HEAT PUMP CONTACTOR






WHAT DOES THIS CONTACTOR DO?

The contactor's purpose is to send 230 Volts to the Air Conditioning Condenser or Heat Pump compressor, crankcase heater and out door fan motor.

24 Volts of power from your thermostat is applied to the (2) side terminals of the contactor (if it is a 24 volt system, see coil voltages below)(all residential systems use 24 volt coils) assuming your thermostat is calling for cooling in the case of an Air Conditioner. In the case of a Heat Pump 24 volt power is applied to these side terminals on Heat Or Cooling.

WHEN SHOULD THE CONTACTOR BE CHANGED?

Since the contactor is always arching from 240 volts being applied across the contacts, it doesn't take too many years before the contacts get burnt and pitted. This pitting doesn't allow a full 240 volts of power from getting to the compressor and fan motor. This is known as "Voltage Drop". This Voltage Drop results in HEAT which then leads to burnt wires and possibly burnt motors and compressors.

The other reason is because through the years of operation the plastic part that the contacts slide in, wear to the point that the contactor can stick closed which can lead to frozen evaporator coils and burnt out compressors. If you think your outdoor unit is still running even though the indoor fan has stopped, suspect a sticking contactor! Change it before you ruin a $1,000.00 or more expensive compressor!

When we are servicing your system and the service technician tells you the contactor is burnt or pitted or shows you a burnt or pitted contactor, have it changed out to keep from having future problems. Also, while we are there, it will save you another service call.

THERMOSTAT FAN CONTROL SETTING



The optimal setting on your thermostat for the air handling fan would be to set it on the "AUTO" position. If you hear your air handling fan running all the time, make sure you have set the fan on "AUTO" on your thermostat.

AUTO" on the fan switch on your thermostat is the normal switch position for the fan control. Setting the fan control to "AUTO" will allow the fan to turn on when the air conditioning system (or heating system) are ready to blow cool (or warm) air into the building, and to turn off automatically when cooling or heating are not needed.

"ON" or "MAN" on the fan switch: there are reasons to leave the fan in the ON position on a heating or cooling system, but we do not recommend that you do this without first asking for advice from your heating and service technician.

Upgrading? Look For These Top Air Conditioning Features

With the summer heat bearing down on Florida, you might be wondering how well your cooling system will hold up for the duration of the season. In fact, you may be looking at new systems right now.



If you’re thinking about shopping, or you’re actually taking the initial steps to replace your system, the first thing you’ll want to consider is the efficiency rating of each unit. An air conditioner’s cooling efficiency is measured in terms of its seasonal energy efficiency ratio. While many older units have SEER ratings as low as 6, all units manufactured today must have a SEER of at least 13. The higher the SEER, the more efficient the equipment. Also look for the Energy Star label.

You will also want to consider various energy efficiency and home comfort features. Among the features you should consider are:

A dual-stage compressor: A cooling system with a dual-stage compressor runs on high when it’s very hot and at a lower speed when the weather’s milder. On most days, it runs at low speed for a longer time. This means a more even temperature and better humidity control, as well as operation that’s quieter and more energy efficient.

Thermal expansion valve: This device controls the superheat in the compressor. Used in place of a capillary tube or other fixed orifice device, it helps to ensure that the evaporator coil operates at maximum efficiency, regardless of the outside temperature. It also helps to ensure compressor dependability.

A fan-only switch: You can use this for nighttime ventilation when the temperature’s moderate.

A filter light check: This will remind you that it’s time to change the filter.

Unfortunately, the best system in the world won’t give you the economy and comfort you want if it’s not sized and installed correctly. Make sure your contractor uses Manual J to size your system. One that’s too big will cycle on and off too frequently, failing to remove sufficient humidity from the air and detracting from your comfort. One that’s too small just won’t do the job.
