How does solar air conditioning work?

In this episode of Sopohow, I’ll explain how our MicroCSP Technology works.
MicroCSP Technologies are scaled-down versions of traditional concentrating solar power technologies. In the case of Sopogy’s MicroCSP parabolic trough, we took the basic design from larger traditional technologies and reduced the solar collector to under half the original size. This new look at concentrating solar power technologies opened up new markets and gave Sopogy the ability to reduce the cost of the system, producing a modular and contractor-friendly approaching to concentrating solar power.
This technology works by taking a basic parabolic mirror In which all rays hitting the parabola meet at a central point of focus. In this shape the sun’s energy falling in parallel to the earth is reflected off our mirrors and through the receiver tube. In the receiver tube, we circulate the transfer fluids able to capture and retain the heat. We run the heat fluid through a series of collectors that increases the temperature of the fluid. Once the fluid reaches an ideal processing temperature, the fluid becomes thermal energy. Solar thermal process heat can be used for hundreds of different applications.
One common application is using solar thermal process heat to create electrical power. Here, we simply take our heat transfer fluid and pass it through a low temperature turbine to produce electricity. These turbines are often found in geothermal applications, but also just as easy to install next to solar thermal systems like Sopogy’s MicroCSP Technology. Our customers also use solar thermal process heat to create air conditioning or even directly for their industrial processes.
Choosing the right Air Conditioning SEER replacement unit
March 7, 2014
Customer: Can you tell me what SEER rating I should replace my AC with for my house to have the lowest power bill?
Tamara: We get this call once a week at our office. Unfortunately, there is no simple answer. If you need to replace your air conditioner and you want to upgrade, consider these facts: higher SEER units cost substantially more money, upwards of 50% more. There are better places to put your money to improve utility consumption. Also a 13 SEER air conditioner blows air at the same temperature as a 16 and a 20, so your home will not be colder or cool down faster.
The thermal rating of your house determines how often your AC will turn on, not the unit itself, so before you spend the money on a higher SEER AC to improve your utility consumption, consider other improvements first like resealing and double-insulating your ducts, low-e windows, solar screens, attic exhaust fans, radiant barrier for the roof and double insulation in the attic. Anyone of these will help your air conditioner kick on less often, the house to stay cooler longer and ultimately improve your utility consumption by far more than a high SEER rating.

Basic Air conditioning electrical circuits
March 6, 2014
There are 3 basic areas in the electrical circuitry: the high voltage source, the high voltage controls and motors and the low voltage controls. High voltage runs are the lines that run from your circuit breaker through service disconnects to your air handler and condenser. High voltage in your air handler powers the indoor fan, the heater and creates the low voltage power source through the transformer. High voltage in the condenser runs the outside fan and the freon compressor.
The low voltage circuit has 2 modes. Let’s look at the AC mode. In the AC mode, the thermostat sends the signal in 2 directions. The Y wire turns on the outside fan and compressor. The G wire turns on the indoor fan. In the heat mode, the thermostat also sends the signal in 2 directions. The G wire runs the indoor fan and the W wire turns on the heater or furnace part of the system.
Putting it all together gives the electrical circuitry for a basic air conditioning system.

Video – Air Conditioning Capacitor Check
March 6, 2014
What I want to share with you today is what we train our technicians to check when they’re doing our spring checkups. We’re going to do a little capacitor check. This could cause your compressor to go out. It could cause you to have high amp draw on the compressor. I believe it’s very important for every homeowner to have a service agreement or a club membership. That way they can have this checked out yearly. This is the most common part that we see that usually goes out in the middle of summer.
Let me show you how we check this when we come out and do a spring checkup. This is a 60 micro-farad capacitor. What we do is we take our meter and we check from common to hermetic. We’ll check the micro-farads and see if it is a 60 micro-farad. You can see this one is good.
Some of these will be running, it’ll start your unit and they can be 50 micro-farads. They can’t be less than three percent of what’s on the capacitor. All different units are different sizes, so we have to look at the tag and see what the micro-farads are. That’s how we check them. I would call in and definitely get your unit checked out today to make sure that you don’t have a capacitor going bad.
