Air Conditioning And Psychometric Charts

By on 01/30/2017 in Air Conditioning Information

Psychometric Charts are a valuable tool in selecting an air conditioning system “just right” for you.

 

When an air conditioning contractor wants specific, scientific data on the amount of latent heat a new air conditioner will be removing on a regular basis.  This information is a big piece of the puzzle in deciding not only the size of the air conditioner to be installed, but also, the number, layout, and sizes of the ducts and vents throughout the building.

 

Dry-bulb temperature is the temperature of the air as measured by a thermometer suspended in the air and not exposed to radiation and/or moisture.  Wet bulb temperature factors in the moisture in the air and correlates it with measureable levels of comfort.

 

The psychrometric chart is a handy tool that enables the reader to determine and calculate dry bulb, wet bulb, relative humidity, dew point temperature as well as other gas-vapor relationships with only limited information. This chart helps people, especially involved in heating, ventilating and air-conditioning systems, to determine human comfort levels in relationship to changes in temperature and humidity

DBT is the temperature that is usually thought of as air temperature, and it is the true thermodynamic temperature. It indicates the amount of heat in the air and is directly proportional to the mean kinetic energy of the air molecules.

Unlike wet bulb temperature, dry bulb temperature does not indicate the amount of moisture in the air. In construction, it is an important consideration when designing a building for a certain climate. It is generally considered one of “the most critical climate variables pertaining to human comfort as relates to energy efficiency in both residential and commercial properties. The psychometric chart is one of the tools contractors rely heavily upon to determine the amount of latent heat, and moisture, a system will need to keep up with to ensure an acceptable level of comfort once the air conditioner is installed.

A look back at some of the air conditioner repair challenges

we encountered in 2016

 

Another year of air conditioning repairs, in SW Florida, is in the books.  Time for a final look back at 2016 before we bring our full attention to bear on the year ahead.  2016 was a year where we saw many customers that have been with us for years, as well as the many new clients we took on over the 12 months too.

 

2016 was a particularly good year with regard to expanding our “commercial client” as we began doing maintenance, inspection, repairs, and replacement for businesses in several different industries in the Fort Myers/Estero/Naples/Cape Coral areas.

Right at the end of the year we decided we needed another truck and upgraded to a 2017 work truck.  We feel the layout and set up for the truck make it the best air conditioning work vehicle in town!  Everything is laid out to the best specifications we could come up with after 47 years in business!

 

We REALLY like it!

Why Do Air Conditioners Ice Up?

Why do air conditioners ice up?

Our well stocked trucks, and well trained air conditioning technicians are always on call when you need air conditioner serve, repairs, or maintenance.

Our well stocked trucks, and well trained air conditioning technicians are always on call when you need air conditioner service, repairs, or maintenance.

 

The two main causes of an air conditioner icing up are low levels of coolant, or insufficient air flow.  There are several reasons why these causes can occur, but, basically it usually boils down to the Joule Thomson Effect …

 

The Joule-Thomson Effect is a principle in thermodynamics wherein if all else is kept at a constant, that a gas, as it expands, will have lower pressure, and resultant from that drop in pressure the temperature of that gas will also decrease. Conversely, as a gas is compressed, its temperature will rise.

Simply put, if air molecules are bouncing around rapidly, then you would feel this air as warm. If the air molecules are moving around slower or at a slower speed, then you would feel this air as colder. The heat generated by any gas is in direct coorellation to the energy of the molecules it is made up of.

This is the most basic concept to understanding how your air conditioner works. Your system works by allowing your evaporator coil to expand refrigerant inside of it, causing the coil to cool rapidly. As this rapidly cooled coil comes into contact with the air being circulated through your home, the refrigerant absorbs the heat from that air at the same time the air is being cooled by the air conditioner coils.

So iced up even the pipes inside the air handler were frozen!

 

Typically air conditioners will “ice up” when there is a significant drop in pressure within the system, or when the air blowing across the coils is insufficient to exchange warmer air with the cool coils.

An air conditioner running this iced up has the potential to do serious harm to itself!

In this case the cause of the trouble was not low pressure, but rather, insufficient air flow due to an ac filter clogged with animal (cat)hair.  Everyone should change their ac filter once a month … your air conditioner will cool more efficiently and cost less to maintain the level of comfort you prefer.  Those who have multiple pets in their home should be doubly  devoted to keeping their ac filter clean, as animal hair and fur have the potential to block off air flow completely … causing serious damage to their air conditioning equipment.

Air Conditioner Start Capacitor Trouble

Air Conditioner Start Capacitor Trouble

Air Conditioner Start Capacitor Trouble

 

Failing capacitors are one of the common reasons for malfunctions in an AC. Thankfully, if you catch capacitor trouble in time, repair technicians can easily swap them out for new ones without any serious effect to the AC. However, if bad capacitors are ignored, you may end up with a non-functioning air conditioning system right when you need one the most.  One of the most essential components of an air conditioning system are the capacitors. A capacitor is used to store energy in an electrostatic field. Capacitors perform the task of maintaining an even flow of voltage to running motors, and providing a requisite initial  jolt to start the motor in the first place. For air conditioning purposes capacitors are connected to three main motors … the compressor motor, the blower motor, and the outdoor fan motor. Each of these has an individual capacitor, or set of capacitors, to start it (the start capacitor), and to keep it running (the run capacitor).

The most common problem that bad capacitors can cause is “hard starting.” This is when the compressor of an AC has difficulty starting up, stutters trying to turn on, and then shuts off a short while later. There are a number of different causes for hard starting, but a bad start capacitor is probably the most common, as well as being a relatively simple, and low cost repair. while not always easy to diagnose that a start capacitor is the problem, a trained, knowledgeable  technician will quickly pick up on any visible signs such as splitting, bulging, frayed or discolored wiring, or even leaking oil.  They will also run electrical tests for amperage and continuity to be certain the capacitor is the source of  the trouble.

 

Bad hard start capacitor

Before a capacitor fails, it often times will begin to make a clicking noise or intermittently, run for only short periods of time, or make a humming noise as the motors begin to turn. This is a good time to have a contractor check it out before the compressor or other components fail and need repair or replacement.

In nearly all cases of capacitor problems,  the capacitor will need to be replaced. To try and repair the capacitor itself wouldn’t be cost effective, and would leave the customer with an “iffy” component that may, or may not, last for any particular amount of time.  Air conditioner professionals, know how to …

 

assess the problem safely and correctly

secure/obtain the correct replacement part

remove the old capacitor safely

install new capacitor to optimal, recommended standards

 

Start Capacitor Explosion

Capacitors associated with air conditioners are, generally speaking, bigger capacitors designed to assist starting motors, and then keeping them running. There are several motors present in an conditioner and heater systems and they all require capacitors to get them started initially, and then to keep them performing in rhythmic syncopation as well.  A typical residential air conditioning unit employs a variety of capacitors to keep it’s component parts running efficiently and effectively.

Proper maintenance is your best defense against the onslaught of high summer utility bills.

Here in southern part of the U.S. the cost of running your air conditioner is a major part of your electric bill. With a little thought and planning it is possible to significantly reduce the workload of your a/c unit thus reducing the amount of electricity you use and extending the life of your air conditioner.

  • Make sure your a/c vents, both incoming and return, are not blocked by furniture or draperies.
  • Turn off any electric light bulbs when not in use. Light bulbs generate heat that must be removed by your a/c unit.
  • Change your a/c filter monthly!
  • Cook on your outside grill when possible or use a microwave oven. Cooking on a stove or conventional oven adds heat to the inside of your home.
  • On cooler days open your windows or rely on ceiling fans to keep your home comfortable.
