A/C ABC's - How Central A/C Systems Operate

Posted by Javier on May 9th, 2021

Can you think of life without a/c? Sweltering heat waves that can melt the rubber on your shoes, prepare an egg on the dashboard of your car, and make it almost difficult to have an excellent night's rest-- sounds unpleasant!

Let's face it, life without A/C would not be the same. Did you know, that prior to the 20th century, ice was in fact collected for refrigeration? It was cut into 1-ton blocks, provided throughout the country and utilized in 'ice-boxes' to keep food fresh. The good news is today, refrigeration has been drastically enhanced given that its introduction in 1834.

By understanding how your home's A/C system works, you'll be able to make it run much better and longer, and if it must break throughout the canine days of summer, more confident finding a replacement.

What is Central Air Conditioning?

Considering that the 1960s, central air systems have actually been the most typical style of cooling in America.

Best characterized by the condenser system outdoors and ducts carrying cool air throughout the house, a main air conditioning is sometimes described as a "split-system" because the indoor and outdoor parts are separated.

How It Works

Comparable to how a sponge absorbs water, main air conditioners soak up the heat from inside the house and eject it outside through a procedure called "the refrigeration cycle."

It's easy to understand how an ac system works as soon as you see how the parts operate together.

Parts of a Cooling System

Divide into two parts; a system will contain an outdoor condenser system (listed below) and a coil housed on top of the heater or inside air handler. The outside condenser, which does many of the work, operates in tandem with the air handler/furnace that disperses the conditioned air into spaces of your home.

The Refrigeration Cycle

The cooling procedure starts when the thermostat spots the interior temperature has risen above the setpoint. It indicates the control panel in the air handler and enters into action.

1) The internal blower attracts the hot, moist indoor air from the return ducts into the air handler/furnace cabinet to be conditioned.

2) Dirty air going into the cabinet first passes through an air filter that traps dirt and debris.

3) The clean air then travels through the evaporator coil. Using metal fins to increase its surface location, the evaporator coil extracts heat and wetness from the warm air as the air travels through it. The clean, cool air is distributed throughout the home.

4) A set of copper tubes consisting of refrigerant, called a Line Set, link the indoor coil with the outdoor condenser.

5) The condenser dissipates the heat trapped inside the line originating from the evaporator coil by biking it through its coils where a fan on top presses air to speed up the process. The refrigerant is then compressed and takes a trip back to the indoor evaporator coil, where the cooling procedure continues.

HEATING AND COOLING Cheat Sheet

It's a good concept to familiarize yourself with the technical language used by HEATING AND COOLING experts to comprehend your system when it furnace repair edmonton reviews concerns making repair work or buying a brand-new unit.

HVAC - Stands for heating, ventilation, and air conditioning. This acronym is utilized to categorize all devices utilized to regulate air temperature level, humidity, and air quality.

Split-System - In referral to parts of the system running both inside and outdoors. In a split system, the condensing unit is found outside.

BTU - British Thermal Units - a measurement of how much heat energy can be eliminated from the air in an hour.

Heap - A measurement that refers to the cooling capacity your unit can provide under normal conditions. 1 Lot amounts to around 12,000 BTU's. Loads are often utilized when sizing an unit for your house, which can be identified based upon the square footage required to be cooled or heated up.

Unrivaled Knowledge

Easily, the heating system, cooling, and electrical systems all work automatically, without us requiring to fumble around in the basement or worse, a hot attic. Till something goes wrong.

Learning about your a/c system may seem frustrating at first, however as soon as you have the essentials down, you'll be able to comprehend not only how your system works, however also figure out lingo to make purchasing a replacement simple.
