Air Conditioning, Refrigeration Technology, and Applied Physics?

Improving Air Conditioning and Refrigeration Performance Via Magnetic Cooling

In the Popular Mechanics article “A Brief History of Air Conditioning,” the author begins the timeline in 1758 with Benjamin Franklin and John Hadley (1). Franklin “I invented everything,” and Hadley, professor at Cambridge University, discovered the cooling powers of evaporation of volatile liquids. Alcohol and similar type liquids, when applied to an object, evaporate quicker than water. The process is actually capable of freezing water.

Now leap forward in time to 2014. to an applied physics letter printed in AIP Scitation. The abstract of the letter, “Anisotropy-enhanced Giant Reversible Rotating Magnetocaloric Effect in HoMn2O5 Single Crystals,” begins by presenting the foundation for applied magnetic and magnetocaloric properties. The authors, M. Balli, S. Jandl, P. Fournier, and M. M. Gospodinov discuss the power of applying rotation rather than in-and-out implementation to the single crystal HoMn2O5 contained by the cb plane in a stable magnetic field. The process proves capable of driving efficient rotary magnetic refrigerators.

Magnetic Cooling, A Novel Path To Improved Air Conditioning and Refrigeration

The advantages of rotary magnetic refrigeration technology include reduced energy demands, elimination of harmful cooling fluids, and a simpler way of doing things. The end result: An environmentally friendly cooling process that works better and easier than modern fluid-compression refrigeration methods. Described as the key to better “green” air conditioning and refrigeration technology by the Canadian-Bulgarian research team credited with development of the process, rotary magnetic technology revolves around solid magnetic substances defined by the team as magnetocaloric materials. The primary efficiency of the process lies in the ability to scale in direct proportion to the generated magnetocaloric effect.

According to “Magnetocaloric effect and magnetic cooling near a field-induced quantum-critical point (3)” released by NCBI resources, the magnetocaloric effect (MCE) is defined as a “temperature change in response to an adiabatic change of the magnetic field.” Past applications of magnetocaloric refrigeration have been focused on cryogenic temperatures. However, the new applications point clearly to extending the power of the process to meet the need for room air conditioning. Previously, paramagnetic salts were the choice materials applied to low-temperature refrigeration — including room temperature control. However, the efficiency of MCE, ease of operation, and adaptability of the process under applied microgravity conditions paramagnets now offer a reliable alternative to standard dilution refrigerators and space cooling technology.

How It Works, A Simple Example

Ferromagnetic materials, known for a tendency to heat up when magnetized and to cool down when the magnetic field is removed, is considered a magnetocaloric material. Magnetic fields cause ferromagnetic materials to achieve a higher state of order. However, even as order is achieved, the increase in the material’s temperature generates disorder within the atomic lattice. By contrast, removal of the magnetic influence results in a more ordered atomic lattice, which in turn causes a reduction in the material’s temperature. The essential power of magnetic refrigeration: It uses heat transfer via fluid to recapture the produced cooling energy.

It may not be in your home tomorrow, but air conditioning, refrigeration and applied physics is coming your way. The power of magnetic cooling technology and the eco-friendly solutions of a rotating magnetocaloric cooling system may well change the path of both modern domestic and modern industrial air conditioning and refrigeration function. Simple. Efficient. And compact Arizona home air conditioning. You got to like it.

Gilbert HVAC Can Be Easy With This Guide

Written by Rm Harrington on . Posted in AC Installation, Buying Tips.

Gilbert HVAC Easy Buying

Unlike Gilbert HVAC buyers, some families are fortunate enough to live in temperate climates where the weather is always perfect. For the rest of us, we need good HVAC systems that keep us cool in the summer and warm in the winter. For help finding such a system, read the following Gilbert HVAC “Make It Easy” article.

Referrals

Shared information makes a good buyer’s tool. Before hiring a contractor for your HVAC system installation, ask for referrals. Although many A/C contractors have deal, offer discount services, and seem to know what they are doing, you cannot simply take their word for it. Get the names and call past customers. Find out what made this particular air conditioning company right for them.

ENERGY STAR Ratings

Wise Gilbert HVAC buyers install A/C equipment that saves money. Go with ENERGY STAR rated products. They are effective, environmentally friendly and very energy efficient. Cooling your home, or heating it if you install a heat pump, consumes much energy. Installing ENERGY STAR equipment reflects in lower monthly utility bills. Permit your Gilbert A/C installation to help you recoup the costs.

Written Agreements

It’s a no-brainer. Get your agreement with the Gilbert HVAC contractor in writing. This may seem unnecessary, but anytime a contractor tends to skip over this step the charge to the customer ends up coming shockingly high. If you have the agreement in written format, the vendor cannot go back and change the information or the plans for the job without your consent. Likewise with the warranty. Get it in written form.

Word of Mouth Advertising

To find a “great” HVAC specialists, check with your family and neighbors. Their recommendations for a Gilbert A/C installation company reflect experience. Likely, you already know someone who just completed a ton of research on home heating and cooling equipment and installers. It’s the kind of power-knowledge that you just cannot buy. So ask around. Find an air conditioning specialist in your area. Word of mouth advertising provides you with an easy way to save hours on research, time, and money too.

Air Conditioning Maintenance

A/C maintenance begins with your HVAC filter system. Checking your filters on a routine schedule can make the difference between inexpensive repairs and more expensive ones down the line. Put it in your monthly schedule, and then follow through. Furthermore, make certain that you keep an on-hand supply of replacement filters.

Storage

If you are running a heat pump, this condition doesn’t apply. In fact, merely living in Gilbert AZ removes most need for A/C storage practices. However, assuming that you use an air conditioning condensing system and that you shut down the breakers during the winter, take time to cover your outdoor air conditioning unit – and use a tight cover. This will keep it free of snow, frost and debris so that you’ll have a working unit when the spring comes and you are ready to uncover it and use it again.

Shade

Whenever possible, try to shade the outside compressor unit. The air in shady places is typically five to six degrees cooler than the surrounding air. If effectively shaded during the summer months, your Gilbert HVAC air conditioning unit will be up to ten percent more efficient than an sun-blasted unit.

Control the Thermostat

If you are looking to save money during operation of your Gilbert HVAC system, consider turning down the air conditioning in the summer and turning the heat down in the winter. Putting on a sweater on a cold day can save you a ton of money on your utility bill – as can enjoying a cold drink instead of heavy air conditioning use.

Gilbert HVAC Necessity

If you lived in a place with perfectly lovely year-around weather, you would not need heating or cooling in your home. But in Gilbert, doing without air conditioning means sweating all summer long.

Air Conditioning and Heat Pump Thermostats and Advanced AC System Controls

Written by Rm Harrington on . Posted in Arizona Air Conditioning Installation, Thermostats and Controllers.

Thermostats: The Tools That Manage HVAC Performance

In basic definition, thermostats and advanaced A/C system controls in air conditioning and heat pump systems are on/off switches. The switch functions in relationship to a thermostat’s set point as compared to changes in the indoor air temperature of the associated structure. But there is so much more to HVAC performance than what meets the casual examination.

Herein, the Arizona-based HVAC installation and maintenance group at American Cooling and Heating presents a brief overview of air conditioning and heat pump thermostats & advanced A/C system controls.

Basic Thermostat and A/C System Control Processes

In 1883, Warren S. Johnson invented the first electric room thermostat. The Johnson Controls technology used mercury and electrodes inserted directly through the glass. The systems were accurate within one degree of temperature.

Skip ahead. In modern technology, most 2014 air conditioning and heat pump thermostats operate on low voltage control circuits that pull 24 volts AC from a control transformer installed within the home’s heating or cooling equipment. Low voltage control technology provides a safety advantage that enables the thermostat to operate multiple electromechanical contractors, relays and sequencers at inherently safe voltage. Modern systems also include an integrated “anticipation” function that activates the contacts in a manner that prevents room temperatures from overshooting the desired temperature settings. And all this excludes the growing range of features associated with modern programmable thermostats & controllers.

Pre-digital Heating and Air Conditioning Thermostats

In 1953, Honeywell introduced the T-86 “Round” thermostat technology (1). This bimetallic-spring regulated room thermostat still controls millions of home heating and cooling systems throughout the world.

Typically mounted on a central wall within the home, the traditional Honeywell thermostat uses a basic dial-type round-controller design that includes two temperature scales and two temperature pointers. The top scale and pointer provides the adjustable components of the system. The bottom scale shows the actual physical temperature in the chosen area of the home. Rotating the pointer in the top scale to the right increases the desired heating requirements. Rotating the pointer in the top scale to the left decreases the desired temperature setting.

In the early years, thermostats designed to control both cooling and heating included a manual setting switch at the base of the unit. This switch, also seen in rectangular units of the pre-digital era, can be moved from heat-to-off-to-cool or back again. The temperature sensor within the units compare the air temperature near the thermostat to the settings of the system and turn on or off the associated heating or cooling equipment as appropriate. The heat/cool/off control switch assures that only the selected equipment can activate at any one time.

Digital Era Thermostats and Controllers

By the year 2005, nearly 97% of U.S. households used installed heating systems (2). During the same time frame, only 75% of the U.S. households used air conditioning. But the world is changing and the changing climates associated with global warming continue to press upward the demand for installed home air conditioning. Modern programmable thermostat and controller technology bestows a dramatic increase in features and capabilities. From simple on/off heating and cooling to controlled ventilation systems and from manual settings to controllers that respond to electricity price signals the home air conditioning and heat pump management system engages in a whole new arena of thermal comfort and energy savings. And then along comes thermostats and advanced air conditioning controls that link directly into the home Internet networking system.
