Micrologic Trip Units

Summer is nearly here, and your home will soon be heating up. But just the thought of looking for a new air-conditioner is enough to make you break out in a sweat.

How do you know which one to buy, and how it will affect your energy bill? The key to comfort and savings is finding the unit that fits your space. One that is too powerful will work too quickly, shutting off before most of the humidity has been removed, leaving your place cool but clammy. And all that cycling on and off can stress the equipment and shorten its life span. Energy efficiency is another factor: The energy efficiency ratio EER is a measure of how well a cooling system will operate when the temperature outside is 95 degrees.

Look for an air-conditioner with an Energy Star label, indicating that it is more efficient than required by government standards. With all of that in mind, here are some guidelines to help you find the right air-conditioner for your home. More than 75 percent of households with a cooling system use central air, according to the latest data from the United States Energy Information Administration. But New York City is one of the big outliers. The reason: Its building stock is older than that of most major American cities, according to estimates by the Department of Buildings, with about three-quarters of the buildings constructed before — in other words, before central air-conditioning became popular.

Retrofitting older apartments with central air means installing a condenser outside the home, a fan-and-coil system inside and ducts to distribute the cooled air. Even if you are willing to give up a closet to install a central air system in your prewar apartment, your building may not allow you to put a condenser on the roof.

And retrofitting an apartment built without ductwork could be prohibitively expensive. Still, because the ducts and mechanical components are built in, effectively hidden within the walls, floors or attic, central air is the most discreet option.

Hire an installer who will work with you on a well-thought-out plan for where to put the ductwork, and be sure to insulate that ductwork. Also, budget for seasonal visits by a professional to change the filter, clean the coils and perform other maintenance to ensure that the system is working properly.

Bottom line: If you have space for the ductwork, central air is a quiet, convenient and design-friendly way to cool your home. Mounted on a wall and operated by remote control, these systems still require an outdoor compressor, but there is no bulky ductwork involved. Refrigerant is circulated through tubing that connects the indoor and outdoor units.

Though not as discreet as central air, ductless mini-split systems are highly efficient, as each unit can be controlled separately. These systems can also provide heating. As with central air, you will need a professional installer and should budget for an annual maintenance check.

To figure out what size you need, measure the room you want to cool and calculate the overall square footage. You can find the recommended cooling capacity measured in British thermal units, or BTUs, per hour for your room size at Energystar.

Be sure to take into account sun exposure and how the room is used. If the room is heavily shaded, for example, the Energy Star chart recommends reducing capacity by 10 percent.

If more than two people regularly occupy the room, add BTUs for each additional person. In the kitchen, increase capacity by 4, BTUs. It not only cooled as efficiently and effectively as other window units of similar size and price tested by The Sweethome, it was also quieter, with a lower volume and deeper pitch.

If you want to change the temperature without getting up from the couch, it allows you to do so using your smartphone or computer, or with your voice via Google or Amazon Echo.

Built-in air-conditioners, also known as through-wall units, are mounted in a metal sleeve that goes through an opening cut in the wall. While The Sweethome has not tested any wall units, Mr.

Portable air-conditioners are not only more expensive, less efficient and noisier than window units, but they sit entirely inside the home, taking up valuable floor space, and use unsightly venting tubes that look as if they belong on the back of a washing machine.

Consumer Reports found that these units delivered only about half the cooling capacity they claimed, with few lowering the temperature to even 80 degrees after minutes running. Still, if you live in a building that does not allow window units, this may be your only option, apart from a fan.

All Micrologic trip units provide impeccable, electronic circuit protection with adjustable protection settings for maximum system coordination and flexibility.

Electricity is measured in units of power called Watts, named to honor James Watt, the inventor of the steam engine. A Watt is the unit of electrical power equal to one ampere under the pressure of one volt. One Watt is a small amount of power.

Build effective unit tests

Unit tests are the fundamental tests in your app testing strategy. By creating and running unit tests against your code, you can easily verify that the logic of individual units is correct. Running unit tests after every build helps you to quickly catch and fix software regressions introduced by code changes to your app. A unit test generally exercises the functionality of the smallest possible unit of code which could be a method, class, or component in a repeatable way.

A measuring instrument is a device for measuring a physical quantity. In the physical sciences , quality assurance , and engineering , measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units , and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty. These instruments may range from simple objects such as rulers and stopwatches to electron microscopes and particle accelerators.

Fundamentals of Testing

In the process, you will learn - in the most direct and constructive way - how computers work, and how they are designed. Therefore, we assume no previous computer science or engineering knowledge, and all learners are welcome aboard. You will need no physical materials, since you will build the computer on your own PC, using a software-based hardware simulator, just like real computers are designed by computer engineers in the field. The hardware simulator, as well as other software tools, will be supplied freely after you enroll in the course. Course format: The course consists of six modules, each comprising a series of video lectures, and a project. You will need about hours to watch each module's lectures, and about hours to complete each one of the six projects. The course can be completed in six weeks, but you are welcome to take it at your own pace. Really good course.

HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, location, and distribution. Primary HVAC equipment includes heating equipment, ventilation equipment, and cooling or air-conditioning equipment. Central HVAC systems locate away from buildings in a central equipment room and deliver the conditioned air by a delivery ductwork system. Central HVAC systems contain all-air, air-water, all-water systems.
