Interestingly enough a big AC may not be your ideal answer to the summer heat. It might, in fact, provide you less cooling than a smaller unit, since smaller units run longer than bigger ones which tend to click on and off. Running longer permits smaller units to maintain a regular room temperature, remove moisture from the room (thereby getting rid of humidity) and ultimately gives you greater comfort.

Even if you are selecting a machine for central air-conditioning; the size is of considerable importance. This sizing however needs to be done by a pro. When dealing with a central air-conditioning system for your home make sure that the fan shuts off along with the compressor, that is, do not make the central fan for circulate the cool air, use circulating fans for each room instead.

Following are a few cooling tips which will save your air conditioning systems from breaking out in a sweat;

(1) Use whole house fans. These help maintain a cool temperature by dragging cool air through the whole house and throwing out the hot air through the attic. Whole house fans work best during night time […]

This circular gives advice on the precautions to be taken against the toxic, fire and explosion hazards presented by refrigeration systems containing
ammonia. These are most likely to be found by LA enforcement officers at cold stores and food distribution warehouses.

It applies to the entire system, not simply the compressor house. It provides interim advice on matters of concern to enforcement officers pending revision of BS 4434:1980.

Appendix 1
Outlines the general principles of refrigeration.

Appendix 2
Gives information on the results of the program of special visits carried out in 1983 by Factory Inspectorate (F1) to examine present standards in the food industry and

Appendix 3
Gives detailed guidance on electrical standards.

Enforcement officers should not overemphasize the hazards of ammonia compared with other refrigerants.

HAZARDS

Toxicity

Ammonia is a chemically reactive gas that is very soluble in water and is much lighter than air (vapor density 0.59 of that of air). Cold vapor (e.g.
from leaks) may however be denser than air. Although there have been incidents of exposure to harmful concentrations of ammonia in the UK there have been few fatal accidents. Ammonia is characterized by a typical pungent odor and is detectable by most people at levels of about 50 ppm in the atmosphere.

My favorite alternative cooling device is a gin and tonic. It’s portable, easy to operate and provides instant on-demand refreshment. lol

Is there such a thing as a Tanqueray energy tax credit?

Although you can install solar panels, a wind turbine or micro-hydro to generate the electricity to run an air conditioner, the only true whole house alternative cooling method is a geothermal ground source pump.

The cost of this type of system can be recouped in as little as two years on a new house installation, but the initial capital outlay is more than most homeowners can afford.

Let’s say you re-mortgage your house for $20,000 and you have a choice between a new kitchen and a geothermal heat pump; how many new heat pumps have your neighbors been showing off lately?

Less expensive options to consider:

Weatherization
The only people who haven’t learned the value of caulking, weather stripping and insulating yet are living in caves or tents.

Fans
Ceiling, paddle, and portable fans produce air motion across your skin that increases evaporative cooling. A moderate breeze of one to two miles an hour can extend your comfort range by several degrees.

Whole House Fans and Evaporative (Swamp) Coolers
These devices can […]
