What Makes a Heat Pump Work


Heat pumps are an effective and efficient way to both heat up and cool down substances and spaces.Heat pumps use a fluid, called a refrigerant, that circulates within a tube to transmit heat from one location to another. A heat pump can be used to cool down a room by transferring heat from it to the outside. A heat pump can also be used to heat a room by transferring heat from outside in.

There are many types of heat pumps, and once you understand how they work, in general, it becomes possible to appreciate how each of the various types works in its specific set of conditions. Heat pumps rely on two physical properties of liquids, condensation and evaporation to accomplish the heat transfer. When a liquid evaporates to the gaseous state, it readily absorbs heat from the surroundings. On the contrary, when a gas condenses to become a liquid it gives up its heat to the environment.

Now consider how the heat pump warms a room. The pump first causes the internal fluid to evaporate, and then flow through a section of the circular tube located in a space meant to lose heat. The gaseous refrigerant readily absorbs heat from the surrounding environment and then continues to circulate in the tube. Next it passes to the compressor, which compresses the gas causing it to heat up greatly. Now the hot gas circulates to the condenser, which is located in the section of the circular tube located in the room to be heated. The gas is made to condense and in the process it gives up a lot of heat to the surrounding environment.

The same heat pump can also function in the reverse direction, and it can be made to cool the same room it previously warmed. In this mode, the evaporated liquid is first made to flow through the room being warmed. The gas readily absorbs heat from the air, lowering the temperature of the chamber. Next the heated gas flows through the compressor and then the condenser, which is located outside. The gas changes to the liquid state and gives up its heat to the outside.

The refrigerant in the gaseous state can so readily absorb warmth that it can even take heat from air that is cooled to 0 degrees Celsius. Consequently heat pumps can actually warm homes even in winter weather. Of course, as the outside temperature drops, the efficiency of the pump drops. However, newer pumps can continue to work with 60% efficiency, even at temperatures as low as -17 degrees Celsius.

The efficiency of a heat pump is measured in terms of its Coefficient of Performance (COP). The COP is the ratio between the amount of energy used to make the pump work and the amount of heat change in the room being warmed or cooled. While an electrical heater normally has a COP of 1, heat pumps generally have COPs which can range as high as 7-8 in ideal conditions. This means that in most circumstances, heat pumps are more effective at heating and cooling than electrically powered heating and cooling units. This is why they are so often used today in the HVAC industry.

Modern Day Pet Care


Modern dog care facilities are sophisticated clinics which are equipped to treat your animal in style. A well equipped pet care facililty will include dog grooming, doogie daycare, dog boarding dog walking. Each of these chores is required ot be undertaken by properly trained staff members, and the whole pet care center needs to be supervised by a qualified and efficient manager.

Modern dog groomers could have trained as cosmetologists and or passed a six month course in a dog grooming academy. Stylish high quality pet spa centers will also provide pick up and drop off services for their canine clients.

Modern doggie daycare has come a long way from the crate and cage kennel. Serioius pet owners demand their pet to be boarded in a dog boarding facility offering an open air play area. To make this available, the kennels must also match up canine temperment. In a well run dog day care center, each dog will be observed before the start of the boarding to be sure they will reaact sociably with the other animals.

Dog boarding presents additional challenges. A large quality dog boarding center will have someone staying overnight with the pets. What if a fire broke out? With a night watchman on hand, pet owners can be assured that their dog will be well looked after round the clock.

To round out the list of services, a well equipped pet care facility will offer pet walking and pet sitting services and professional dog training. Also, when the owner comes to drop off his pet he will have the opportunity to select from a number of quality pet products.

Lest I forget, the modern dog care facility is seldom if ever called a kennel. In a large city, where there are many sophisticated pet lovers, it will more likely be called a pet club or pet salon. So when it comes to pet care, "It's a dog life" is not such a demeaning term anymore.

Pet Walking and Sitting


Dog walking and pet sitting is a service made available by many quality pet care facilities. The people who work in quality pet care facilities, such as the Bark Bark Club of Chicago, a fine Chicago Pet Care Facility, recognize the importance to pet owners of not leaving their pet alone. With this in mind, quality pet care facilities offer dog walking and pet sitting services so that the beloved pet
won't be left all by his lonesome when the owners are away. Dog sitting and pet sitting services give owners the option to leave their pets in the familiar home setting when they go away on vacation. Additionally, some owners would prefer putting their pets in crate free boarding when they are away on vacation, however, their pets fail the socialization requirements needed to be permitted into crate free boarding. So they can either put their animal in pet sitter.

Dog and pet walkers are bonded and insured individuals who can be trusted with animals and are sure to put the owner's mind at ease during the hours when he can't be at home with his canine companion.

All in all, pet sitting and pet walking are great services for people who are able to give their pets the care they deserve.

The Changing Landscape of Local Search

Imagine yourself magically transformed into a citizen of a small rural town in America, leisurely strolling through the village green, hub of the town's ordered domain. You gaze fondly at the weathered, tarnished obelisk rising from the village green. From the corner of your eye, you peer discreetly at the customers in Sam's Barbershop. Across the street, just as he has been for 14 years, Bob the town Baker is faithfully making tasty dainties for the local folks. Just 2 blocks down on the right is the trusty old hardware store, where you can now purchase everything from brackets to dead bolts, to any color of house paint you fancy. Main street is lined with tall elm trees; signs hanging from the facade of every shop, and inside every one of the brick and mortar stores, Mom and Pop, are hard at work from dawn to dusk providing needed business services for the townspeople. You can find everything you need on Main Street,

The dream of the originators of Google Local was to create an online shopping experience similar to Main Street, America. And thanks to colossal ingenuity of modern computers, it became possible for the search engines, and classified directories to provide web surfers, on request, an immediate list of stores and businesses providing the sought after product or service within the seeker's purlieu

This idyllic solution to Internet shopping was soon shattered, however, because the World Wide Web can only provide the illusion of shopping in a small town, and Google and other online Directories had to face problems posed by businesses vying for a share of the market. Why should a superior plumbing company, located in suburbia, be listed, on the search results, underneath the town plumber, when their plumbing company truck can be at the customer's house in 10 minutes. Why shouldn't a high quality Italian restaurant, located in the next district, be ranked above a take-out pizza joint when online users, willing to travel a few miles, are searching for gourmet Italian food?

Challenged by problems like these, the brilliant technicians at Google and other search engines added more factors into their "local search equations," which distorted and compressed the spatial and temporal realities of small town life. Factors, such as stability and reputation of the providing company, were added into the local search equation, and the imaginary small town became further distorted as closeness became defined in terms of the subjective needs of the consumer.

Big multi-city concerns began pounding the small town model. Companies, offering mortgages, loans, insurance, and national companies with local affiliates such as locksmiths, real estate agents and movers, began to fill up the local lists. The local search results, originally designed to inform shoppers of the nearest provider in their geographical neighborhood, were now filling with distant businesses submitted by entrepreneurs using tricks to get their clients top listing.

As the owner and Director of Express Submit, www.wexpresssubmit.biz , a company dedicated to rapid and effective Local List Submission, I won't deny that I fight hard to get each of my customers a top listing on the search engines. However, I can honestly say that my company has an ethic. Before I take on a job, I question each of my potential customers, to make sure they can provide their service in a timely fashion. If they live at a distance from the area they're serving, I want to make sure that their customers will not be penalized by travel costs. If my listing service will empower my clients to rank above other companies on the local list, I want to be sure, they will be providing an equivalent or superior service. I am happiest when I help a client with a quality product to get more customers.

The search engines have adjusted and in some cases facilitated the evolving character of Local Search, and at times, have bucked. But quaint as the idea may seem, how can anyone believe that our post-relativistic, futuristic world, can entirely be reduced to Main Street in a dawdling, Arcadian small American town.

Keyword Optimization for the Small Businessman

I am proud of my success in placing 100% of my clients on the first page of Google Local on important keyword searches, and I would like to share with you some of my secrets of good keyword list building.While there isn't space to detail all the techniques I use, and describe in my eBook, "Getting Your Business on Page 1 of Google Local in 4 Hours or Less," http://www.wexpresssubmit.biz/submissionebook.htm, I will describe some of the most important principles which every businessman should keep in mind when making his keyword list.
The number one secret, which I can't overly stress, is being diligent, and thoughtful, but not overly clever. Google and other major search engines are programmed by human beings, who want to help Internet searchers find what they're seeking. That's the goal of their complex algorithms. They seek out every clue that will help them determine what services businesses are offering, and conversely, what services businesses are not offering.

Don't try and trick the engine ranking process. Instead, before you even choose a single keyword, prioritize and determine the exact services your business excels at, and which ones you want to be found for. Then use appropriate keyword tools to find the search terms people will use to search for those most important services. Don't focus too much on hunting after "popular keyword choices," and "underused keywords," focus instead on selecting keywords that describe the services you're best at. For one thing, if you're like most savvy businessmen, you're using online classifieds on a daily and weekly basis to promote your business. You're filling your ads with descriptions of your company's most important services. If you have a web site, then those very keywords will hopefully be appearing on your web site as well. So when a search engine such as Google registers your local listing submission, and then compares it to information on the world web, it may find that the search terms you've submitted are associated with your company name in many other places. This resonance will give your business listing a significant boost in the rankings. And don't pick keywords that are too general. While it's still possible to get listed as handyman in many cities, it is just as important if not more valuable for a handyman who loves to do kitchen remodeling to list that service as well. More specific and multiple word keyword terms are definitely more and more popular as Internet users are becoming more and more experienced with online searches.
