Introduction:
Economics is a growing science. There is difference
of opinion among economists about its definition which has a general
acceptance. For the sake of convenience the set of definitions given by various
economists are generally classified under three heads:
1- Economics
as a science of wealth
2- Economics
as a science of material welfare
3- Economics
as a science of scarcity and choice
Adam
Smith was the founder of Economics. He in his famous book,” As Enquiry into the
Nature and Causes of the Wealth of Nations,” Described Economics as a Science
of Wealth.
Dr.
Alfred Marshall gave economics a respectable place among social sciences. Dr.
Alfred Marshall defined Economics as a “Study of mankind in the ordinary
business of life, it examines that part of individual and social actions which
is closely connected with the attainment and with the use of material
requisites of well-being.”
Lionel
Robbins gave his own definition of Economics. According to him, the definition
of Economics given by him is superior to that the other because it does not
contain and reference of the term material or welfare. It applies as much to
the case of an isolated individual as to the complicated networking of society.
It raises the status of Economics to that of science. It makes Economics a positive
science which deals only with facts. It forbids the Economics to pass any value
judgment of what is good or bad, right or wrong, etc.
The Theory of Production
It
is the desire of every business firm that the factor of production is organized
in such a manner that a given output can be produced at the lowest minimum cost
in a specified period of time.
It
is not necessary for a firm to combine the inputs in fixed proportions to
achieve a particular level of output. A firm can use a set of alternative
inputs to produce the same level of output. It may use relatively larger amount
of labour with very little capital or relatively more of capital and less of
labour.
Market Models
For
understanding the operation of prices system, it is very essential that we
should first know the meaning of the word market and the basic market
structures or models. Prices, in a capitalistic economy, are determined under
various market situations. At the one end commodities are brought and sold in a
market where each seller finds many customers for his products and each
customer many sellers.
In
Economics, the term market refers to an area within which buyers and sellers
are in communication with one another and within which exchange take place face
to face between buyers and sellers and sometimes by telephone, telegraph cables
etc. in the first case the area of the market is very restricted one. But in
the latter, the market can be a worldwide. In the words of Lipsey,” A market is
an area over which buyers and sellers negotiate for the exchange of a
well-defined commodity.”
In today's world,
everything is changing at fast paces. The changes that happen are witnessed
everywhere. In technology everything is progressing rapidly, and commercial air
conditioning is no exception to this trend. The fast paces in this area are due
to the fact that modern economy and the continuously rising energy prices call
for better and more economical solutions. Manufacturers are constantly in
competition and striving to develop alternative technologies. With these
alternative technologies specialists can obtain higher energy efficiency. In
commercial conditions, energy efficiency is a prime factor for achieving
economical heating and cooling in commercial air conditioning.
In the competition
which is going on incessantly, innovations are always welcome. Innovations hold
the promise of breakthrough solutions. With them it becomes easier to achieve
more energy efficiency.
Energy efficient
technologies are in the spotlight for developers. Commercial customers are
always eager to welcome new and more energy efficient solutions and options.
The strife for economies involves paying greater attention to energy efficient
options.
Geothermal systems are
not new, they have been on the stage for decades. Nowadays more and more
attention is turned to them, and more manufacturers are willing to invest in
them. Commercial customers are also aware of them and are interested in their
wider promotion. The reason is that with geothermal systems the efficient
heating and cooling are easy to achieve. With the envisaged further increase in
energy costs, it is understandable why geothermal systems are envisaged to rise
in popularity, including with commercial customers.
It is interesting to
note that nowadays designers allot all their attention to the whole loop
process and to its installation in house. Thus geothermal systems are designed
and manufactured in the best way, to serve as environment friendly solutions
which not only take a lot of care of the environment but also led to the
achievement of massive savings.
Environment
friendliness is a prime concern in all areas of technology, especially when
devices and equipment are manufactured for commercial use. Not only the savings
thanks to energy efficiency make geothermal systems appropriate green
solutions. These systems are environment friendly because they do not harm the
environment. The investments made in these systems efficiently pay off quickly,
and the rewarding results inspire more and more commercial users to choose them
as the solution for air conditioning on commercial scales.
It is true that
initially there are investment needed, but the big picture which includes the
long term use shows there are a lot of benefits in terms of savings. Customers
should be taught about the approach to using geothermal systems, so that they
can realise the benefits they are going to get by adopting them. The energy
savings must be measured over the long period of time, so the economic benefits
can be realised when customers think in the long term perspective.
The world is changing, and new approaches and
solutions are mushrooming. In commercial air conditioning, the trends are the
same. With geothermal systems customers can get an auspicious solution to their
commercial needs for heating and cooling commercial premises and buildings.
