How
It Works |
|
| |
|
|
| |
The
P.C.I. Water-to-Air Reversing System |
|
| |
|
|
| |
The P.C.I.
Unit utilizes the same basic principle as any refrigeration appliance
you have in your home - refrigerator, freezer, air conditioner, etc.
It transfers heat from a low-temperature media to a high-temperature
media |
|
| |
|
|
| |
Refrigerant is
circulated throughout the sealed system where it is compressed into
a hot gas, condensed into a cool liquid, and evaporated into a cold
gas. |
|
| |
|
|
| |
In the same way
that a refrigerator removes heat from the food and air inside, and
rejects it to the surrounding air, the P.C.I. unit extracts heat
from a liquid source and rejects it to the air used to warm your home
in the winter. |
|
| |
|
|
| |
In the summer,
the cycle is automatically reversed. The P.C.I. unit removes heat
and moisture from the air inside your home or workplace and rejects
this heat into the water or liquid source |
|
| |
|
|
| |
Since the liquid
source or ground water temperature stays relatively constant compared
to the wide fluctuations of outdoor air temperatures from summer to
winter. It provides an ideal heat transfer medium. In the cooling
mode, the liquid or ground water not only removes heat from inside
the building, but also carries away heat generated by the compressor
motor. The compressor runs cooler, more efficiently, and lasts longer
than conventional air conditioners. |
