Abstract
ABSTRACT:
The presence of HEAT PUMP systems has been with us for decades. The science of ENERGY
MANAGEMENT and today's environmental awareness prompted us to devise a unique HEAT
PUMP system especially tailored to the DOMESTIC HOT WATER market. "Simplicity" is the keynote feature of this system! It embodies a small compressor, a 40 gallon storage tank with wrap-around condenser, a unique evaporator and a method of using energy radiated by the compressor to give a secondary source of heat by the thermosyphon principle. This is accomplished by the use of a coil wrapped around the compressor, which transfers the heated water to the storage tank by thermosyphon.

Description
SPE(:IFICATION:
The primary objective of this innovative Vapour-Compression System (Heat Pump) is, to produce domestic hot water, The unit will absorb heat from basements, apartrnent, townhouses, condominiums and the outside air i~ necessary. If ~he evaporator is exposed to the outside weather, (sun, wind and rain) a sufficiently higher amount o~ energy will be ~enerated. This process is further enhanced by the addition of ~clip-on~' collector plates.
Energy absorbed by the evaporator from the ambient temperature or the environment, causes the refrigerant to change ~rom a liquid to a vapour. The absorption of energy is created by the change from a liquid to a vapour. The freon vapour is then compressed by the compressor which increàses the pressure and the corresponding temperature. The high pressura, high temperature vapour is then cooled in the condenser. This cooling releases the energy that had been absorbed by the freon in the evaporator. It is released in the form of heat to the water in the storage tank.
DISCLOSURE OF THE INVENTION:
Our HEAT PUMP system is exemplified in it's simplest form to produce domestic hot water; a task previously performed in a complicated manner (Fans, Motors, Pumps and complicated electrical controls).
A first embodiment of the invention is the applying of ENERGY MANAGEMENTtechniques. This discipline allows a 195 watt compressor with a C.O.P. of 2 to be adequate enough to raise the temperature of a 40 gallon galvanized water tank by a DELTA 'T' of 80 degrees Fahrenheit. It - also allows ~or the design of a simple efficient static EVAPORATOR, which eliminates the use of motor driven fans. This Energy Management technology was also used in the design of the COhlDENSER. By looping a length of copper refrigerator tubing around the storage tank, and brazing i~ to the outside wall for maximum heat transfer, both a water circu~ator and a double walled heat exchanger wcre eliminated.
A second embodiment of this invention is the extraction of the heat radiated from the compressor by usin~ a thermosyphon system that transfers the heat from the compressor to the storage water tank. A coil of copper tubing is wrapped around the compressor body to efficiently extract the energy generated during the operation of the compressor. One end of the tubing is connected to the bottom of the tank and the other to a higher inlet, thus creating a thermosyphon effect.

Fi~ure No.~ illustrates a conventional galvanized steel water storage tank (1).2~ r~s introduced by an inlet pipe (2) inserted in the top of the tank (1 ) and running to close proximity with the bottom. Hot water is discharged from the tank (1 ) through an outlet (3) at the top of the tank (1). A standard pressure temperature relief valve (4) is used with an over~low pipe, to prevent excessive pressure or temperature.
A coil type condenser (5) heats the metal skin of the storage tank (1), which in turn, transfers this energy to the water. Hot water produced this way at the bottom of the tank (1 ) is raised to the top by the ptocess of "natural convection".
The refrigerant flow control is achieved by using a capillary tube (6); it has two functions. Firstly, it allows the liquid refrigerant to enter the evaporator, and secondly it maintains the re~uired evaporating pressure in the evaporator. The method of opera~ion is explained as follows: The capillary tube (6) resists fluid flow, causing the pressure to reduce as the smaller liquid flow moves through the tube, until it starts to evaporate.
This change to vapour formation provides a sudden pressure and temperature drop, in approximately the last quarter of the length of the tube. The refrigerant is cooled to evaporator temperature and its pressure is reduced.
The capillary tube (6) is equipped with a filter drier at its inlet to remove any moisture or dirt from the refrigerant. The refrigerant is then compressed by the compressor which increases the pressure and the corresponding temperature. The high pressure, high temperature vapour is then cooled in the condenser (5). This cooling releases the energy that had been absorbed by the freon in the evaporator (9). It is released in the form of heat to the water in the s~crage tank (1 ) and the cycle starts again.
Also, water in the tank is heated by a second means via a coil (10) wrapped around the compressor (8) to extract heat radiated by the compressor (8). The upper outlet (11 ) of the coil is the high temperature end delivered to the mid inlet (12) of the tank, and the lower inlet (13) of the coil (1 ? is connected to the bottom inlet (14) of the tank (1).
As the water in the coil (10) heats up, it rises to the mid inlet (12) of the storaga ~ank (1 ) causing the cold water in the bottom of the tank (1 ) to flow back down to the lower inlet (13) of the coil (1 o)~
