What is a Heat Pump?
The
principle is very similar to the operation of a refrigerator, but only in reverse.
It utilizes
the energy latent in the ambient air, and can extract up to 80% of this free
energy from the air, to provide enough hot water for a detached house.
With a 303
litres cylinder, it delivers in excess of 500 litres of domestic hot water of up
to 40°C.
The beauty
about this technology is that the amount of electrical energy required to
operate the heat transfer process is far less than the energy used by a
conventional electric element.
For example
25°C air temperatures, 70% humidity and 45°C rise of water temperature, the fan
and compressor consume 1 kW of electricity to generate 4 kW of heat to the
water cylinder.
The energy
use is approximately 25% of conventional electric hot water cylinders, saving
you 75% off your electric bill, higher air temperatures mean more savings.
With the
predicted increase in energy costs and the cutting of greenhouse gas emissions,
the WWK 300 makes real sense for you and the environment.
In case a
greater volume of hot water is required occasionally, the WWK 300 can also be
equipped with a 1.5 kW electric booster heater.
This reduces
the heat-up time during times of demand.
How
a Heat Pump Works
The heat pump system contains a fan that forces air
through an Evaporator
(1). The evaporator contains very cold liquid
refrigerant. The heat in the air passes through this evaporator and is absorbed
by the refrigerant. The now warm gaseous refrigerant is then circulated in the
system via a Compressor
(2). As it goes through the compressor its pressure
rises and the temperature increases further. From here it travels to the
Condenser
(3). where the heat from what is now a super hot
refrigerant is transferred to the water supply tank. The cooled down
refrigerant then goes through an Expansion valve
(4), which reduces its pressure cooling further, and
the cycle starts again.
