Component parts of the heat pump

Component parts of the heat pump

IVT Greenline HT Plus C

Three-way valve
The valve switches between heating
the heating water and hot water.
Venting nipple
The nipple is used to vent the
heating water in the cylinder.
Hot water heater
Double-shelled hot water cylinder
with inner section for hot water and
outer section heating water.
Electric cassette
The electric cassette is used
to provide extra output in cold
weather conditions, with large
water consumption and at hot
water peaks.
Reset button
Press in the button if the overheat
protector on the electric cassette
has tripped. The button is located
on the side.
Condenser
The condenser condenses the
vapour to fl uid again and transfers
the heat to the heating system.
Heat carrier pump
The pump ensures the heating
water circulates within the heating
system.
Compressor
The compressor increases the
pressure of the refrigerant.
The temperature of the vapour
increases from 0ºC to approxi-
mately +100ºC. The compressor is
insulated to reduce the noise level.
Flexible hoses
The hoses counteract vibrations in
the heat pump.
Sight glass
The sight glass is used to check the
amount of heat transfer fl uid in the
HTF circuit. Air bubbles must not
form in the sight glass when the heat
pump is running. However, there
might be bubbles when the heat
pump is started and stopped.
8
Electrical connections
Connections for the mains supply
as well as sensors.
Control panel
The control panel has a back-
ground lit menu display with four
rows of text information, three
buttons and a dial.
Electric box
The distribution box is enclosed.
It houses a reset function for the
motor cut-out as well as miniature
circuit breakers (MCB) for the
heat pump and electric cassette.
Heat transfer fl uid pump
The pump is insulated and
features an anti-corrosive fi nish.
It ensures the heat transfer fl uid
circulates from, e.g. the rock to
the heat pump.
Evaporator
The evaporator evaporates the
refrigerant to gas and transfers
heat from the heat transfer fl uid to
the refrigerant circuit.
Control unit
The control unit is enclosed. It
controls and monitors all heat
pump functions.
Expansion valve
Lowers the pressure of the refrig-
erant that enters the evaporator
and collects energy from, e.g. the
rock.
