Component parts of the heat pump

Greenstore Combi

Three-way valve
The valve switches between
heating the heating water and
domestic hot water.
Venting nipple
The nipple is used to vent the
primary water in the hot water
cylinder.
Hot water cylinder
The cylinder is double-shelled and
holds approximately 185 litres of
domestic hot water and 40 litres of
primary water.
Electric heater
The electric heater 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 (not visable)
The condenser condenses the
refrigerant vapour to a liquid
again and transfers the heat to the
heating system.
Heat carrier pump
The pump ensures the primary
water circulates within the heating
system or domestic hot water
systems.
Flexible hoses
The hoses counteract vibra-
tions in the heat pump.
Compressor
The compressor increases the
pressure of the refrigerant.
The temperature of the vapour
increases from 0ºC up to approxi-
mately +130ºC. The compressor is
insulated to reduce the noise level.
Sight glass
Sight glass to check the level in
the refrigerant circuit. Gas bubbles
should not form continuously in the
sight glass when the heat pump is
running. However, there might be
bubbles for several minutes when the
heat pump is started. These will then
disappear

Component parts of the heat pump
Electrical connections
Connections for the mains supply
as well as sensors.
Control panel
The control panel has a back lit
menu display with four rows of
text information, three buttons and
a dial.
Distribution 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 heater.
Evaporator
The evaporator evaporates the
refrigerant to gas and transfers
heat from the heat transfer fl uid to
the refrigerant circuit.
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 the energy source to the heat
pump.
Control unit
The control unit is enclosed. It
controls and monitors all heat
pump functions.
Expansion valve
Lowers the pressure and regulates
the amount of refrigerant that
enters the evaporator.
Softstart
Reduces the compressors starting
current.
