5. TECHNICAL DESCRIPTION
OF THE PRODUCT
5.1. Heat pump unit. Working process.
The thermodynamic water heater is
designed to provide hot water by means
of a heat pump and a polyurethane
insulated water tank equipped with
an electric heater. The water in the
thermodynamic water heater is suitable
for drinking needs.
Scheme 3. Principle of operation
of the TDB-A model
1. Fresh air
2. Compressor
3. Evaporator
4. Thermoregulating valve
5. Water container
6. Capacitor
7. Hot water
8.Hot water /DHW/
9.Cold water
The operation of the heat pump is based
on the use of a certain gas (freon R134a)
which, in compression and subsequent
expansion, delivers heat to the water by
removing heat from the environment.
5.2. Water tank
The TDA water tank is a steel tank for do-
mestic hot water. The water purity and
protection of the metal from the corrosive
action of the water is ensured by a uni
-
form titanium enamel applied throughout
the entire inner surface. The water con
-
tainer has been designed for use with wa-
ter from the water supply network, with a
pressure up to 8 bar. The water container
is thermally insulated from the outside by
means of a 50 mm thick closed cellular
polyurethane structure.
5.3. Electric heating element
The appliance is equipped with two dry
electric heaters, each with a power of
1kW, providing additional thermal power.
5.4. Anti-freeze sensor
The controller measures the temperature
of the evaporator. If this temperature is
below -70C the controller disables the
heat pump unit and includes the heaters
for a period of 30 minutes.
5.5. Safety thermostat
The electric heaters are provided by a
safety thermostat with a limit of 90
0
C. This
means that if the temperature in the wa-
ter tank exceeds 95
0
С. the power supply
will be shut off and the heat pump unit
will stop working.
