8 Connections of the
refrigerant circuits
the connection of refrigerant pipe has to be made by an
authorized and competent staff. The connection requires the use
of a tool for welding.
8.1 Installation requirements
• The connection tubes between the indoor and outdoor
unit have to respect the sizes mentioned below.
• Not to respect the indication mentioned can cause a
significant decrease of the machine performance and it can
lead to incorrect operation.
• When there is a difference in height of more than 4 meters
between indoor and outdoor units, it will be necessary to
provide some special siphon every 4 meters high on the
refrigerant flow piping to help the flow of the oil possibily
dispersed in the circuit.
• Estimated amount of additional refrigerant liquid R410A
Gas (mm) Liquid (mm) Amount of gr to add for each meter *
12 10 15,00 g/m
18 12 25,00 g/m
22 12 30,00 g/m
22 16 50,00 g/m
28 16 60,00 g/m
* sub-cooling must be in a range between 3°C and 4°C with heat pump in steady state.
Example: in the case of a line with pipes with a diameter of
12mm gas and a length of 16 linear meters and pipes with a
diameter of 10mm for the liquid of 16 linear meters, the amount
of refrigerant to be added will be:
16 + 16 = 32 total meters
32 meters x 15 g / m = 480 total grams
NOTE!
Tthe parameter equivalent lenght has to consider the curves too.
Each 90° curve in the circuit has to be counted as a 1 m straight
portion. Each 180° curve in the circuit has to be counted as a 2
m straight portion. Each oil trap in the circuit has to be counted
as a 4 m straight portion.
8.2 Preparing for installation and
installation of refrigerant pipes
The connections of refrigerant pipes have to be sealed to avoid
the spillage of the refrigerant and the consequent malfunction
of the heat pump. The connection pipes have to be isolated and
have diameters specified in the following chart.
