Application Example

Different owners may use separate outdoor units for their own operation costs and management.

It is more efficient to use separate outdoor units, rather than a combination of outdoor units to save installation cost.

Regulation EN 378To meet regulation EN378, the amount of refrigerant leakage should satisfy the following equation for human safety.

Total amount of refrigerant in the system

Volume of the room at which Indoor unit of the least capacity is installed <0.44

Project: VRF, capacity of 24HP (12HP+12HP)

Total quantity of R410A in the system = 24.8kg (oDU 12.8kg + IDU&pipes ~12kg)

Two separate 12HP outdoor units providing different solutions with two circuits.

20m2 20m2

24HP12HP 12HP

A combination of two 12HP outdoor units providing a solution with one circuit.

In the project, the smallest room/office is 20m², so 50m3.

The concentration in this room is: 24.8kg/50m3 = 0.50kg/m3

EN 378 not respected

Add ventilation system in all small rooms (20m²)(air flow 40m3/h each), with leakage detectors

Total quantity of R410A in one system (12HP) = 12.4 kg (oDU 6.4kg + IDU&pipes ~6kg)

The concentration in this room is: 12.4kg/50m3 = 0.25kg/m3

Refrigerant recovery and reuse

No refrigerant leakage design and production

The product monitors the operation status data in real time and decides the appropriate amount of refrigerant and displays it. It also automatically notifies the user of any small refrigerant leakage.

When performing maintenance on the product, the refrigerant is not discharged to the air, but saved by collecting it inside an outdoor unit, a refrigerant pipe, or an indoor unit. This increas-es environmental protection and reduces costs.
