What is the difference between the ZS and ZSX wall units from Mitsubishi Heavy Industries?
When you are looking for an efficient solution for heating and cooling, the Mitsubishi Heavy Industries SRK-ZS and SRK-ZSX wall units offer excellent options. Both models are designed to increase efficiency and comfort in residential or commercial settings. Nevertheless, there are some important differences that we would like to highlight in this short article. Below is a sample comparison of the technical specifications for the SRK 20 ZS-WF and SRK 20 ZSX-WF models that sheds light on the differences in performance:
SRK 20 ZS-WF | SRK 20 ZSX-WF | |
Cooling capacity (kW) | 2.0 (0.9 – 2.9) | 2.0 (0.9 – 3.4) |
Heating capacity (kW) | 2.7 (0.9 – 4.3) | 2.7 (0.8 – 5.5) |
Noise level GEM JIS (cooling and heating) (dB) | 45/45 | 43/45 |
Pipe length max. (m) | 15 | 30 |
Temperature limit heating | Tot -15°C | Tot -20°C |
SCOP (average climate) | 4.6 | 5.2 |
Energy class | A++ | A+++ |
Advanced features and benefits:
The SRK-ZSX series is equipped with a number of advanced features such as an economic operating mode with a motion sensor that reduces energy consumption by adjusting the operation of the unit to the presence of people in the room. This makes the SRK-ZSX not only more energy efficient but also smarter in use.
In addition, the ZSX standard is not equipped with an SC-BIKN2-E board but a special space has been created to integrate this into the unit. With the standard models, this board does not fit in the unit and has to be placed separately, which is less aesthetically pleasing.
Performance in cold weather:
A remarkable feature of the SRK-ZSX series is the superior performance at lower temperatures. With an operational capacity of up to -20°C in heating mode compared to -15°C for the SRK-ZS, the ZSX series provides reliable heat even during harsh winters. This makes it an ideal choice for areas with colder climates.
Noise level and ease of installation:
Both units excel in quiet operation but the SRK-ZSX models have a lower average noise level both indoors and outdoors, contributing to a more comfortable environment.
Moreover, with longer pipe lengths possible up to 30 meters, the SRK-ZSX offers more flexibility in installation, ideal for complex or larger spaces.
Conclusion:
The Mitsubishi Heavy Industries SRK-ZSX models offer several advantages over the SRK-ZS series, particularly in efficiency, advanced options, and performance in cold conditions. These features make the SRK-ZSX series a more 'high-end' choice for those looking for a sustainable, energy-efficient, and powerful air conditioning solution.
