Mitsubishi Heavy SRK25ZS-W/SRC25ZS-W2 split air conditioner for efficient cooling and heating
The Mitsubishi Heavy SRK25ZS-W/SRC25ZS-W2 split air conditioner is a mono-split air conditioning set for conditioning individual rooms. The set combines a wall-mounted indoor unit with a matching outdoor unit and offers a nominal cooling capacity of 2.50 kW and a nominal heating capacity of 3.20 kW.
This makes the system suitable for private living spaces, home offices, bedrooms, or comparable single-room applications where a fixed split air conditioning system with an outdoor unit is desired. The specific sizing must always be checked based on room size, insulation, window areas, heat loads, and installation conditions.
Technology & equipment
The indoor unit SRK25ZS-W is designed as a wall-mounted unit in high-gloss white. It features 4 fan speeds and achieves an airflow rate of 300 to 594 m³/h in cooling mode. In heating mode, the airflow rate of the indoor unit is 354 to 678 m³/h.
For air treatment, allergen filters, long-life filters, and photocatalytic filters are specified. The outdoor unit SRC25ZS-W2 operates with refrigerant R32 and is intended for mono-split operation with one indoor unit.
Everyday benefits
In everyday living and working, the air conditioning set combines cooling and heating functions in one system. The energy efficiency class A+++ in cooling mode and A++ in heating mode supports economical operation within the specified operating limits.
The indoor unit operates at the lowest cooling level with a sound pressure level of 19 dB(A), making it suitable for quiet rooms as well, provided the system is professionally sized and installed. The infrared remote control allows operation of the most important operating modes directly in the room.
System integration & compatibility
The set is configured as a mono-split system consisting of the indoor unit SRK25ZS-W and the outdoor unit SRC25ZS-W2. The outdoor unit is designed for connection to one indoor unit. The maximum refrigerant line length is 20 m, and the maximum height difference between the indoor and outdoor units is 10 m.
The refrigerant lines are executed with flare connections. 1/4 inch is specified for the liquid line and 3/8 inch for the suction gas line. Proper planning, installation, leak testing, evacuation, and commissioning must be carried out by qualified specialist personnel.

Installation
The installation of a split air conditioning system requires professional integration of the indoor and outdoor units, refrigerant lines, condensate drainage, and electrical supply. Refrigerant work, evacuation, leak testing, and commissioning may only be carried out by appropriately qualified specialist companies.
The electrical connection must be carried out in accordance with the applicable technical regulations. The information on line length, height difference, fuse protection, and pipe connections serves as product orientation and does not replace object-specific planning.
Notes
For reliable operation, the air paths on the indoor and outdoor units must remain clear. Filters and condensate drainage should be checked and maintained regularly. The outdoor unit must be positioned so that air intake, air discharge, and maintenance access are not obstructed.
The technical suitability of the system depends on room size, building insulation, solar radiation, internal heat loads, installation location, and mounting conditions. If in doubt, the sizing should be professionally reviewed before purchase.
