Key Players:

=> Danfoss, Lennox International Inc., Robert Bosch GmbH, NIBE Industrier AB, Glen Dimplex Group, and FUJITSU GENERAL

Key Developments:

✅ October 2025: Mitsubishi Heavy Industries (MHI) Thermal Systems won the 2025 GOOD DESIGN AWARD for its Hyper Multi LXZ series multi-split air conditioner. The system uses R32 refrigerant and features a refined design that fits various installation environments, integrating well into urban areas.

✅ September 2025: A Japanese research team examined the affordability of photovoltaic-battery systems with heat-pump water heaters and air conditioning units across nine regions of Japan. The study found a tradeoff between net demand and cost depending on the solar-plus-storage system's capacity.

✅ August 2025: Daikin launched the EWWH-VZ water-cooled chiller and heat pump system, designed for industrial buildings and district heating. The system uses Daikin's single screw compressors that have variable volume ratio (VVR) technology, which can adjust the internal volume ratio based on the unit's operating conditions.

✅ July 2025: The adoption of heat pumps in Japan is encouraged by policy support from the Green Transformation (GX) Roadmap, rising electricity prices, and fast product innovation in high-efficiency compressors.

Recent Mergers and Acquisitions (M&A):

✅ August 2025: Daikin completed the acquisition of DDC Solutions, a company that specializes in AI data analytics for HVAC systems. The acquisition aims to improve Daikin's capabilities in smart building solutions and predictive maintenance.

✅ July 2025: Paloma Rheem Holdings finished acquiring Fujitsu General's air conditioning business, including its heat pump product line. This acquisition is expected to bolster Paloma Rheem's position in the Japanese HVAC market.
