Hisense ENERGY PRO X QH35XV4A 3.5/4.0 kW air conditioner / heat pump, matte white, Wi-Fi, R32

Hisense ENERGY PRO X QH35XV4A is a high-efficiency inverter Split air conditioner and air-to-air heat pump designed for room cooling, heating, dehumidification and ventilation. The system consists of the QH35XV4AG indoor unit and the AS35XV4EW outdoor unit. Its understated matte-white indoor unit is suitable for contemporary homes as well as office interiors.

Nominal cooling capacity is 3.5 kW with a modulation range of 1.0–4.4 kW; nominal heating capacity is 4.0 kW with a range of 1.6–4.8 kW. Seasonal ratings of SEER 8.5 and SCOP 5.1 correspond to an A+++ rating for cooling and heating in the average climate zone. The inverter compressor adjusts output to actual demand to maintain steady temperatures and reduce unnecessary energy use.

ENERGY PRO X is designed to operate in cold weather as well. The manufacturer specifies an outdoor heating operating range of -22 to +24 °C and a cooling range of -15 to +43 °C. Automatic defrosting and an electrically heated outdoor-unit chassis help maintain operation in winter conditions. An 8 °C frost-protection heating mode is also available for periods when the building is unoccupied.

HI-NANO technology and multi-stage air filtration help improve indoor air quality. The filtration equipment includes an activated-carbon filter and a four-in-one assembly featuring vitamin C, catechin, silver-ion and HEPA filter elements. 4D automatic airflow controls both horizontal and vertical louvers; Smart Airflow adapts air delivery to the selected mode, while Follow/Avoid directs the airflow towards or away from occupants.

Built-in Wi-Fi allows remote control through a compatible smartphone application. AI Smart and TMS Comfort Control help adapt indoor climate settings automatically; compatible voice assistants can also be used. Comfort features include I Feel temperature sensing at the remote control, Turbo mode, four sleep profiles, a 24-hour timer, automatic restart, self-diagnostics and Dual Self-Clean cleaning technology.

The indoor unit offers 7 fan speeds and an airflow range of 410–650 m³/h, with dehumidification capacity of 1.2 l/h. The ultra-quiet setting reaches 18 dB(A), while the manufacturer lists 30–38 dB(A) for standard sound-pressure measurements. The indoor unit measures 877 × 301 × 194 mm, allowing straightforward integration into different room layouts.

The system uses R32 refrigerant, which has a lower global-warming potential than R410A. Maximum refrigerant pipe length is 20 m and the permitted height difference between units is 10 m. The liquid-line connection is 6.35 mm (1/4") and the gas-line connection is 9.53 mm (3/8"). It is a practical option for efficient year-round room cooling and heating in homes, offices and other indoor spaces.
