Gree Versati III SPLIT 4.0/3.8kW, S1GRE- Air-to-water heat pump indoor unit

The Gree Versati III SPLIT 4.0/3.8kW indoor unit is a reliable and efficient third-generation air-to-water heat pump indoor unit. The device is designed for heating, cooling, and domestic hot water preparation systems. The Versati III series stands out for its durability, favorable price, and consistently high efficiency even at low outdoor temperatures. The package includes a three-way valve, room thermostat (temperature sensor), water heater controller, signal cable between the indoor and outdoor units, coarse filter, and an outdoor unit bottom plate heating cable.

This heat pump indoor unit is used as the main energy collection component, transferring heat from the environment into the internal heat pump system. The maximum efficiency of the device reaches up to 5.10, and the electrical power consumption is up to 780 W, enabling the indoor unit to utilize electricity highly efficiently for heating and cooling processes. The SPLIT model does not have an integrated domestic hot water tank but is designed for connection to an external hot water cylinder. The water supplied to the system can be heated up to +60°C.

The device also features a durable construction and corrosion protection, making it suitable for operation in various climatic conditions. The heat pump operating parameters at T=+7 °C/+35 °C are: nominal heating capacity (underfloor heating): 4 kW. The device also features an exceptionally high coefficient of performance (COP) of up to 5.1, and a COPd of 6.39 (A7/W35 °C). The cooling capacity of the device (underfloor cooling) at T=+35°C/+18°C is 3.8 kW, with a coefficient of performance (EER) of up to 4.63. The unit also features an integrated touch-sensitive control screen and built-in WiFi. The refrigerant used in the device is R32.

The integrated plate heat exchanger guarantees excellent heat transfer efficiency and resistance to thermal fluctuations. This is crucial for maintaining stable operation over many years. This series unit is compatible with hydraulic modules and boilers, allowing this block to be used in various system configurations.
