на подачу пускает 55 градусов, вот и результат
Если не ошибаюсь, то оригиналом CH-HP 16 MIRM является GREE VERSATI Ⅲ Air To Water Heat Pump.
В описании упоминается +55/+60
1.3.1 General
It is a kind of integrated DC inverter that includes cooling, heating and water heating functions, and up to 5.0 energy efficiency. It adopts R32 refrigerant and two stage compressor. For heating, the ambient temperature range is -25 ~ 35 while while the leaving water temperature range is 25~60℃.
The Versati ⅲ unit is specially designed for the European market where there is a demand for water at high temperatures. Thanks to the dual-stage compression, and enthalpiewinst due to gas injection, the energy efficiency of heating at low temperature to rise sharply, with the temperature up to 60°C., and The entire range of products complies with the strict EN14511, EUROVENT Energy efficiency class A, and the SCOP Class: A+++(35 ° C), SCOP-Class: A++(55 ° c), with EN14825. Their agent can reach 5.0. This unit can realize space heating and sanitary hot water supply through end units, such as the fan coil unit, floor coil and radiator. Environmentally friendly refrigerant R32 is approved for the unit, with ODP of 0 and relatively low GWP (=675). In addition, the heat pump technologies used will reduce the consumption of coal and other energy sources and significantly reduce CO2 emissions. Ranged from 4.0 kW~16kW, it is widely applicable to small and medium apartment, large villa etc.
Но в мануале не нашел схем подключения батарей, там только низкотемпературные полы, поэтому можно предположить, что выше +35 - это уже прямой электрический догрев или периодический не очень эффективный режим ТН.
Поэтому большой вопрос, как подключали к радиаторам, где должно быть постоянно не менее +55. И какая эффективность системы при этом.
