Introduction to GENT fixed frequency air source heatpumps Fixed frequency air source heatpumps is a type of air source heat pump. All heat pump products under this category operate at a fixed frequency. After reaching the setting, the unit will be completely shut down and restarted when the temperature deviation is large. The products included in the category of fixed frequency ashp heat pump are mainly fixed frequency heat pump hot water heater, fixed frequency air source heating system, and fixed frequency Heat Pump Heating And Air Conditioning unit. These three products are relatively basic products in air source heatpumps. Although they have slight differences in use purposes and working modes, in essence, these products all use the heat in the air as the cooling or heating source, and achieve building cooling or heating by absorbing heat in the air. They are all air and water heat pump. Suggestions on whether to choose a fixed frequency unit or an inverter unit 1. Limited budget: Choose a fixed-frequency unit, which is suitable for intermittent use or scenarios that are not sensitive to temperature 2. Long-term use/high comfort requirements: give priority to Inverter Heat Pump, which can save electricity bills in the long term and improve user experience 3. Extreme climate areas: Choose EVI inverter unit to ensure low temperature performance Therefore, when choosing a unit, users need to consider many factors comprehensively, such as your own usage needs, purchase budget, usage frequency, local climate, energy available for the unit, actual on-site conditions, etc. Only after clarifying these conditions and combining the characteristics of each product, users can choose the unit that suits you best.
