1. The supply water temperature and return water temperature of underfloor heating system should be determined by calculation, the supply water temperature should not exceed 60°C, civil buildings supply water temperature should be around 35℃ to 50℃, temperature difference should not exceed 10℃. 2. Average temperature of ground surface (℃) Area Suitable range(℃) Highest limit(℃) People […]

1. If the buffer tank is not set, the heat pump unit will start and stop frequently. Especially when the indoor terminal is a radiator or a fan coil, which the amount of circulating water in the loop is limited,  will cause the heat pump to reach the design temperature in a short time, the heat

At present, the north has entered the heating period of the new season. As the temperature drops, ensuring heating has become a top priority. Antifreeze measures for air source heat pump in winter, it can be carried out from the following aspects. Heat pump antifreeze measures one: Strengthen the insulation effect of the pipeline.It is very

We all know that the heat preservation and antifreeze measures of the air source heat pump unit for heating in winter are very important, and a little carelessness will bring direct economic losses to users, and even produce more serious consequences. “Learning from history”, which reasons will lead to heat pump inner system crack and freeze? Here

1. What is ground source heat pump system? Ground source heat pump is a kind of high-efficiency and energy-saving air-conditioning system that uses the shallow earth resources (including soil and ground water, surface water, or urban reclaimed water) to supply hot water and also cooling. It uses heat exchange pipes laid in the soil and surface
