As the policy of "coal to electricity" has been deeply rooted in the hearts of the people, the public's awareness of environmental protection has increased, and the country has strongly supported heating engineering renovation projects. The awareness of giving up cheap heating methods has become stronger and stronger. What issues should be paid attention to when choosing air source heat pump heating?
1. Look at the site and know the parameters
When customers intend to use air source heat pump systems, we need to understand the geographical location parameters on site (the coldest average temperature in winter, the lowest extremely cold weather temperature, the average maximum temperature in the hottest month in summer, and the highest extremely hot weather temperature), building parameters (building age, insulation conditions, cold and hot load parameters, number of floors, floor height, number and size of rooms, pipeline and terminal parameters and mathematics); electrical parameters (power parameters and volume of transformers, current parameters and length of cables)
2. Calculate the load
According to the heating area, number of rooms and temperature requirements of the building, calculate the equipment parameters and quantity of the air source heat pump heating terminal, and finally calculate the total cold and hot load of the building.
3. Equipment selection
A: Principles for heat pump host selection After the total cold and hot load of the building is selected, the number of heat pumps is calculated based on the floor area and single power. Generally, double is preferred rather than single. For example, two 24-HP machines can be used instead of one 48-HP machine to ensure the stability of the system.
B: Pipe and water pump selection
After the cold and hot load of the building is calculated, the pipe diameter can be calculated based on the economic flow rate and flow of the pipeline. Generally speaking, seamless galvanized steel pipes are recommended for outdoor use and PPR pipes for indoor use. Generally, the water pump is used as one standby and one for use. The flow and head of the water pump are calculated based on parameters such as load and heating pipes, and a surplus of about 10% is added in the end.
4. Design system
After the main equipment is finalized, the system diagram can be drawn in accordance with the relevant national standards of HVAC.
5. Energy-saving optimization
The air source heat pump heating system should be optimized, such as the installation position of the fan disc, the installation position and size of the water tank, etc.
Air source heat pump heating does not require artificial cold and heat sources, and can replace traditional heating methods such as boilers or municipal pipe networks and central air conditioning systems. At the same time, it can also supply domestic water, which can be said to kill three birds with one stone and is an effective way to use energy.
