With the increasing awareness of environmental protection and the country's strong support for heating engineering renovation projects, people are increasingly aware of giving up cheap heating methods. 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 an air source heat pump system, 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
Principles for selecting air source heat pumps 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 24HP units can be used instead of one 48HP unit to ensure the stability of the system. 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 pipe. Generally speaking, seamless galvanized steel pipes are recommended for outdoor use and PPR pipes are recommended for indoor use. Generally, the water pump is used in a one-for-one principle. The flow and head of the water pump are calculated based on parameters such as load and heating pipes.
4. Design system
After the air source heat pump model is finalized, the system diagram can be drawn in accordance with the relevant national standards of HVAC.
5. Energy-saving optimization
Air source heat pump heating should optimize the system, 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 utilize energy.
