If you want to learn about the specific factors that determine the operating costs of air source heat pump heating, you can find a wealth of useful information in this article.
What factors have the greatest impact on the power consumption of an air source heat pump heating system? For this problem, it is estimated that most air source heat pump users first think of the air source heat pump host installed in their own homes. However, based on our years of research experience, we have given a different answer below.
Whether the building envelope is insulated is the fundamental
Under the condition that the room temperature of two air source heat pump heating users reaches 18 degrees Celsius, the energy consumption difference between the user with good house insulation effect and the two users with poor house insulation effect may behalf or even double. The power consumption of the air source heat pump heating system of the two users' homes will therefore behalf or even double the gap.
As we all know, the thermal insulation of the building envelope includes not only whether the wall is thermally insulated, but also the sealing and thermal insulation of doors and windows.
According to expert analysis, whether the doors and windows are leaking, whether it is an ordinary aluminum alloy or broken bridge aluminum, and whether the glass is single-layer or double-layer, will affect the power consumption of the air source heat pump heating system.
Whether the configuration of "air source heat pump heating system" is reasonable is the key
Apart from the thermal insulation performance of the building envelope, the most important factor affecting the power consumption of the air source heat pump heating system is the air source heat pump heating system itself.
The host in the user's eyes is only part of the "own factors" that affect the power consumption of the air source heat pump heating system. Even if the above-mentioned main engine has excellent performance, if the supporting devices such as the water pump and terminal system are not scientifically and unreasonably configured, the air source heat pump heating system will still be relatively "power-consuming".
In the opinion of experts, the "self-factors" that affect the power consumption of the air source heat pump heating system mainly includes the following two aspects:
1. Performance of the unit
2. The reasonableness of the relevant device configuration scheme
Reasonableness of the control system
If the unit, water pump, and terminal materials of the air source heat pump are regarded as the indispensable "hardware" to ensure the normal operation of the entire air source heat pump heating system, then the program that controls the operation of the relevant devices in the system can be regarded as the software. Just as "hardware" affects the power consumption of an air source heat pump heating system, "software" affects the power consumption of an air source heat pump heating system.
For example, the control of the defrosting logic by the units involved in the defrosting process of the system will affect the power consumption of the air source heat pump heating system. The defrosting in the heating process of the air source heat pump heating system is the opposite process of heating.
Because the compressor does work during the defrosting process but cannot provide heat to the room, it will consume more power. And after the defrosting is over, when the equipment is running again, it is necessary to heat the previously lowered temperature back to the temperature before the defrosting.
In this process, if the cooling consumes 10% of the time, it means that the equipment needs more than 20% of the time to complete the defrosting process. The shorter the defrosting time, the cleaner the defrosting equipment, the smaller the impact on the power consumption of the entire air source heat pump heating system. How to make the defrosting time as short as possible and the defrosting as clean as possible is related to the program of the air source heat pump for the detection of frost and the control of the defrosting logic.
When to defrost and what the metrics are will have a certain impact on operating costs. Therefore, different manufacturers control defrosting procedures and defrosting methods, which will have different effects on the power consumption of the entire air source heat pump heating system.
Whether the system installation is standardized is very important
For a set of "configured" well-configured air source heat pump heating systems, if it fails to get standard installation, this set of "configured" well-configured air source heat pump heating systems may also be relatively "power-consuming".
The installation of the heating end material is also important. Industry insiders pointed out that before installing the terminal type of the air source heat pump - the radiator, the installation of indoor and outdoor pipes should be scientifically designed.
Because the reasonable layout of the pipeline will directly affect the heating effect of each room. Once the number of radiators and the installation of pipes are unreasonable, the room temperature will be uneven in each room.
Under such conditions, even if the outlet water temperature is increased, it will only increase the indoor temperature, but cannot solve the phenomenon of room temperature difference in each room. In order to make up for the temperature of the "shortboard" room, the room with the room temperature that meets the standard will also heat up at the same time, causing energy loss to a certain extent and increasing the user's heating costs.
At the same time, it is necessary to appropriately increase or decrease the number of radiators according to the different needs of homeowners for different room temperatures. Use fewer radiators in rooms with low heating needs to avoid wasted heat loss.
In summary, there are many factors that affect the operating cost of air source heat pumps. Once the configuration of the entire system is unreasonable, even if the technology of the equipment is advanced enough, the energy consumption will not necessarily be low. The final result is not only reflected in the difference in heating effect, but the most direct reflection is the impact on operating costs.
