There are more and more ways of heating in winter, from the development of heating fuels such as burning wood, coal, gas, and electricity. With the continuous advancement of technology, more and more users choose air source heat pumps for heating and cooling.
05 Is it necessary to add antifreeze in an air source heat pump heating system?
Antifreeze can be added to the air source heat pump heating system, and the corresponding proportion of antifreeze can be added according to the size of the heating area. If air source heat pump heating is applied in low-temperature environments in the north, antifreeze must be added to prevent the pipeline from freezing, cracking, and damaging the heat pump host after cooling; If air source heat pump heating is applied in high temperature environments in the south, antifreeze does not need to be added. The average winter temperature in the south is almost always above 0 ℃, and the possibility of pipeline icing is very low. However, protective agents should be added to the heating system to prevent scale formation, delay the scaling of heating water, and prevent corrosion of heat pump system components.
06 How Should Air Source Heat Pumps Be Used Correctly During The Heating Season?
When the ambient temperature drops below 0 ℃, there is a risk of the heating circulating water freezing without heating, which can easily damage the pipelines and heat pump units. If you leave home for a short heating period of time (within 3 days), you can set the temperature of the unit to the lowest. At this time, the air source heat pump will operate at low load and have the lowest energy consumption. However, you must not turn off the power to the heat pump unit because it has anti freezing protection function. If there is a power outage, the heat pump host will not be able to start the anti freezing protection function, which will lead to pipeline freezing and damage to the heat pump host. If there is no one at home for a long time, the water in the air source heat pump heating system can be completely drained to reduce the damage of low-temperature environment to the pipeline and heat pump host. Of course, if it is in the southern region, it is not necessary to drain the circulating water in the pipeline, and it is also feasible to directly cut off the power. The temperature in the southern region is not enough to cause pipeline freezing and heat pump host freezing damage.
During the normal operation of the air source heat pump, attention should be paid to the discharge of condensate water, especially the installation method where the condensate water is discharged very close to the heat pump host. In low-temperature environments, the condensate water of the air source heat pump will freeze faster, which will then extend to the inside of the heat pump host, causing the condensate water to freeze inside the heat pump host and damage the components of the heat pump host. At this time, it is necessary to clean the drainage environment around the condensate drainage pipe in a timely manner, keep the condensate drainage unobstructed, and ensure that it will not affect the operation of the heat pump host after freezing. When installing the heat pump host, the height between the heat pump host and the ground can also be increased, and insulation materials and heating devices can be used to cover the condensate pipe to prevent it from freezing.
After the heating season, the air source heat pump heating system can be maintained by cleaning the scale and impurities in the pipes, as well as removing dust, fluff, and other debris from the heat pump host to improve its efficiency. If the air source heat pump is only used for heating, the unit can be turned off or the heating water in the pipeline can be drained; If the air source heat pump is equipped with a fan coil unit, it can provide comfortable air conditioning for indoor use in summer. However, it is necessary to clean and disinfect the fan coil unit before use.
07 What Should I Do If The Temperature Of An Air Source Heat Pump With Underfloor Heating Cannot Rise For A Long Time?
There are many reasons why the temperature of the underfloor heating system cannot rise for a long time, usually including the underfloor heating valve not being opened, abnormal power supply of the heat pump unit, low water supply temperature setting, low indoor temperature setting, large temperature difference of the indoor temperature controller, high indoor humidity, poor insulation of the house, insufficient heat at the end of the heating system, and frequent switching of the heat pump unit. Of course, there is also a phenomenon where the ambient temperature is too low, causing the air source heat pump unit to fail to operate. In this case, it is necessary to choose a low-temperature air source heat pump according to the operating environmental conditions.
08 How To Use Air Source Heat Pumps More Energy-Efficient?
To achieve more energy-efficient air source heat pump heating, first of all, the selection of equipment should be appropriate. If the power of the heat pump unit is too small, it will definitely consume more energy. If the power of the heat pump unit is too large, the output power will also consume a lot of energy; Secondly, it is important to pay attention to usage habits and not excessively pursue higher room temperatures. The underfloor heating temperature should be set within a reasonable and comfortable temperature range; Then, pay attention to the insulation of the house during use. During the use of underfloor heating, indoor insulation measures should be taken to reduce the ventilation time and opening frequency of windows; Again, do not frequently turn on and off the heat pump host, as it may seem to save on the cost of underfloor heating. However, frequently turning off the underfloor heating can cause rapid loss of indoor heat, and reheating to increase temperature requires more heat consumption; Finally, regular maintenance of the air source heat pump is beneficial for the efficient operation of the heat pump host.
Summary
With the increasing number of heating methods, air source heat pumps have gradually entered the heating industry. Due to their high environmental friendliness, strong energy efficiency, stable performance, high heating comfort, multifunctionality, and long service life, air source heat pumps are favored by more and more people. However, air source heat pumps have not been used in the heating industry for a long time, so we need to have sufficient understanding of air source heat pumps in order to better serve us.
