Analysis of the causes of excessive air heat pump power
Air-source heat pumps, as the name implies, utilize energy from the air to generate heat and provide hot water 24/7. These systems operate under high pressure and temperature to meet the entire family’s hot water needs while consuming minimal energy. In addition to efficient hot water production, they function similarly to air conditioners by releasing cool air to regulate indoor temperatures, especially in kitchens. They can also be used in areas like balconies, storage rooms, or garages to dehumidify the space, preventing mold on items or speeding up the drying of clothes.
During operation, the power consumption of an air-source heat pump may fluctuate, sometimes appearing too high. This issue often arises due to several reasons: first, the voltage supplied may not meet the system's requirements. Second, improper water levels or a drop in water temperature can increase the workload on the unit. Third, there might be a problem with the sensing circuit.
To address these issues, first, if the unit has stopped running, check the control system for any set protection parameters, such as the water temperature control circuit. If the system fails to collect signals, the unit will not start. The unit is designed to activate based on the temperature of the heat exchanger, collector, and water tank. If the data collected is below the set threshold, the unit enters a protective state and won’t start.
Second, if the voltage is too low or too high, the unit may not boot properly. At this point, it’s important to check whether the compressor is damaged. If no damage is found, recheck the system data and make necessary corrections. Additionally, the electromagnetic valve and water level sensitivity should be inspected to ensure that the water level data is accurate and not causing the issue.
An air-source heat pump operates based on the "reverse Kano" principle. To put it simply, the outdoor unit acts like an air compressor, compressing air to raise its temperature. The refrigerant, which boils at -17°C, absorbs heat from the outside air and transfers it into the water tank, where it releases the heat and warms the water. This process makes the system highly efficient and environmentally friendly, offering a sustainable solution for both heating and cooling needs.
