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 continuously throughout the day. They operate at high pressure and temperature to meet the entire family's hot water needs while consuming minimal energy. In addition to efficient hot water production, these systems can also function similarly to air conditioners by releasing cool air to help regulate temperatures in areas like the kitchen. Moreover, they can be used in spaces such as balconies, storage rooms, or garages to dehumidify the environment, preventing mold growth on items or accelerating the drying of clothes.
During operation, the power consumption of an air-source heat pump may fluctuate, sometimes appearing excessively high. Several factors could contribute to this issue:
1. The voltage supplied to the heat pump may not meet the required operational standards.
2. The water volume might be unsuitable, or a drop in water temperature could increase the workload for heating.
3. There could be a malfunction in the sensing circuit.
To address these issues:
1. If the unit stops running due to a control system problem, check the set protection parameters, such as the water temperature control circuit. If the system fails to collect signals, the unit won’t start. This is because the unit initiates operation based on the temperature of the heat exchanger, collector, and the set temperature. If the data from the water tank is insufficient, the unit enters a protective mode and won’t start.
2. Low or high voltage can prevent the unit from starting properly. First, check if the compressor is damaged, then confirm there’s no damage and recheck the data to make necessary corrections. Additionally, ensure that the electromagnetic valve control, water level sensitivity, and pressure levels are functioning correctly to avoid any issues related to water level data.
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 compressed air then transfers heat through a refrigerant that boils at -17°C, moving heat into the water tank and finally releasing it into the water for use.
