original title: comparison of variable frequency air energy heat pump and ordinary heat pump
the power of ordinary air energy heat pump is the same when it starts up. No matter how big the temperature difference in the water tank is, the external machine will operate at high power until the set temperature is reached. What is the difference between variable frequency air energy heat pumps? What are the advantages and disadvantages of ordinary heat pump?
how to understand the variable frequency air energy heat pump?
the power of variable frequency air energy heat pump can be adjusted automatically, and the operation power can be pool heat pump adjusted according to the temperature difference and other factors in a small and large range, so as to achieve the purpose of power saving.
generally speaking, we can use the example of driving to compare: the oil is compared to the electricity charge, the engine is compared to the compressor, the starting point is compared to the initial temperature of the water tank, the end point is compared to the set temperature, and the driver is compared to the control system.
the common air energy heat pump is like a driver who can only step on the accelerator and the brake to the end. When starting from the starting point, one foot of the accelerator will be pressed to the bottom, and the accelerator will be kept on the way until reaching the end point. In this way, the fuel consumption ratio will be higher, which is equivalent geothermal heat pump to the higher electricity cost.
comparison of advantages and disadvantages between frequency conversion and fixed frequency
1. Frequency conversion is more energy-saving
because the indoor and outdoor temperature at night is variable and unsteady when heating. When the indoor temperature is high, the constant frequency still operates at high energy rate, while the frequency conversion automatic adjustment adapts to the indoor temperature, and the energy saving effect is better.
2. The comfort of frequency conversion is better
because the acceleration of frequency conversion temperature change is low, while the acceleration of constant frequency temperature change is larger, the change of body feel of constant frequency is obvious, and the frequency conversion is more comfortable and natural change, which is more conducive to health.
