What is the HP of an Air Source Heat Pump?

The HP of an air source heat pump is an important indicator of its cooling or heating capacity, commonly used in equipment such as air conditioners and heat pumps. When selecting and calculating the HP of an air source heat pump, multiple factors need to be considered, including the cooling or heating capacity of the equipment, the operating environment, and actual needs.

Definition and Calculation Method of Air Source HP

1. Definition

Horsepower represents the cooling or heating capacity of an air source heat pump. For example, one HP of air source heat pump has a heating capacity of approximately 2500 watts (W), suitable for water tanks under 100 liters.

In the air conditioning industry, "HP" originally referred to input power, i.e., 1 HP = 735 watts. However, with technological advancements, it has gradually evolved into a unit of cooling capacity.

2. Calculation Method

Based on cooling or heating capacity: In Chinese standards, the formula for calculating air source HP is: HP = cooling (or heating) capacity / 232.4. The 232.4 here is a conversion factor, converting cooling or heating capacity from kilowatts (kW) to HP.

Based on Power Input and COP

Another calculation method uses power input and COP. The formula is: Horsepower = Power Input ÷ (3.51 × COP), where COP is the coefficient of performance of the heat pump, reflecting the cooling or heating efficiency of the heat pump.

Based on Area

A simple method is to use a conversion formula between area and capacity. For example, you can multiply the room area (square meters) by the floor height (meters), then divide by a fixed factor (such as 12 or 2.5) to determine the required capacity.

How to Check the Capacity of an Air Source Heat Pump Model

There are several ways to check the capacity of an air source heat pump model.

1. Official Website and Product Manual

Manufacturers typically provide detailed capacity information on their official website or product manual.

2. Cooling Capacity Calculation

By understanding the cooling or heating capacity of the unit, you can use the above calculation formula to determine the capacity.
