Why Should I choose inverter when Buying an Air Source Heat Pump?
2026-05-22
We have entered a period of large-scale purchases of air source heat pumps, and in the household heat pump market, up to 96% of consumers will choose to buy inverter air source heat pumps! Why do most people prefer inverter air source heat pumps? If you know something about air source heat pumps, you will definitely choose inverter air source heat pumps!
What is inverter air source heat pump?
Fixed frequency air source heat pumps operate at fixed power and adjust the indoor temperature by frequently turning the machine on and off. Therefore, its cooling and heating speeds are relatively slow, resulting in large fluctuations in indoor temperature. In contrast, inverter air source heat pumps have a wider operating voltage range, small starting current, and can quickly reach the set temperature at high power, maintain room temperature balance at low power, so cooling and heating are fast, power saving, and room temperature fluctuations are small.
What are the advantages of inverter air source heat pumps?
1. Overclocking and powerful output, more efficient heating and cooling
The power output capacity of inverter air source heat pump is stronger than that of fixed frequency heat pump, which can quickly reach the design value, and can easily achieve the effect of rapid cooling in summer and strong heating in winter.
1) Stronger and more comfortable heating in winter
In the extremely cold winter environment, inverter air source heat pump can operate through overclocking, and the heating capacity can exceed the rated value by about 30%. It has stronger and more stable low-temperature heating capacity than fixed frequency heat pump; it can not only meet the normal heating needs under rated conditions, but also meet the heat needs in ultra-low temperature climates, making the winter heating effect stronger.
2) Faster and healthier cooling in summer
In the hot summer, inverter air source heat pump can operate through overclocking. During the start-up phase of the heat pump, it works at a higher frequency, quickly reaches the set value, and then reduces the operating frequency to maintain the temperature, which greatly reduces the cooling time.
2. Avoid starting and stopping, and minimize energy consumption
When the fixed-frequency air source heat pump reaches the set value, it will stop working, and when the room temperature drops/rises, it will start working again, so there will be frequent start and stop phenomena during use, resulting in increased energy consumption.
When the indoor temperature reaches the set value, the variable-frequency air source heat pump will enter low-frequency operation. When the winter heating is running for a long time, the variable-frequency host runs stably at a low frequency, the working conditions are relatively smooth, and there is less frost, which reduces the energy consumption of reverse operation during defrosting, and can start normally under low temperature and low pressure conditions, without temperature difference, which can bring a better comfortable experience.
Not only that, the variable-frequency heat pump can also automatically adjust the compressor operating frequency according to the changes in ambient temperature, and can maintain high heat exchange at any time, providing as much heat as needed, without generating excess waste. Therefore, compared with the fixed-frequency heat pump, the variable-frequency air source heat pump saves more than 20% energy.
3. Adjustment without shifting gears to achieve constant indoor temperature
The fixed-frequency air source heat pump will shut down after reaching the set temperature, and it cannot keep the water temperature constant. Such a temperature is not obvious if used in a large space, but if it is used in a small space or a home room, it will cause the room temperature to fluctuate. The variable-frequency air source heat pump will continue to run at a low frequency after reaching the set temperature to maintain the stability of the indoor temperature. The temperature control accuracy of the variable-frequency machine is ±0.1℃, which can achieve true constant temperature control, and the human body can hardly feel the fluctuation.
Final summary
Through the above analysis, it can be seen that the air source heat pump using variable-frequency technology can make the room quickly reach the required temperature in a short time compared to the fixed-frequency heat pump, and fluctuate with a small temperature difference under low speed and low energy consumption, achieving the effect of fast, energy-saving and comfortable temperature control.

Does the Air Source Heat Pump use Two-Phase or Three-Phase Electricity?
2026-05-08
With the enhancement of environmental awareness and the continuous advancement of energy utilization technology, air source heat pumps, as an efficient and energy-saving hot water supply and heating and cooling system, are gradually favored by more and more families. However, when purchasing air source heat pumps, a common question is whether to choose two-phase electricity (mostly single-phase electricity in practice) or three-phase electricity. This article will discuss this issue from multiple angles to help consumers make a wise choice.
First of all, we need to clarify the basic concepts of single-phase electricity and three-phase electricity. Single-phase electricity refers to a power supply method in which there is only one AC voltage source and one neutral line in the power system. Its voltage is usually 220V and is widely used in homes and small commercial places. Three-phase electricity refers to a power system with three phase voltage sources, which are 120 degrees apart from each other. The voltage of each phase is also usually 220V, but the voltage between the three phases is 380V, which is widely used in industry and high-power equipment.
Next, we analyze the application characteristics of the two power supply methods in air source heat pumps. Single-phase electric air source heat pumps are suitable for home and small commercial users. They have low installation costs, simple power wiring, and low construction difficulty. In addition, since the electricity demand of home and small commercial users is relatively small, single-phase electric equipment can already meet daily heating and cooling needs. However, single-phase electric equipment has large line losses when transmitting high power, and is prone to problems such as unstable voltage and excessive current, which may affect the normal operation and life of the equipment.
In contrast, three-phase air source heat pumps are more suitable for industrial users and high-power equipment. The three-phase power system can provide more stable power output, less voltage fluctuations, and can distribute current loads and reduce power losses. This makes three-phase electric equipment more efficient and stable during operation, which can reduce operating costs. In addition, the startup and operation performance of three-phase electric equipment is generally better than that of single-phase electric equipment, especially under high load conditions. However, the installation cost of three-phase electric equipment is high, the power wiring is complex, and the construction is difficult, requiring professional power engineers to design and install.
Leomon air source heat pump is compatible with a variety of terminals and supports various forms including floor heating, air disc and radiator, providing users with more comfortable cooling and heating effects and diverse choices. The air source heat pump occupies a small area and has the characteristics of dual use in one machine, which saves equipment installation space.

What is a Mini Split Air Source Heat Pump?
2026-05-01
A mini split air source heat pump is a ductless HVAC system designed to provide heating and cooling to individual zones or rooms. Unlike central air conditioning systems that rely on extensive ducting, mini split air conditioning systems consist of two main components: an outdoor compressor and one or more indoor air handling units connected by refrigerant lines.
These systems are ideal for situations where ducting is not an option, such as older homes, home additions, or small commercial spaces. Ductless mini split heat pumps offer flexible zoned climate control, allowing you to customize the temperature of different rooms independently, saving energy and increasing comfort.
How do mini split air source heat pumps work?
Like all heat pumps, mini split air conditioners work by transferring heat rather than generating it. Here is a brief breakdown of their components and how they work:
How a Mini Split Air Source Heat Pump Works
1. Compressor (outdoor unit)
Pressures the refrigerant and circulates it through the system.
2. Evaporator coil (indoor unit)
Absorbs heat from indoor air when cooling and releases heat when heating.
3. Expansion valve
Regulates refrigerant flow.
4. Refrigerant lines
Connects indoor and outdoor units and delivers refrigerant.
5. Fan and filter
Delivers treated air to the room and captures dust.
Mini split air source heat pump systems operate in reverse depending on the season - extracting heat from indoor air and transferring it outside in the summer, or absorbing heat from outdoor air and bringing it indoors in the winter. Advanced models such as the Leomon mini split air source heat pump also integrate an inverter-driven compressor, allowing it to adjust power usage based on demand, thereby improving energy efficiency and comfort.

Can the Flower Market use Air Source Heat Pumps?
2026-04-24
People who grow flowers know that most flowers are very delicate. When the temperature is low in winter, the flowers may freeze to death; when the temperature is high in summer, the flowers may die of heat, especially the higher the level of flowers, the more difficult it is to maintain, and the higher the temperature requirements. Therefore, heating and cooling are equally important for the flower market.
With the development of science and technology and the promotion of the national "coal to electricity" project, the Xi'an flower market began to seek cleaner, more environmentally friendly, safer and more stable clean heating equipment. Leomon has won the favor of the project with its ultra-low temperature heating and high-efficiency energy-saving air source heat pump.
1. Dual use for cooling and heating
Flowers are not only afraid of cold, but also heat. In the past, when coal-fired boilers were used for heating, indoor air conditioners needed to be installed to cool the market in summer. The air source heat pump integrates heating and cooling. One heat pump can meet the two needs of heating in winter and cooling in summer. Whether it is a severe winter or a hot summer, it can maintain a stable environment like spring in the flower market all year round and improve the quality of flowers.
2. Constant temperature and convenience
Flowers are very sensitive to ambient temperature, and the market environment needs to be heated up in winter and cooled down in summer. The air source heat pump adopts an intelligent remote control system, which can intelligently control the temperature, automatically turn on and off the machine, etc., and does not require special personnel to watch, saving labor management costs, and the equipment is stable and reliable during operation, and the maintenance cost is relatively low.
3. Ultra-low temperature heating
Considering the extremely low temperature in the local winter and the long heating period, the air source heat pump used in the project is a 60P air source heat pump specially developed by Leomon for the extremely cold environment in northern winter. It is equipped with ultra-low temperature jet enthalpy increase, intelligent defrosting and antifreeze and other top industry technologies, and can still operate stably in a low temperature environment of -35℃.
4. Energy-saving and economical
The air source heat pump does not burn electricity, but relies on a small amount of electric drive machine to absorb a large amount of free heat energy in the air to heat. 1 part of electricity can absorb and convert 4 parts of heat energy. It is a heating equipment with higher heating efficiency on the market and is more energy-saving to use.
Final effect
After the flower market switched to air source heat pumps, it has been running for a cooling and heating season, and the effect is good, which meets the constant temperature and energy saving needs of the flower market very well, and has been well received and favored by users.
