Classification and Characteristics of Air-Source H
Air-source heat pump units are mainly divided into two types: normal temperature type and low temperature type, based on their design and performance differences. There are significant distinctions between the two in terms of operating temperature range, structural design, and applicable environments.
Parameter/Type | Normal Temperature Heat Pump | Low Temperature Heat Pump |
Operating temperature range | -10℃ to 43℃ | -35℃ to 48℃ |
Applicable environment | It is mainly suitable for regular cooling and heating demands. | It is suitable for applications requiring operation under extreme temperatures. |
Design features | Optimized compressor and heat exchanger design for regular temperature ranges | Additional heating and anti-freeze features to ensure stable performance at very low temperatures |
Energy efficiency ratio (IPLV) | Higher efficiency, suitable for standard energy efficiency requirements. | Slightly lower than normal temperature type, but optimized for low temperatures. |
The operating capability of low-temperature air-source heat pump units under extreme temperatures is their most prominent feature. Unique design aspects include optimizations to the compressor and heat exchanger, as well as special adaptations for low-temperature environments. Equipped with additional heating and anti-freeze functions, the equipment can initiate a preheating program in extremely low temperatures to prevent the refrigerant from freezing in the pipelines, ensuring the system can start and operate normally.
The heat pump has a compact design, occupying minimal space with an optimized pipeline layout to enhance efficiency.
Its standardized installation process allows for fast setup, reducing both time and maintenance costs.
The heat pump is equipped with an advanced control system that monitors real-time environmental changes and adjusts the compressor output to match heating or cooling demands.

Application
Home Heating: Air-source heat pumps are widely used for home heating, especially in areas with high heating demand in winter. Due to its energy-saving and environmentally friendly characteristics, air-source heat pumps are considered an ideal heating method.
Decentralized Heating Field: In areas with hot summer and cold winter, air-source heat pumps are the best choice for decentralized heating markets, gradually replacing small and medium-sized coal-fired boilers to reduce energy waste and air pollution.
Livestock Heating Farm: Air-source heat pumps are also widely used livestock industry for raising pigs, fish, shrimp, and other animals. Their intelligent temperature control and labor-saving features give them significant advantages in this field.
Heating and Cooling for Large Buildings: Air-source heat pumps not only provide heating but also have cooling functions, making them suitable for the heating and cooling needs of large buildings. Their cooling performance surpasses traditional central air conditioning systems.
Constant Temperature Agricultural Greenhouses: In cold areas, air-source heat pumps are used for temperature control in vegetable and fruit greenhouses to prevent low temperatures from affecting crop growth.
Commercial Water Heaters/Commercial Heat Pumps: Air-source heat pumps are suitable for heat pump water heater retrofit projects in hotels, guesthouses, schools, hospitals, and other places, providing year-round intelligent management with higher safety than traditional boilers.
Campus Hot Water Projects: Air-source heat pumps are ideal for campus hot water projects, providing 24-hour hot water supply to enhance the level of school logistics services and improve school facilities.
Industrial Field: Air-source heat pump technology is also used in industrial applications for waste heat recovery and process heating, further expanding its range of applications.
Equipment Maintenance Instructions
The controller is equipped with a "System Maintenance" function, which is used to limit the operating time of the unit. Once the system maintenance time is reached, the unit will be forcibly shut down and cannot be restarted until the system maintenance is disabled. The anti-freeze function remains unaffected during system maintenance. The "System Maintenance" function is disabled by default.
The "Accumulated Operating Time of the Unit" is counted in hours and converted into "days" when calculating the "System Maintenance Time" (note: this is the operating time divided by 24 hours, not the actual number of days).
When the "System Maintenance" function is enabled, a system maintenance reminder function is activated to avoid sudden forced shutdowns that may inconvenience users. When the remaining operating time of the unit is >168 hours (7 days), the unit operates normally without any reminders. When the remaining operating time of the unit is ≤ 168 hours (7 days), the reminder rules are as follows:
The unit is powered on again.
The scheduled reminder time is reached.
Whenever one of the above two conditions is satisfied, the remaining running time will be reminded.
