The YIERP heat pump split unit consists of two parts: an outdoor main unit and an indoor heat exchange terminal. The heat pump split unit can provide heating, cooling, and domestic hot water, allowing the low-grade thermal energy in the air to be fully utilized and effectively converted into high-grade thermal energy.
Load Adaptive Adjustment
The YIERP heat pump split unit monitors indoor and outdoor temperatures, water temperature, and load changes in real time, then adjusts the compressor frequency, fan speed, and expansion valve opening to achieve "heating/cooling on demand," with an energy-saving rate 30%-40% higher than fixed-frequency models.
Low-Temperature Defrost Control
The YIERP heat pump split unit has a defrost function. Through accurate data judgment, the defrost time is greatly shortened, avoiding heat loss.
Multiple Safety Protections
Our YIERP factory implements various protections and tests on all our machines. The fault self-diagnosis rate is over 95%, and in case of abnormalities, the unit automatically shuts down and displays a fault code.
Remote Intelligent Control
Supports WiFi connection, allowing remote start/stop, temperature adjustment, mode switching, and energy consumption inquiry through a mobile app. Some models are compatible with voice control via Tmall Genie, Xiaodu, and other platforms.
Climate Adaptive Adjustment
Built-in climate databases for different regions automatically optimize operating parameters based on local temperature and humidity. In northern cold regions, low-temperature heating is enhanced, while in southern hot and humid regions, cooling and dehumidification are optimized.
Split heat pump units, formally known as split-type air source heat pump units, are one of the most mainstream applications in the field of heat pump technology. Their core design adopts a "separate structure of outdoor main unit + indoor heat exchange terminal," based on the thermodynamic principle of the reverse Carnot cycle. By consuming a small amount of electrical energy to drive the refrigerant cycle, they efficiently transfer low-grade heat from the air into high-grade heat. They are widely used for building heating, cooling, domestic hot water supply, and multi-energy coupling scenarios. Compared with integrated units (where all core components are housed in a single box), split units address traditional heat pump issues such as antifreeze, noise, energy efficiency, and installation adaptability through structural separation, making them the preferred heat pump solution for residential, commercial, and small to medium industrial applications.
