Commercial modular air-cooled heat pump unit

Unit operation principle diagram

An air-source heat pump is an energy transfer device.

1. The medium absorbs a large amount of free energy Q1 from the air in the evaporator;

2. Through the compressor's work, Q2, the medium is compressed into a high-temperature and high-pressure gas;

3. The medium exchanges heat energy Q3 through the heat exchanger to supply hot water or heating.

According to the law of conservation of energy:

Heat energy Q3 = Electrical energy Q2 + Air energy Q1

Modular Unit Technical Advantages

*Low-Temperature Gas Injection Enthalpy Enhancement Technology:

Low-pressure chamber enthalpy enhancement compressor with radial and axial flexible design, reinforced motor and scroll plate, compression ratio up to 14, meeting normal start-up and stable operation requirements in -30℃ environments;

*Independent Subcooling Technology:

 Two-stage subcooling improves heating capacity. Increased subcooling before the electronic expansion valve reduces refrigerant resistance loss, facilitates stable valve operation, and minimizes refrigerant flow noise;

*Intelligent Defrosting Technology:

The product design utilizes a four-way valve reversing defrosting method, along with three-state PID defrosting and reversing flow amplification technology. Through three-state detection—fin temperature probe, ambient temperature probe, and running time—the fin frost trend is linearly analyzed and judged, allowing for reasonable entry or exit from defrosting. It adapts to different ambient temperatures, achieving defrosting only when frost is present, with reasonable exit time and complete defrosting. This shortens defrosting time by 2-5 minutes, increasing the unit's operating efficiency by an average of 7% in low-temperature frosting conditions (including harsh conditions) in winter, and improving defrosting efficiency by [percentage missing]. 50%, saving electricity costs and energy.
