One device, many jobs Air-to-air heat recovery is applied across very different buildings, and the “best” exchanger depends on what each building values most: air purity, uptime, moisture control, or simply first cost. Below are three common sectors and the logic that drives their choice. Hospitals Air quality is non-negotiable. Fresh-air volumes are huge and […]
板式 vs 转轮 vs 热管：如何选换热器
Choosing the right air-to-air heat exchanger depends on airflow, temperature, humidity, installation space, and contamination risk. This guide compares the three most common technologies. Quick Comparison Feature Plate Exchanger Rotary Wheel Heat Pipe Efficiency High (70–85 %) High (75–85 %) Moderate (50–70 %) Moving parts None Motor/bearings None Cross-contamination Very low Low with purge Zero […]
热泵选型计算
A correct heat pump selection calculation prevents both undersizing (poor performance) and oversizing (short cycling and wasted capital). The method below applies to space heating, domestic hot water, and process heat recovery alike. Step 1 — Define the Load Start from the peak heating or cooling load in kW. For recovery duties, size to the […]
热管换热器选型：被动回收占优的情形
What a heat pipe is A heat pipe is a sealed tube with a working fluid that transfers heat by evaporation and condensation – no moving parts, no power, no cross-flow. In HVAC, banks of heat pipes sit in the airstream to pre-cool (or pre-heat) incoming air using the exhaust stream. It is the most […]
