加熱器使用注意事項
1.PTC加熱器的功率受外部環境影響很大，理想的測試方法是在標準工況下安裝在整機中進行。通常為便于雙方檢驗確認，實際操作時，是以在整機中確認的封樣件來調整模擬風道的相關參數后測試的。測試時環境溫度一般保持在20～25℃左右。
2.PTC加熱器在工作時有熱膨脹現象，故在結構設計時應考慮加熱器周圍留有一定間隙（5mm以上）；
3.若選用表面帶電型加熱器，在設計時還應考慮防觸電措施及蒸發器結霜時的安全間距，確保沒有人體、金屬物和霜層觸及的可能。選用表面絕緣型加熱器則較為安全；
4.加熱器裝接三相供電時，應采用Y型連接，且中性點必須接零線，避免因三相不平衡造成某路加熱器端電壓過高的故障隱患

PTC加熱器特性
PTC加熱器采用PTCR熱敏陶瓷元件，由若干單片組合后與波紋散熱鋁條經高溫膠粘結組成，具有熱阻小、換熱效率高的優點。它的較大特點在于其安全性，即遇風機故障堵轉時，PTC加熱器因得不到充分散熱，功率會自動急劇下降，此時加熱器的表面溫度維持限定在居里溫度左右（一般為220℃），從而不致產生電熱管類加熱器表面的“發紅”現象，排除了發生事故的隱患。
本公司MZFR系列加熱器目前已廣泛應用于家用空調器的熱泵輔助加熱、商用中央空調及加熱類小家電產品。

PTC Heaters
The PTC heater is composed of several PTCR ceramic components adhered to wave Al tube by high temperature. It features in low thermal resistance and high coefficient of heat transmission.Besides, when the fan blocked,power of PTC heater would drop down sharply due to insufficient dissipation.Meanwhile surface temperature of heater would remain at the level of curie temperature,which is usually 220℃so that potential accident would be eliminated.
At present, our MZFR series have been extensively applied in home aircondition,commercial aircondition as well as household heating appliances.
