एचवीएसी लोड गणना

मूलभूत भवन डिजाइन निर्णयों और एक परिचालन भवन के बीच एक मजबूत पुल प्रदान करने के लिए हीटिंग और कूलिंग भार की सटीक गणना आवश्यक है। यदि भार को काफी हद तक कम आंका गया है, तो रहने वालों और उपयोगकर्ताओं को गर्मी या ठंड लगने की संभावना होगी। यदि भार को काफी हद तक बढ़ा दिया गया है, तो उपकरण बड़े आकार के हो जाएंगे (आमतौर पर पैसे की बर्बादी, दक्षता कम करना, ऊर्जा की खपत में वृद्धि और अक्सर आराम को खतरे में डालना)।

एयर चेंज सीएफएम कैलकुलेटर

The rate at which air is exchanged (in the premises) represents another method of measuring ventilation capacity & effectiveness. Air exchange rate is typically expressed in Air Changes per Hour – “ACH”. Air changes per hour can be estimated by determining the total air supplied to, and removed from, the premises “total air exchange” or the outdoor (fresh) air supplied to, and removed from, the premises “outdoor air exchange”. We invite you to experience how this calculator can transform your workflow. Whether you’re specifying a new system, troubleshooting an existing installation, or teaching the next generation of HVAC professionals, this tool was built with your needs in mind.
