Degree Day API

salutare 3,467 Abbonati

Heating and cooling degree-day maths as an API, computed locally and deterministically. The daily endpoint computes the heating degree days, HDD = max(0, base − mean), and the cooling degree days, CDD = max(0, mean − base), for a single day from a base temperature and the daily mean — or the minimum and maximum, since the mean is taken as their average. The period endpoint sums the degree days over a list of daily temperatures (means or min/max pairs), returning the total HDD and CDD, the count of heating and cooling days and the average temperature — the standard way to characterise a heating or cooling season. The energy endpoint turns degree days into an energy estimate: the heat delivered is UA·DD·24/1000 kWh from the building heat-loss coefficient, the fuel or electricity input is that divided by the boiler efficiency (or a heat-pump COP), and — with an energy price — the cost. Everything is computed locally and deterministically, so it is instant and private. Ideal for building-energy, HVAC and facilities tools, heating-bill and fuel-budget estimation, weather-normalisation and energy-benchmarking apps, and engineering education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is degree-day demand estimation; for U-value and heat-loss fabric calculations use a U-value API.

API de calculadora de BTU para HVAC

Matemáticas de dimensionamiento de HVAC como API, calculadas local y determinísticamente a partir de factores estándar de regla general. El endpoint de refrigeración estima la carga del aire acondicionado para una habitación — en BTU por hora, toneladas de refrigeración y kilovatios — a partir del área del piso (en pies cuadrados o metros, o largo × ancho) usando una línea base de aproximadamente 20 BTU/h por pie cuadrado, con ajustes por el número de ocupantes, una cocina, exposición solar y altura del techo. El endpoint de calefacción estima la carga de calefacción a partir del área y una zona climática (templada a muy fría) o un BTU personalizado por pie cuadrado. El endpoint de conversión convierte entre BTU por hora, toneladas de refrigeración, kilovatios y vatios (una tonelada = 12,000 BTU/h ≈ 3.517 kW). Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Estas son estimaciones de regla general al estilo EnergyStar — se recomienda un cálculo de carga Manual J adecuado que tenga en cuenta el aislamiento, las ventanas y el clima local para una instalación real. Ideal para herramientas de HVAC y mejoras del hogar, guías de dimensionamiento de aires acondicionados y calefactores, aplicaciones de hogar inteligente y energía, y cotizaciones para contratistas. Cálculo local puro — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es dimensionamiento de HVAC; para el costo de funcionamiento de electrodomésticos, use una API de costo de energía.

Firewood Calculator API

Firewood maths as an API, computed locally and deterministically. The volume endpoint turns a wood-stack's length, height and depth (in feet or metres) into its volume in cubic feet and cubic metres, full cords, face cords and steres — a full cord being 128 cubic feet (a 4×4×8 ft stack) and a face cord being an 8×4 ft stack by the piece (log) length. The convert endpoint converts a quantity between cords, face cords, steres, cubic metres and cubic feet, using the piece length for the face-cord relationship. The heat endpoint estimates the heating value of a number of cords by wood species — returning the millions of BTU and the equivalent gallons of heating oil, therms of natural gas and kilowatt-hours — from a built-in table of typical seasoned-wood values (oak, hickory, maple, ash, birch, pine and more) or a custom figure. Everything is computed locally and deterministically, so it is instant and private. Heat values are typical seasoned figures (around 20% moisture) and vary with species, dryness and stove efficiency. Ideal for firewood sellers and delivery tools, heating and homestead apps, and forestry and woodlot calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is firewood volume and energy; for general volume or unit conversion use a unit-conversion API.

Heatsink Thermal API

Heatsink and thermal-resistance maths for electronics as an API, computed locally and deterministically. The junction endpoint computes the junction temperature of a component from its power dissipation, the ambient temperature and the thermal-resistance chain, Tj = Ta + P·(Rθjc + Rθcs + Rθsa) — junction-to-case, case-to-sink (the interface material) and sink-to-ambient — and also reports the case and sink temperatures and, given a maximum junction temperature, the headroom. The required endpoint solves the largest heatsink thermal resistance you may use to stay under a junction limit, Rθsa = (Tj_max − Ta)/P − Rθjc − Rθcs, and flags when no heatsink can do it. The power endpoint gives the maximum power a device can dissipate for a given thermal path, P = (Tj_max − Ta)/Rθtotal. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics, power-supply and PCB-design app developers, heatsink selection and thermal-budget tools, and engineering education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is conduction thermal-resistance; for convective Newton cooling use a cooling API.

Propane & LPG Tank API

Propane and LPG tank maths as an API, computed locally and deterministically — the usable-fill, energy and burn-time numbers a homeowner, RV-er, grill-master or HVAC tech works out at the tank. The tank endpoint turns a tank size into real numbers: liquid propane is 4.24 lb per gallon and holds 91,452 BTU per gallon (about 21,569 BTU per pound), so a 20 lb barbecue cylinder carries roughly 4.7 gallons and 431,000 BTU. It knows the two ways tanks are sized — a portable cylinder (20, 30, 40 lb) is rated by the propane weight it holds, while a bulk tank (100, 250, 500, 1000 gal) is filled to only 80 % of its water capacity to leave room for expansion, so a 500-gallon tank actually holds 400 gallons of propane and about 36.6 million BTU. The burntime endpoint divides that energy by an appliance’s BTU-per-hour input rating to give run time: that same 20 lb cylinder runs a 30,000 BTU/hr patio heater about 14 hours, and an optional hours-per-day turns it into days. The refill endpoint costs a fill from a price per gallon, gives the cost per 100,000 BTU so you can compare propane to natural gas or electricity, and — with an appliance rating — the running cost per hour. Everything is computed locally and deterministically, so it is instant and private. Ideal for home-energy, HVAC, RV, off-grid, grilling and outdoor-living app developers, fuel-cost and tank-monitor tools, and propane-delivery calculators. Pure local computation — no key, no third-party service, instant. US units. Live, nothing stored. 3 compute endpoints. For vehicle fuel economy or the ideal gas law use a different API.
