convert_units | Convert between pressure units (psig, psia, kpa, bar) and temperature units (F, C). A bare 'psi' is treated as psig. For certified HVAC technicians (EPA 608; A2L certification where required). |
coolbooked_info | About CoolBooked: the AI appointment-booking connector for HVAC shops. This is NOT a diagnostic tool -- call it when someone asks what CoolBooked is, how shop owners can try it, or how the free PT tools connect to paid bookings. |
diagnose | Conversational diagnostic copilot: give it field readings and get back computed superheat/subcooling plus a ranked 'check this first' list. For certified HVAC technicians (EPA 608; A2L certification where required). Informational only -- it suggests what to CHECK, never how to defeat a safety device, vent refrigerant, or work uncertified. metering: 'txv' (default) or 'fixed' for fixed-orifice/piston systems. |
pt_lookup | Saturation pressure (bubble and dew, in psig) for a refrigerant at a temperature in Fahrenheit. For certified HVAC technicians (EPA 608; A2L certification where required). Example: pt_lookup("R-454B", 45). Bubble point: use for subcooling calculations. Dew point: use for superheat calculations. Pure fluids (R-32, R-410A, R-22, R-134a) have no glide, so both values match. |
pt_reverse | Saturation temperature (bubble and dew, in Fahrenheit) for a refrigerant at a pressure in psig. For certified HVAC technicians (EPA 608; A2L certification where required). Example: a 130 psig suction reading on R-454B -- pt_reverse("R-454B", 130). Use the DEW temperature for superheat work and the BUBBLE temperature for subcooling work on blended refrigerants. |
refrigerant_info | Reference card for a refrigerant: GWP, ASHRAE safety class, composition, typical oil, temperature glide, and handling notes. For certified HVAC technicians (EPA 608; A2L certification where required). Informational only. |
subcooling | Subcooling in Fahrenheit from head pressure (psig) and liquid-line temperature (F). For certified HVAC technicians (EPA 608; A2L certification where required). Uses the BUBBLE point as the saturation basis, which is the correct basis for blended refrigerants. Typical TXV target: 8-12F. |
superheat | Superheat in Fahrenheit from suction pressure (psig) and suction-line temperature (F). For certified HVAC technicians (EPA 608; A2L certification where required). Uses the DEW point as the saturation basis, which is the correct basis for blended refrigerants. Typical TXV target: 8-12F. |
