HVAC and BMS are two different services which are usually connected with each other.

HVAC is mainly concerned with maintaining the comfort environment in terms of temperature and humidity while BMS is the management system which can either monitor or control HVAC and many other services like Electrical, fire fighting and plumbing services through a computer interface or some other automatic mean.

Through BMS many service parameters are visible on computer like what is the temperature in which room or what is the level of water tank or which pump is not working having fault alarm etc. But BMS can run with lot of sensors and actuators without which BMS cannot run.

A Building Management System and a Heat, Ventilation and Air Conditioning system are systems that set and control the environment in buildings.
They control temperature, pressure, humidity, and ventilation rates.
They comprise hardware like valves and other mechanical devices, and software to control opening and closing of the mechanical devices to keep the measured values inside the set (acceptable) values.
The set values are important to keep cleanrooms as clean as they should, and not so important for offices.
For validation purposes it is far easier to validate the systems if the mechanical parts are distinct entities.
Then you can validate the high risk areas and not bother with the low risk areas

HVAC SYSTEM IS HEATING, VENTILATION & AIR CONDITIONING AND IT IS A MECHANICAL SYSTEM WHICH DESIGNED IN BUILDINGS AND MAY BE IT IS DESIGNED CENTRAL WHICH USE DUCTS , DIFUSSERS AND GRILLS OR BE INDIVIDUAL UNITS LIKE SPLITS AND WINDOS UNITS

BUT BMS IS A MONITORING AND CONTROL NOT MONITORING ONLY BECAUSE THIS JOB IS ABOUT SCADA AND ITS JOB IS CONTROLLING ALL SYSTEMS IN BUILDING LIKE FIRE ALARM , LIGHTING , HVAC ,CCTV,.....etc

NOW THERE IS A SYSTEM LIKE BMS BUT IS BETTER WHICH IS EIB SYSTEM

HVAC:

Heating, Ventilation and Air Conditioning, deals with system of creating comfortable conditions in the building premises by increasing or decreasing the temperature through Mechanical Equipment and other accessories.

 

BMS:

Building Management System which deals with control, parametric measurement and central control of all building facilities through one central station.

HVAC (Heating Ventilation & Air Conditioning) system is one of the mechanical building services in a building whereas BMS (Building Management System) is an instrumentation system. HVAC system address the air quality & its movement for confined spaces & zones throughout the building whereas BMS addresses the monitoring & controlling of various parameters of building services including HVAC for efficient functioning.

BMS stands for Building Management System whereas HVAC stands for Heating Ventilation and Air Conditioning.
HVAC system is responsible for providing desired parameters of temperature and humidity.
Normally now a days, HVAC system is installed with B.M.S.
for energy efficiency.
BMS monitors different parameters with help of different sensors.
These parameters are compared with set parameters and accordingly actions are taken to achieve the set parameters.
It works in closed loop.
BMS also provides a computer interface where temperature , humidity and air flow for monitoring and these can also be adjusted there by setting values there-in.
