This document discusses principles and methods for estimating cooling loads on buildings. It covers heat transfer mechanisms like conduction, convection and radiation. It explains factors that affect human comfort and methods to estimate different components of a cooling load, including conduction through surfaces, solar heat gain through windows, internal heat gains from occupants, lights, equipment and infiltration. An example calculation is provided to estimate the sensible and latent cooling loads on an office space from these various components. The purpose is to understand and quantify all sources of heat gain on a building to properly size air conditioning equipment.Heating and-air-conditioning-of-building-faber-and-kell-chapter-14-air-condit...

The document discusses building ventilation and air conditioning. It defines ventilation as supplying fresh air into a room and removing stale air. Ventilation is necessary to remove harmful particles, odors, and gases. There are two types of ventilation - natural/passive using windows and doors, and mechanical using fans. Air conditioning involves controlling temperature, humidity, and air distribution for occupant comfort and industrial processes. The principles of comfort air conditioning include maintaining temperatures between 20-23属C, controlling air velocity and humidity levels, and accounting for seasonal differences.Building services.pptx

Building services include systems that make occupants comfortable, functional, efficient and safe, such as ventilation, air conditioning, water supply, drainage, plumbing and electrification. Ventilation involves supplying fresh air into a building and removing stale air. It is necessary to remove stale air, prevent concentration of odors and bacteria, and prevent buildup of flammable gases. Ventilation can be natural via openings, or mechanical using fans. Proper plumbing systems include water distribution, drainage, and sanitation to provide potable water and safely remove wastewater. Air conditioning cools, dehumidifies, filters and circulates air to maintain occupant health and comfort.HVAC introduction

Central air conditioning systems have several key components:
1) A central plant room contains the chiller, compressor, condenser, and other equipment that cools water which is circulated throughout the building.
2) Air handling unit rooms include air handling units that blow cooled air into ductwork leading to individual rooms.
3) Air conditioned rooms receive cooled supply air through ceiling diffusers and return warm air to the air handling units through floor diffusers.
4) A cooling tower cools the water used by the central chiller and condenser before it is recirculated.BUILDING-SERVICE-HVAC//.. building services

Air conditioning involves simultaneously controlling the temperature, humidity, cleanliness, and distribution of air. It conditions and transports air to a conditioned space while maintaining predetermined environmental limits for occupant comfort. There are two main types of air conditioning systems: comfort systems that provide a comfortable indoor environment, and process systems that control the environment for manufacturing or other processes. Common comfort applications include commercial buildings, residences, healthcare facilities, and transportation. Process systems are used in textile mills, clean rooms, precision manufacturing, pharmaceutical facilities, and refrigerated storage. Refrigeration methods include non-cyclic techniques using ice or dry ice and cyclic vapor-compression or vapor-absorption refrigeration cycles.CHAP 4 HVAC.pdf

Remote monitoring has been implemented in many areas. This paper
introduces its specific application to air-conditioning plant control and
monitoring using PIC Microcontroller. Remote monitoring and intelligent
maintenance is one of the most important criteria for maximizing production
and process plant availability. Initially switching and monitoring were done
through manually and the control switches and level monitoring unit were
placed at separate places. Due to this, we cannot monitor all units at a time. In
our proposed system, remote switching and monitoring is done in the control
room itself. Majority of industries use distributed control system for high
reliability, improve response time, improved operator interface to plant,
improved accessibility of plant data.Central Ac Powerpoint
