Engine house equipment in buildings includes mechanical devices and electrical controllers and facilities necessary for cooling and heating the building, which exist in one space because their control becomes easier.

The location of this equipment is the engine room, and gathering the necessary facilities in one place makes the repair process of the engine room easier.

The engine room is considered the turning point of a building, in the past years, the central engine room was common in buildings, now due to the high cost of fuel, this separate system is installed in each unit.

Engine houses are used for building air conditioning and heating, and according to different methods of air conditioning and heating systems, there are different equipments in engine houses, such as boilers, burners, chillers, etc.

Engine room equipment includes deaerator, boiler or boiler, chiller, water pump, burner and expansion source, each of which has a specific function.

Central engine room equipment
The oxygen deaerator separates water from water, which is one of the main causes of corrosion in pipelines, boilers and pumps, and pre-heats water before entering the boiler.

Boilers in central heating engine room equipment are one of the heat generators in the engine room and are divided into three types of hot water, hot water and steam depending on the type of consumption.

The water in these boilers can have negative temperatures and turn into warm, hot water or steam. Boilers are cast iron and steel in terms of material and construction.

Chiller is another engine room equipment and has two compression and absorption models. Its compression model consumes more electricity, but the absorption model uses thermal energy, is quiet and vibration-free.

The number of moving parts of absorption chillers and its repair costs are less than those of compression chillers and it has an economic advantage.

In the past, the central engine room equipment was located in the lowest part of the building, but today, with chillers and mini chillers, these systems are installed on the roofs.

Building engine room equipment
The water pump in the engine house is the equipment of the building to transfer water by creating pressure. The water heated in the boiler is transported in pipelines using a pump.

According to the different conditions in which they are used, the pumps have different dimensions and capacities and are considered heat and cold distribution equipment in the engine room equipment.

The hot and cold water that is produced inside the engine house in the boiler or chiller passes through the transmission networks and reaches the cold and heat distribution devices.

Fan coils and air conditioners are examples of heat and cold distribution devices that perform air conditioning and are used for heating in winter and cooling in summer.

The fan coil is usually installed under the windows to distribute hot and cold air, but the air conditioner also controls the air humidity.

Heating engine room equipment
The burner is one of the important components in the heating engine room equipment, and the process of producing heat and heat in the boilers is done by the burner installed on the boiler.

In most cases, the fuel of the burners is gas or diesel, and the thermal energy needed by the boilers to heat or heat the water is provided by the burner.

The expansion source in the heating engine room equipment protects the pipes and prevents them from bursting due to volumetric expansion.

The expansion source transfers the water in the source to the system when the water in the system is low, and it is made in two types, open and closed.
