Window Air Conditioner used as the Heat Pump

In the summer season the evaporator acts as the cooling coil. The air flows over it, gets cooled and it is supplied to the room for producing the cooling effect. The heat absorbed by the air in the room is thrown to the external atmosphere via the condenser. This is the normal working of the window air conditioner.

Importance of the Heat Load Calculations - Part 2

The importance of the heat load calculations can be understood from the fact that right from the designing of the building itself, the HVAC designer works closely with the building architect to making recommendations for the locations of the various air-conditioning systems of suitable sizes.

Importance of the Heat Load Calculations - Part 1

The heat load calculations play vital role in all aspects of the air-conditioning systems of large buildings. It affects the size, type, and location of the airconditioner systems.

What is HVAC Heat Load Calculations? Part 4: Process of Heat Load Calculations - 2

After surveying the building, the actual process of the heat load calculations will start. The actual heat load calculations can be carried out manually or using HVAC software.

Process of Heat Load Calculations - Part 1: What is HVAC Heat Load Calculations? Part 3

Having seen what heat load calculations is, let us see the process of heat load calculations done by HVAC designer. The heat load calculations are a highly specialized, time consuming and complicated task of the HVAC designers.

Why We Need Air-Conditioners? Part 1

The use of air conditioners, popularly known as AC, has become almost compulsory in number of homes and houses. In fact there are number of people who just can’t live without AC, they will need AC in their room, office, car, theater and almost everywhere. Why is it that we need AC?

Coefficient of Performance of the Heat Pumps

The coefficient of performance, also called as the COP, of the heat pump is defined as the ratio of the desired effect from the heat pump to the power consumed by the heat pump.

Various Components of the Heat Pump: Part 4

The next parts of the heats pumps are expansion valve and evaporator. The expansion valve is the pressure reducing devise.In heat pumps the evaporators is located outside the room and exposed to the atmosphere which is at very low temperature.

Various Components of the Heat Pump - Part 3

The next important part of the heat pump is condenser. The function of the heat pump is to heat the room, and it is the condenser that produces the heating effect inside the room.

What is Heat Pump?

Heat pump is the devise which is used to heat the room room winter seasons. All the components of heat pump are exactly same as the air conditioner and refrigerator, the only difference is that they work in reverse direction.
