1. The world is heating up rapidly, the summer in European and African countries is becoming unbearable year after year. In Europe there is a law that prohibits the installation of air conditioning motors (condensers) on the walls/windows of buildings and houses. At the same time, most of the electrical infrastructure in homes is based on a small electrical infrastructure that cannot meet the electricity supply for a home air conditioning system.

2. In hotels containing at least 50 rooms, the average size of a room is 20 square meters. In each room, a cooling unit with a power of 2 horsepower is installed. This means a total consumption of 100 horsepower.

The size of the cooling engine installed on the roof (chiller) is calculated according to the number of cooling units and their joint consumption. For example: a 100 hp engine consists of 2 40 hp engines and one 20 hp engine.

In addition, there are pumps whose function is to flow water through dedicated piping to each floor of the hotel, thus recycling the water cooling on each floor and transferring it when necessary to the cooling units in the rooms.

These pumps consume expensive electricity and they will be operated on the floor even if only one or two rooms will operate an air conditioner.

This means a complete imbalance in resources, waste of electricity and high costs far beyond what is required.
