We are a family with small children, living in an apartment building. What system should we install?
Since the home in this case, is usually in full occupancy, we recommend a mini-central unit that will cool the entire home, the price is reasonable, a uniform temperature will be obtained throughout the apartment, and the use will meet the requirements.
We are a family with older children, which are not always at home (son is in the army and daughter in the university). What system should we install?
In this case, since the home is not in full occupancy, we recommend that the apartment will be divided to a number of living units, matching your living space. For example, install a small split AC unit in your bedroom, and a mini-central unit for the rest of the home. The bedroom AC will serve you when you stay in your bedroom, and the mini-central unit will be turned on when the home is in full occupancy, so you can save ongoingly. (In such a case we should verify there is sufficient room for two external condensation units).
We are an established family with small children building a private home. What system is recommended for us to be installed?
There are two options here:
- A split AC in your bedroom and central mini units in the other areas (children’s rooms, living room, basement) are recommended. The cost of such project is about NIS 140 per square meter + VAT.
- A system with a variable gas volume – the cost in this case is about 500 NIS per square meter + VAT, but there built in savings in the cost of the electricity connection to the home and ongoing savings in electricity bills, which can pay for itself in about 5-6 years (relative to the difference between this system and a central mini.)
We are a middle-class family + with older children who are not always at home – building a private home. Which system should we install?
Since the home is not in full occupancy, and assuming there is enough space in the roof (attic), it is recommended that you install split AC in each child’s room, and a mini-central AC unit for the large spaces such as Living room, kitchen, or basement. So, you can save electricity and turn the AC only in the occupied spaces.
We are an established family in the process of building a luxury private home. Money is not an issue! We want the best and most advance Ac system. What will you recommend?
There are two options for this type of home:
- Chiller system (manufactured by Carrier or Train or Electra or Kalimonte or MTE or equivalent).
- variable gas volume system (VRF) from Mitsubishi Odaikin or equivalent).
The chiller system is cheaper to install and more expensive in the running cost (maintenance and electricity)
A variable gas volume system is more expensive to install, but significantly more efficient and economical in electricity and maintenance.
A variable gas volume (VRF) system is recommended.
In such a case, a senior consulting engineer must be consulted and planned to adapt the system to the special architectural design and coordinate it with all other home systems (electricity, drainage, construction, acoustics, etc.)
We are a low-income family, we cannot afford an air conditioning system. What can we do to get some relief from the heat load?
The least expensive option is ventilators. However, you should note that the ventilator aeration is only effective when air is thrown directly on the body skin! as sweat evaporation drives the colling process, it is recommended to install fans close to you, which are relatively inexpensive.
Ventilation where the air is not thrown directly on the body – is not effective!
We are young and broken, we cannot even afford a ventilator. What can we do to get some relief from the heat load?
First, close the windows and shutters and prevent from sun rays to enter your apartment, then, as floor temperature is cooler by a few degrees from the room temperature, it is recommended that you take off your clothes and lay down on bedsheets you spread on the floor.
