USUAL QUESTIONS & ANSWERS

1. It is suitable for under-floor heating for your health?
The under-floor heating system is said to cause problems for those suffering from varicose veins or circulation. Studies have been done by international health organizations have demonstrated that the human body welcoming floor temperature of 20 ° C up to 33 ° C and bothered when the temperature is below 17 ° C or above 36 ° C. In a well configured installation of floor heating, the average water temperature in the pipes is 45 ° C, while the floor temperature ranges between 25 ° C and 28 ° C. If you think about the human body temperature is 36,6 ° C, toteeinai unlikely to understand that burning the floor. On the other hand, the advantages of the floor in terms of health are many: the low temperature of the water flow and warms the air more than 25 ° C, so it loses its moisture.

2. Is under-floor cheaper than what the radiator?

The construction cost of the floor is more expensive, but the price includes thermompeton and insulating layer, which omitted the cost of the radiator. The heating is 35% cheaper to operate than a conventional heating. This is explained because the temperature of the water inlet pipes is 45 ° C, while heating 80 ° C. If you consider that for every 1 ° C reduction in inlet temperature, we have fuel economy 3%, then the perceived benefit to maintain the water temperature operation as low as possible.

3. How exactly it works under-floor heating?

The under-floor heating water from the boiler through a three way or four-electrode valve, which depending on outside temperature (controlled with an external sensor) and temperature (controlled by thermostat) allows water to pass appropriate temperature. Meaning if outside temperature is For example 0 0C automatically pass valve and water temperature eg 45 0C, but if you're outside temperature is 15 0C for example, the valve automatically closes and passes such as water temperature 30 0C To floor acts as a radiator. Due to the specific recommendation of thermompeton, all radiate the heat indoors. Still, the dense screed pipes near outside walls holding back the cold, while the lighter laying in the interior of the rooms allows the transmission of lower thermal loads.

4. It can work the floor with other systems?

The heating can work with radiators levitostasio. To a common body of water driven by pump directly into the body, while the water pump from another floor passes a three way or four-electrode valve that adjusts the temperature.

5. What would happen if a drill pipe in floor heating?

The potential to cause some damage is minimal, since the tubes are made of plastic so as not to break the curvature of the systodiastoles and not eroded or internally or externally. However, in the unlikely event that punctured a pipe, there is adequate equipment that allows us to locate and repair the damage at the point just manifested. Therefore, there needs to be dismantled over the floor, only an area of less than one square meter.

6. They can use other energy sources in under-floor heating, other than oil?

The heating can be powered by any energy source. Apart from oil or gas boilers, under floor can be covered with alternative heat sources such as solar energy, heat, electricity, etc.

USUAL QUESTIONS & ANSWERS                                                                          
 
 
1. What is Technology Inverter?
The technology inverter, analog power control of the air conditioner. Modifying the frequency of power supply or the complaint, ensuring a smooth linear change of the speed of the compressor is the heart of your airconditioner.
This allows the alignment of the cold and thermal power to the individual required actual operating conditions. When the temperature of conditioned space is very different from the preset temperature, the air conditioner operates with maximum effect, ensuring the rapid achievement of the desired temperature.
Once the desired temperature in the conditioned space, the compressor regulates precisely the power to maintain the desired temperature.

2. How do the units constant speed
Constant speed units are units of fixed income and have compressors start or stop operation, depending on the temperature of conditioned space. When the thermostat of the indoor unit ultimately the operation of the compressor based on the desired temperature. It is essential that the units have a constant speed high-precision thermostat to minimize the fluctuation of temperature in air-conditioned space.

3. The units Inverter technology is more economical to operate
Thanks to the Inverter technology the efficiency of air conditioning units is significantly higher during the operation at full load and part load. Since the air conditioning units operate more than 80% of their time at part load, the higher efficiency units with technology inverter, lead to significant energy savings up to 30 ~ 40% of annual energy consumption compared to fixed speed units corresponding power.

4. What is the energy class of units?
The Energy Class is the classification of air conditioning units where power consumption. EU legislation requires all new air conditioners have a label with the "Energy Label" device. The classification is made in seven different categories, A to G, with A indicating the most efficient unit and G the least efficient, which should always be to avoid using it.
The choice of an air conditioner with high energy class is usually equipped with the technology of engines and compressors Inverter providing comfort and operating economy.
Please note that the choice of a unit with high efficiency A + and the use of inverter technology can bring savings in operating costs up 50% compared with a conventional constant speed drive and Power Class B.
The COP for domestic air conditioners must be up to 4.37 with average of 3.96 and EER up to 4.18 and average 3.55.

5. How is the quality of air in conditioned space?
Filtering and cleaning air. The effective control of air quality facilities, not only depends on the filtration of indoor air. Especially in the air recirculation units such as autonomous air conditioning units, control of indoor air quality should be passed through several stages and additional features such as pre-cleaning, basic cleaning and removal of microscopic particles, viruses, bacteria and allergens from the air .
 
6. What are the ecological refrigerants and what are their differences?
The refrigerants used in residential air conditioning applications should be environmentally friendly and do not affect the ozone layer in the atmosphere. The main "green" refrigerants used in residential air conditioning are:
HFC 407c: This blend of three refrigerants of R32, R125 and R134a.Parousiazei but many disadvantages, because it is zeotropiko (the phase shift of each component is achieved at different temperatures and has high thermal drift). The theoretical efficiency (COP) compared to other refrigerants is low on this and used lower-cost units. (Economical solution with lower energy class)
HFC 410a: This blend of two refrigerants of R32 and R125. It works on 50% higher pressure than the R407c. Behaves like a homogeneous refrigerant, and the temperature difference which is achieved by changing the phase between two components is negligible (<0,2 K). An additional advantage is the higher energy content per unit volume and better heat transfer rate.

7. What size air conditioner is right for my space?
H choosing the appropriate size of an air conditioner in an area depends on the use and internal conditions of space, insulation and structural elements of space (windows, roof, etc.), lighting, ventilation, number of people t . l.p. for residential relatively good insulation is a simple rule for calculating the required cooling load is 1 / 2 of surface area in kBtu / h. That is a 18m2 space required 18 / 2 = 9 kBtu / h (or 9000 Btu / h).

8. What Ways are existing for cooling and heating?
Distinguish their cooling following ways:
  • Cooling refrigerant freon (VRV inverter, split heat pumps)
  • Cooling water (fan coil)
  • Cooling air (vents)
9. What the difference in cooling-air?
The difference in air-cooling is that apart from the cool places we simultaneously treated air to control humidity and purity of this. That is an air conditioning gives us control of temperature, humidity and air quality in areas of building and installing a cooling only achieve temperature control of the premises. Special air-conditioning use "air conditioning air handling units" which include: a) identification of water (hot and cold), b) element humidifier, c) heat exchanger air / air energy savings from the discharged air to fresh air, d) air filters and e) supply fan and return air.
