Central HVAC and Air Conditioning Systems with Air - Water Air Conditioners

Central HVAC and Air Conditioning Systems with Air - Water Air Conditioners can be used in any building whether it is a commercial building or homebuilding as they can be comfortably combined with underfloor heating and cooling.
Especially can be used in buildings where large quantities of fresh air are required (large restaurants and cafes, entertainment centers, theaters, cinemas, hospitals, indoor stadiums and gyms, amphitheaters, bars ) are really ideal and are essentially the only way to cool and heat such spaces, as they are the only ones that can manage any amount of fresh air, while achieving fully controlled conditions of temperature, humidity and purity.

Central HVAC and Air Conditioning Systems with Air - Water Air Conditioners in order to achieve the necessary cooling-heating conditions in the air-conditioned spaces, cold or hot water and treated air are provided through central installations. The treated air supply has the ability to deal with either only the ventilation cooling or thermal loads of space or to undertake the treatment of some cooling or thermal loads, or even to undertake to fully manage all the cooling or thermal loads of the space.

Central HVAC and Air Conditioning Systems with Air - Water Air Conditioners - are divided into two main categories :

Systems with fan coils unit or water terminal air conditioning units (Concealed Ceiling Units or cassette type) either independently or combined with local or central Air Handling Units.

Systems with local or central Air Handling Unit which fully manage the cooling and thermal loads

Ιn these systems the production of cold or hot water can be done either through an air-cooled heat pump or through a heating boiler and an air-cooled or water-cooled water chiller.

Air-to-water systems can also be operated through other devices that utilize renewable energy sources, either autonomously or auxiliary (hybrid systems). Such are the central solar systems, geothermal, cold water or ice storage systems, steam-water plate exchangers, water-cooled condensers of other refrigeration systems that may exist and many other combinations through which excellent energy savings can be achieved and very low operating costs.

Industrial HVAC and Air Conditioning Systems

Industrial HVAC and Air Conditioning Systems mainly concern spaces and activities mainly in the food and medicine sectors and aim at achieving the specific conditions cooling, ventilation but possibly also heating for these spaces

Industrial HVAC and Air Conditioning Systems can be either systems with air-cooled or water-cooled water or glycol chillers combined with Air Handling Units and metallic air ducts or water-glycol refrigeration air-coolers and fabric air ducts or direct expansion refrigeration systems with air-cooled condensing units combined with refrigeration air-coolers and fabric air ducts

The choice of system depends mainly on the specific operating requirements of each space and secondarily on factors related to the space available and the configuration of each building. Industrial air conditioning systems usually include ventilation systems with which they are integrated installations HVAC Systems

Industrial HVAC and Air Conditioning Systems are also Central HVAC and Air Conditioning Systems with even more increased requirements.

Central HVAC and Air Conditioning Systems VRV or VRF

Central HVAC and Air Conditioning Systems VRV or VRF are ideal for medium-sized commercial buildings (shop, offices, hotel) as well as for large homes - villas).

Central HVAC and Air Conditioning Systems VRV or VRF consist of an outdoor unit (air- to air heat pump) and several indoor units placed in the areas we want to air condition and all connected to the same outdoor unit, through a network of pipes in which refrigerant circulates.

Indoor units can be either Concealed Ceiling Units, Ceiling suspended unit, Ceiling Mounted Cassettes, wall or floor units, or Concealed Ceiling Units of 100% fresh air up to 1000 m3 / h.

The outdoor unit has full inverter compressors that ensure extremely low power consumption even in partial load conditions with very low demand (The outdoor unit consumes as much energy as the indoor units require even if only one of them is running). Inverter compressors have suitable sensors that can detect low load demand and by acting on the compressor to change its operating frequency and adjust its efficiency to the required load, achieving maximum energy savings.

The vrv-vrf systems ensure complete autonomy per property and per space and consume energy only for the spaces that we want to heat or air condition. They are systems of the highest technological level and provide excellent conditions of temperature and relative humidity.

In particular, vrv-vrf type heat recovery systems have the ability to provide cooling, heating and hot water production through a special heat exchanger, saving huge amounts of energy, since their efficiency factor (COP) can reach during the summer months even at 10, which means that for every KW of electrical energy it consumes, heating energy delivers up to 10 KW in cooling.

There are many combinations and alternatives that can be proposed, designed and manufactured by Anadrasi, adapting a vrv-vrf system to the real needs and requirements of the building and ensuring a high quality Hvac - Air Conditioning System (heating - cooling - hot water) which at the same time will consume minimal energy

Semi-Central Air Conditioning Installations with Multi type Air Conditioners

Semi-Central Air Conditioning Systems with Multi type Air Conditioners are ideal for homes and small sized commercial buildings (shops, office buildings, small hotels, small restaurants, small cafes, doctor's offices, hairdressers, etc.)

The outdoor unit of the multi-type air conditioners has a full inverter compressor as well as suitable sensors that can detect low load demand and by acting on the compressor change its operating frequency and adjust its efficiency to the required load, achieving maximum energy savings.

Indoor units can be either Concealed Ceiling Units, Ceiling suspended unit, Ceiling Mounted Cassettes, wall or floor units.

Semi-Central Air Conditioning Installations with Air Duct Air Conditioners

Semi-Central Air Conditioning Systems with Air Duct Air Conditioners are divided into two main categories. In split type systems and package (rooftop) type systems. Semi-Central Air Conditioning Installations with Air Duct Air Conditioner are ideal for small sized commercial buildings (shops, office buildings, small hotels, small restaurants, small cafes, doctor's offices, hairdressers, etc.)

Semi-central air conditioning systems with duct type split air conditioners consist of one or more autonomous outdoor units (air to air heat pumps) and the corresponding indoor units, suitable for installation in a suspended ceiling. The air supplied by them, which is distributed in the space through air ducts and air diffusers, has the ability to deal with all the thermal or cooling loads of space as well as ventilation thermal or cooling loads at a rate of about 10-20% of the total air supply of each indoor unit.

The outdoor unit has a full inverter compressor as well as suitable sensors that can detect low load demand and by acting on the compressor change its operating frequency and adjust its efficiency to the required load, achieving maximum energy savings.

Semi-central air conditioning systems with duct package type air conditioners (rooftop) consist of one or more air conditioning units which incorporate both the condensing unit that produces cooling or thermal energy and the fan-element unit through which the air is supplied to the spaces. Package type units are usually installed outdoors in the building and the air which is brought to the spaces as well as the air which is exhausted from them is directed to the air conditioning units through air ducts and air diffusers.
