Definitions
- the invention relates to a heating and air conditioning installation, and a method installation of such an installation.
- the technical field of the invention is the heating and air conditioning of residential premises for residential, public or professional use.
- the invention is particularly applicable to premises equipped with a heating network central and an isolated air conditioning network or a multipurpose isolated network depending on the season to distribute hot water or cold water.
- water is used broadly, and obviously includes any fluid can be used for such networks, with or without additive such as antifreeze or like.
- Heating and air conditioning networks include at least one boiler and one water cooler individual or collective, such as a boiler, heat pump, reversible group, chiller, absorption machine ..., or all connection to a main heating or cooling network. These networks can also be linked to mixed production systems such as heat pumps, absorption systems ...
- the object of the present invention is to overcome these drawbacks by proposing an air conditioning and heating system allowing both air conditioning during air conditioning and radiant comfort during heated.
- Another object is to avoid noise pollution in heating mode by shutdown of the fan or by its inaudible slow ventilation operation.
- the object of the invention is also not to have to have systems condensate drain, which can optionally be reinjected into the cooling loop.
- the box further comprises a hot fluid exchanger arranged in series with respect to the radiator.
- the hot fluid circulation pipes are separate cold fluid circulation pipes, the heating network being independent of the cooling network.
- the circulation pipes are mixed between the hot fluid and cold fluid.
- the installation includes prohibition means comprising a two valve channels for regulating in heating mode the supply of hot fluid to the radiator, the two-way valve can be controlled by a thermostat.
- the installation also includes a two-way valve for regulating the cold fluid supply in cooling mode of the cold fluid exchanger at fins and therefore the cooling power dissipated at the exchanger at cold water fluid.
- the fan In air conditioning mode, the fan is on and has at least one speed of regulation of the power dissipated at the level of the fluid exchanger cold with fins.
- the fan In heating mode, the fan is either stopped, the ventilation of the exchanger with hot fluid with fins when the installation includes one being produced by natural convection, either in slow ventilation mode to obtain a higher thermal power.
- the installation includes, according to one embodiment, a pH maintaining regulator intended to avoid acidification of the heating network caused by the circulation of condensed water in the network.
- the installation comprises control means and means for connecting the air conditioning and heating device to a source energy such as the local electrical sector.
- the radiator is typically placed on the front or on the part upper case
- the installation includes an automatic summer / winter changeover means triggered according to the temperature of the network fluid.
- It may also include means for recovering condensates from the cold finned heat exchanger.
- FIG. 1 a central heating installation is shown an isolated hydraulic network allowing the transit of hot or cold water according to the season.
- a three-way valve 5 In heating mode, a three-way valve 5 enables the boiler 1 to be supplied service via a circulation pump 2. As a result, the network insulated 3 allows the hot water supply to the device designated below heating and air conditioning terminal 6. In the latter, a means prohibition such as a three-way valve 7 open in heating mode on a channel 8 allows the supply of a radiator 11 arranged on the front of the terminal heating and air conditioning 6, and a finned coil 12 arranged in series with the radiator 11.
- this battery is an example of a hot fluid exchanger intended to produce heat, other types of heat exchangers may be used.
- the tilting of the three-way valve 7 is obtained by means of a summer / winter changeover can be manual or automatic, such as thermostatic example as a function of the temperature of the water circulating in the network 3.
- the regulation of the dissipated thermal power at the terminal 6 is obtained by a two-way valve 10 controlled by a thermostat 18 depending on the difference between a setpoint and the room ambient temperature.
- the fan 15 is stopped, ventilation of the finned coil 12 being carried out by the phenomenon of natural convection, or in ventilation mode notably slow which, while remaining inaudible allows obtaining a much higher thermal power.
- the three-way valve 5 allows bypassing, that is to say bypass, the boiler 1 which is out of service, and supply a cooler of water 4 in service, via pump 2 still in service.
- the isolated network 3 allows the supply of chilled water at regime by example of + 7 ° C / + 12 ° C, of the heating and air conditioning terminal 6.
- the valve three lanes 7 open in air conditioning mode on one lane 9 provides power of a finned battery 14 with cold fluid.
- this coil is an example of a cold fluid exchanger intended to produce frigories, other types of exchangers producing frigories can be used.
- the regulation of the cooling capacity is obtained by a two-way valve 13 controlled by a thermostat 18 as a function of the difference between a value of room temperature and room temperature.
- the fan 15 is necessarily in operation and may have several ventilation speeds. Note that switching the mode of operation of the fan 15 which is different in heating mode and in air conditioning mode, which can be stopped in heating mode, is obtained depending for example on the position of the three-way valve 7.
- the condensate drain can be carried out by injection into the network 3 via a pump 17 controlled as a function of the level of water in a condensate recovery tank.
- a safety device can allow the closure of the valve 13 in case of malfunction of pump 17.
- the liquids not being compressible, the condensed water introduced under pressure into the network 3 is rejected at a discharge valve 20 integrated on this one.
- the introduction of condensation water into the network 3 can cause a significant change in its pH
- a regulator for maintaining pH can be incorporated to avoid any risk of acidification of the network
- a alarm can be incorporated to signal a possible failure of the pH maintenance regulator or the need to recharge it as an element basic when the low level is reached.
- the device 6 includes control means 18 and electrical connection means 19 to an energy source capable of be the local electrical sector.
- heating devices 1 and cooling devices 4 can be mixed production systems such as heat pump, absorption, or independent, individual or collective, or be linked to a main heating or cooling network. Switching from one to the other can be obtained depending on the season in different ways. Through example you can use three-way valves between the fluid lines hot and cold fluid lines.
- the heating and air conditioning terminals 6 can be operated on a original isolated network 3 or on an isolated conventional central heating network thereafter.
- FIG. 2 represents another embodiment comprising two networks separate hydraulics allowing the transit of hot water for one and water cold for the other.
- the isolated network allowing the transit of cold water through example + 7 / + 12 which can be fitted as standard or later added to the room.
- the non-insulated central heating network 3 allows the supply of hot water from the heating and air conditioning terminal 6.
- a two-way valve 10 controlled by a thermostat 18 allows the regulation of the thermal power dissipated at a radiator 11 located on the front of the terminal 6, and a finned battery 12 arranged in series.
- the fan 15 is stopped, the ventilation of the battery to fins 12 being produced by the phenomenon of natural convection, or in ventilation particularly slow which, while remaining inaudible allows obtaining significantly higher thermal power.
- the cooling system 4 and the pump 22 are in service.
- the insulated cold water distribution network 21 allows the supply of cold water from the heating and air conditioning terminal 6.
- a two-way valve 13 controlled by a thermostat 18 allows the regulation of the cooling power dissipated at the finned coil 14.
- the fan 15 is necessarily in operation and may have multiple ventilation speeds. Switching the mode of operation of the fan 15 which is different in heating mode and in air conditioning mode, which can be off in heating mode, is obtained according to the type of regulation of terminal 6, which according to needs will regulate on valve 10 or on valve 13.
