Abstract

<P> The present invention relates to a dehumidification device by heat pump making it possible to ensure the dehumidification function even when the shutter system is in the all-fresh air position. <BR/> The installation comprises a set of air shutters and at least one air evaporator constantly swept by the flow of blown air, regardless of the position of the flaps. </P>

Description

The present invention relates to a dehumidification device by heat pump making it possible to ensure the dehumidification function even when the shutter system is in the all-fresh air position.

Dehumidification installations are already known, in particular for indoor swimming pools, comprising an air mixing box allowing operation while recycling air during periods of vacancy, partial admission of fresh air during periods of occupation, and in all fresh air during a period of deconcentration of chlorine in the basin hall or in an extreme period, when dehumidification is insufficient.

These installations have in particular been the subject of patents for the invention of
Jacques BERNIER N "7503133 of 31/01/75, N" 9201865 of 19/02192, N "9012975 of 19/10/90. In such installations, the evaporator (s) are always placed in the exhaust air flow and provide heat recovery of this during all fresh air, and operate in dehumidification when the installation operates in air recycling.

These installations have the drawback of only ensuring heat recovery in the all fresh air position and of no longer playing the role of dehumidifier, only the fresh air drier than the extracted air then playing this role. It is therefore necessary in this case to increase the air flow or allow the relative humidity of the air in the hall of the basin to drift upwards.

It is generally an object of the invention to provide a dehumidification installation which does not have the drawbacks of known installations.

It is in particular an object of the invention to allow dehumidification of the air even when the system is in the all fresh air position.

A dehumidification installation according to the invention comprises at least one evaporator placed on the fresh air circuit.

According to another characteristic of the invention, one or more evaporators placed on the return air circuit provide heat recovery in the all fresh air position and the dehumidification function in the recycling position.

The invention will be better understood from the following description given by way of example and with reference to the appended drawings in which:
Figure 1 is a diagram of an installation according to the invention comprising one or
several evaporators placed on the fresh air circuit.

Figure 2 is a diagram of an installation according to the invention further comprising
a heat recovery unit.

Figure 3 is a variant of the invention also comprising one or more
evaporators placed on the return air. Figure 4 is a variant of the invention comprising one or more condensers
to supplement or replace the air condensers.

An installation according to the invention in FIG. 1 comprises a ventilation box (1) comprising registers (shutters) (20), (21), (22) making it possible, according to their position, to operate the system in any fresh air, the shutters ( 21) and (22) are then open and the flap (20) is closed, or else to operate in any recycled air, the position of the flaps is then reversed. The positioning of the flaps in a mixture is also possible. In all fresh air operation, fresh air is admitted into the box through the flap (22), after passing over the filter (16), it enters the evaporator (10) where it loses its humidity, the air is then admitted to the air condenser (11) where it heats up.

The air evaporator preferably consists of a battery of finned tubes.

A final reheating is possibly carried out by the exchanger (t2). The air is then blown hot and dry into the room via the fan (14). The evaporator (1 0), the condenser (11) are part of the circuit of a heat pump whose motor element is the compressor (13). The extraction fan (15) ensures the return of moist air from the treated room, this air is discharged outside by the register (21); in case the system operates in recycling. The air is recycled by the register (20).

Unlike other dehumidifiers on the market, the evaporator (10) is placed on the fresh air network.

An installation according to the invention in FIG. 2 further comprises a heat recovery unit (31) on the extracted air, coupled to the exchanger (30) placed on the fresh air. The pair (30) + (31) is made up of a gravity, superimposed or wicked heat pipe system; it can also be constituted by a plate exchanger or by recovery batteries with water circulation or the like. In this system, the heat recovered by the device (31) is transferred to the device (30). In recirculated air operation, the device (30) + (31) makes it possible to pre-cool the moist air sucked in by the fan (15) before penetrate the evaporator (10), which improves the amount of water vapor condensed by the dehumidifier by around 35%
FIG. 3 is a variant comprising one or more additional heat pump refrigerant circuits, the evaporator (s) (34) of which are placed on the return air circuit. The evaporator (34) performs the role of dehumidification in operation with recycled air, the air then passing through the flap (20) to be dehumidified again by the evaporator (10).
The evaporator (34) only plays a role of heat recuperator, the cold air then being rejected via the flap (21) The heat pump circuits comprising the evaporator (s) (34) are in relation with one or more condensers (36) and require one or more compressors (33).

FIG. 4 is a variant of the invention in which the air condenser (s) (36) are replaced in whole or in part by one or more water condensers (35).

In all cases, the order of the different evaporators and condensers can be reversed.

The mixing box may include three motorized registers.

The principle of regulation is as follows - the installation includes means for regulating the temperature of the supply air acting first on the recovery of static heat then on the evaporator recuperators placed on the return air side and means for regulating the relative humidity of the treated room acting as a priority on the commissioning of the evaporators placed on the supply air side. Means for regulating the temperature of the water circulating in the water condensers will also be provided.

The working refrigerant of the heat pump circuits may be a pure fluid such as HFC R-134a, but may also be a zeotropic mixture of fluids.

All the thermodynamic part composed of evaporators, condensers, compressors, refrigeration accessories and possible heat recovery unit, will preferably be placed in a removable drawer (40) sliding in the box (1).

The invention allows numerous applications both in use in drying and in dehumidification. The most common application is the dehumidification of indoor pools.

The invention is not limited to dehumidification or drying of foodstuffs, it also applies to the air conditioning and cooling of premises.
