Fig. 1 shows the schematic diagram of the constant-temperature dehumidification system of air conditioner of one embodiment of the present of invention; And
Fig. 2 shows the operational flow diagram of the constant-temperature dehumidification system of air conditioner of the one embodiment of the present of invention in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
The constant-temperature dehumidification system of air conditioner of one embodiment of the present of invention is shown in Fig. 1, has comprised: condenser 2, evaporimeter 3, compressor 1; Similar with general air-conditioner, pipeline is by described compressor 1, and described condenser 2, described evaporimeter 3 in turn links together and returns described compressor 1, forms circulation.The present invention, between the condenser 2 and evaporimeter 3 of air-conditioner, specifically, is before the evaporimeter 3 of indoor set, arrange an aftercooler 4 (in figure indoor set shown in broken lines) again.When realizing constant temperature dehumidification, the gas of the HTHP that compressor 1 is discharged is condensed into the liquid of HTHP through condenser 2.Outdoor expansion valve between aftercooler 4 and condenser 2 is opened, the liquid refrigerants of HTHP is again through aftercooler 4 condensation of indoor section, release partial heat, work indoor two-port valve 6 (or other throttling arrangements) simultaneously between aftercooler 4 and evaporimeter 3 reducing pressure by regulating flow, cooling, evaporimeter 3 again through indoor section evaporates, and absorbs heat.Indoor evaporator 3 and aftercooler 4 be heat absorption and release simultaneously, accomplishes the effect not only dehumidifying but also do not change current environmental temperature, i.e. constant temperature dehumidification.
Preferably, aftercooler 4 can be a part for evaporimeter 3, by a two-port valve and other spaced-apart of evaporimeter 3.Aftercooler 4 also can be other heat exchanger of the prior art.
Preferably, between aftercooler 4 and condenser 2, expansion valve is set.Between described aftercooler 4 and described evaporimeter 3, throttling arrangement 6 is set.Preferably, throttling arrangement 6 is two-port valves.
Fig. 2 shows the operational flow diagram of the constant-temperature dehumidification system of air conditioner of the one embodiment of the present of invention in Fig. 1.In this embodiment, constant-temperature dehumidification system of air conditioner of the present invention also comprises, direct refrigeration pipe 8, is directly communicated with condenser 2 and evaporimeter 3, without aftercooler 4.Condenser 2 connects direct refrigeration pipe 8 and aftercooler 4 respectively by a triple valve 5.Also comprise, PCB control panel 7, control triple valve 5.
See Fig. 2, this embodiment is when air conditioner refrigerating runs, and PCB control panel 7 controls triple valve 5 and closes aftercooler 4 loop, and the direct refrigeration pipe 8 of conducting, lowers the temperature rapidly; When air-conditioning constant temperature dehumidification mode operation, pcb board controls triple valve 5 and closes direct refrigeration pipe 8, and conducting aftercooler 4, realizes constant temperature dehumidification.
Specifically, the following step can be divided into:
S100, start.
S110, state initialization.
S120, model selection, selects operational mode by user.
If user have selected S130 intelligent mode, then there is S140, indoor set temperature-sensitive bag detected temperatures.
S150 is by pcb board logic contrast_environment temperature and design temperature, if when S180 environment temperature is greater than air-conditioner design temperature, PCB control panel 7 to be satisfied detected temperatures for environment temperature-sensitive, judges and controls triple valve 5 and aftercooler 4 as closed condition, the direct refrigeration pipe 8 of conducting, realizes fast cooling; This is operational mode 1.
When S160 environment temperature is less than or equal to air-conditioner design temperature, PCB control panel 7, for environment temperature-sensitive bag detected temperatures, judges and controls triple valve 5 and aftercooler 4 as conducting state, closing direct refrigeration pipe 8.First when cold-producing medium is by aftercooler 4, carries out conduction of heat in space, make environment temperature be increased, also increase the refrigerating capacity of system simultaneously.Secondly cold-producing medium is undertaken freezing and absorbing heat by internal machine of air-conditioner during evaporimeter 3, and environment temperature is reduced; When evaporimeter 3 and aftercooler 4 act on simultaneously, environment temperature-sensitive testing environment temperature data of satisfying returns to PCB control panel 7, pcb board control system regulates the service ability of aftercooler 4, and the cold that evaporimeter 3 and aftercooler 4 are released and heat reach dynamic equilibrium.Realize constant temperature dehumidification thus, this is operational mode 2.
If user have selected S200 general modfel, then select air-conditioning to operate in S210 pattern 1 or S220 pattern 2 always.
According to constant-temperature dehumidification system of air conditioner of the present invention, there is following beneficial effect: the constant-temperature dehumidifying function that can realize air-conditioning, effectively improve room comfort level.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
