As shown in fig. 1 to 13, the present invention provides an environment control integrated machine including an indoor unit part 100 and an outdoor unit part 200. The indoor unit part 100 of the environment control integrated machine comprises an air inlet pipeline, wherein the air inlet pipeline is provided with a first air inlet channel 110, a first air outlet channel 120 and a second air outlet channel 130, the first air inlet channel 110 is used for being communicated with the outside, and the first air outlet channel 120 and the second air outlet channel 130 are used for being communicated with the inside; the first air inlet channel 110 is selectively communicated with at least one of the first air outlet channel 120 and the second air outlet channel 130; the first air outlet channel 120 is provided with an evaporator 122 and a first heat exchanger 123, and the evaporator 122 is positioned at one side of the first air outlet channel 120 facing the first air inlet channel 110; the first heat exchanger 123 is located at a side of the evaporator 122 away from the first air inlet channel 110; a second heat exchanger 132 is disposed in the second air outlet passage 130.
The evaporator 122 in the first air outlet channel 120 has a main function of dehumidification; the dehumidification of the evaporator 122 may be accomplished using conventional arrangements in the art; for example, the evaporator 122 may absorb heat in the air surrounding it, such that the temperature of the surrounding air is reduced.
The main function of the second air outlet channel 130 is cooling and heating. Since the evaporator 122 inevitably absorbs heat during dehumidification, refrigeration: when the external temperature is high and the humidity is high, dehumidification refrigeration is desirable for users; when the external temperature is low and the humidity is high, the temperature of the original cool fresh air can be further reduced by dehumidification and refrigeration, so that the discomfort of the temperature is caused. Based on this, a first heat exchanger 123 is provided downstream of the first outlet passage evaporator 122.
When the temperature of the fresh air is suitable and the humidity is high, the fresh air can be dehumidified by the evaporator 122 in the first air outlet channel 120 only by opening the evaporator 122 in the first air outlet channel 120 and closing the second air outlet channel 130. When the humidity of the fresh air is proper and the temperature is higher or lower, the fresh air can be cooled or heated by the second heat exchanger 132 in the second air outlet channel 130 only by opening the second heat exchanger 132 in the second air outlet channel 130 and closing the first air outlet channel 120. When the humidity of the fresh air is higher and the temperature is higher or lower, the evaporator 122 and the first heat exchanger 123 in the first air outlet channel 120 and the second heat exchanger 132 in the second air outlet channel 130 are turned on, so that the fresh air can be dehumidified by the evaporator 122 in the first air outlet channel 120 and cooled or heated by the first heat exchanger 123 and the second heat exchanger 132.
A first air intake channel coarse filter 111 may be disposed at the inlet of the first air intake channel 110, and is mainly used for performing preliminary filtration on the fresh air coming from the outside. The outlet of the first air outlet channel 120 can be further provided with a first air outlet channel efficient filter 124, the outlet of the second air outlet channel 130 can be further provided with a second air outlet channel efficient filter 133, the first air outlet channel efficient filter 124 and the second air outlet channel efficient filter 133 are efficient filters, harmful substances in indoor air and outdoor air can be efficiently filtered, the PM2.5 concentration of fresh air is effectively reduced, and accordingly cleaning of fresh air is guaranteed. The first air inlet channel coarse filter 111, the first air outlet channel high efficiency filter 124 and the second air outlet channel high efficiency filter 133 can constitute bipolar filtration, ensuring the excellent indoor environment and the health of users. The first air-out channel high-efficiency filter 124 and the second air-out channel high-efficiency filter 133 are made of superfine glass fiber paper as a filter screen, offset paper or aluminum foil plates as partition plates, and novel polyurethane sealant is used for sealing, and the outer frame is made of galvanized plates, stainless steel plates and/or aluminum alloy profiles.
In addition, the environmental control integrated machine of the present embodiment further includes an outdoor unit portion 200, and the structure and implementation process of the outdoor unit portion 200 may be configured as conventional in the art.
Illustratively, the outdoor unit part 200 may include a compressor 201, a four-way reversing valve 202, a gas-liquid separator 203, and an outdoor heat exchanger 204 disposed outdoors; the switching of the corresponding channels in the outdoor unit portion 200 is achieved through the reversing of the four-way reversing valve 202, so that the outdoor unit portion 200 can provide the refrigerant for the corresponding states (i.e., corresponding forms) of the evaporator 122, the first heat exchanger 123, and the second heat exchanger 132 according to the working mode of the environmental control integrated machine.
Taking the refrigeration of the environment control integrated machine as an example, the low-pressure gaseous refrigerant is sucked by the compressor 201 and compressed into high-pressure steam after being separated by the gas-liquid separator 203 and then discharged to the outdoor heat exchanger 204; the outdoor air takes away the heat emitted by the high-pressure gaseous refrigerant in the outdoor heat exchanger 204, so that the high-pressure gaseous refrigerant entering the outdoor heat exchanger 204 is converted into low-pressure steam; the low pressure steam flowing from the outdoor heat exchanger 204 passes through an expansion valve and then enters the evaporator.
According to the environment control integrated machine provided by the embodiment, through the arrangement of the first air outlet channel 120 and the second air outlet channel 130, and the arrangement of the evaporator 122, the first heat exchanger 123 and the second heat exchanger 132 in the first air outlet channel 120 and the second air outlet channel 130 respectively, the environment control integrated machine can have the capacities of dehumidification, refrigeration and heating, and the requirements of people on fresh air, dehumidification and cold and hot loads are met. Meanwhile, the environment control integrated machine can also have more working modes, namely functional modes, so as to meet various demands of people. According to different requirements, a user can select to open different channels, and the method is suitable for various environments.
Optionally, a fresh air direct-current channel 170 and a heat recovery channel 180 are arranged between the first air inlet channel 110 and the first air outlet channel 120 and the second air outlet channel 130 in parallel, and the first air inlet channel 110 is selectively communicated with one of the fresh air direct-current channel 170 and the heat recovery channel 180.
On the premise of pleasant external temperature, the fresh air direct-current channel 170 provides a channel for inflow of outdoor air, and fresh air does not need to be forced to enter the heat recovery channel 180 for cold-heat exchange, so that the environment control integrated machine can meet the indoor cold-heat load requirement by utilizing an outdoor natural cold source in spring and autumn.
When the external temperature is higher or lower than the comfort temperature, the fresh air direct-current channel 170 is closed, the fresh air is forced to flow into the heat recovery channel 180 and exchange heat with exhaust air, so that the cold and heat loads of the fresh air can be reduced, and the energy consumption is reduced. A plurality of heat recovery elements 183 are installed in series in the heat recovery channel 180, and the heat recovery elements 183 may be heat exchange cores. The heat recovery element 183 is a high-efficiency heat recovery element, and has a heat recovery efficiency of 75% or more, so that the exhaust heat and cold load can be effectively recovered, and the energy consumption of the environmental control integrated machine can be reduced.
The environment control integrated machine adopts the annual working condition design, and the fresh air direct-current channel 170 in spring and autumn effectively reduces wind resistance and reduces the use of the heat recovery element 183, so that the service life of the heat recovery element 183 is prolonged.
In the embodiment, when the external temperature is higher or lower than the comfort temperature, the heat exchange core is used for efficiently utilizing the exhaust air to exchange heat; thereby maximally improving the comfort of fresh air flowing into the room.
The environment control integrated machine has more working modes to adapt to different external environments by being provided with the fresh air direct-current channels 170 and the heat recovery channels 180 which are connected in parallel, so that various demands of people are met, and the environment control integrated machine has a wider application range to be suitable for more regions.
Optionally, a dehumidifying valve 121 is disposed on a side of the first air outlet channel 120 facing the first air inlet channel 110 in the present embodiment, so that the first air outlet channel 120 is selectively communicated with the first air inlet channel 110 through the dehumidifying valve 121; a load valve 131 is arranged on one side of the second air outlet channel 130 facing the first air inlet channel 110, and the second air outlet channel 130 is selectively communicated with the first air inlet channel 110 through the load valve 131; a fresh air valve 171 is arranged at the joint of the first air inlet channel 110 and the fresh air direct-current channel 170, and the first air inlet channel 110 is selectively communicated with the fresh air direct-current channel 170; a heat recovery valve 181 is provided between the first air intake passage 110 and the heat recovery passage 180 so that the first air intake passage 110 is selectively communicated with the heat recovery passage 180.
The dehumidifying valve 121 controls whether the fresh air flows into the first air outlet channel 120, and also controls the flow rate of the fresh air flowing into the first air outlet channel 120, so that the evaporator 122 dehumidifies the fresh air entering the first air outlet channel 120, and the first heat exchanger 123 performs cooling or heating treatment on the dehumidified fresh air.
The load valve 131 controls whether the fresh air flows into the second air outlet channel 130, and also controls the flow rate of the fresh air flowing into the second air outlet channel 130, so that the second heat exchanger 132 performs cooling or heating treatment on the fresh air entering the second air outlet channel 130.
The user can only open the dehumidification valve 121 to open the first air outlet channel 120, can also only open the load valve to open the second air outlet channel 130, and can also simultaneously open the dehumidification valve 121 and the load valve 131 to open the first air outlet channel 120 and the second air outlet channel 130, so as to ensure that purified fresh air continuously flows into a room.

In this mode, both the fresh air valve 171 and the heat recovery valve 181 are in a closed state to simultaneously close the fresh air direct current channel 170 and the heat recovery channel 180, thereby preventing outdoor air from entering the room.
In this mode, the humidity of the fresh air entering the first chamber 140 is higher, so that the evaporator 122 in the first air outlet channel 120 is turned on to dehumidify. The evaporator 122 dehumidifies and simultaneously inevitably cools, so that the temperature of the fresh air which is cool in winter is further reduced, and the first heat exchanger 123 which is positioned in the first air outlet channel 120 and is positioned at the position of the lower wind of the evaporator 122 is started to heat the fresh air.
In order to realize the dehumidification function of the evaporator 122 and the heating function of the first heat exchanger 123, the evaporator 122 and the first heat exchanger 123 are connected to the compressor 201, the four-way reversing valve 202, and the gas-liquid separator 203 through a first valve 207, a third valve 209, a sixth valve 212, an eighth valve 214, a tenth valve 216, and a second expansion valve 206. In this mode, the four-way reversing valve 202 is in reversing line communication.
The mode is applied to winter, the carbon dioxide concentration of exhaust meets the requirement, and the temperature of exhaust is greatly higher than the outdoor temperature, so that the mode is adopted to reduce the energy consumption for heating. But the higher humidity of the exhaust air requires the evaporator 122 to dehumidify.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
