Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to solve the technical problem that the air conditioner in the prior art is not suitable for a narrow installation space due to the size of the air conditioner, referring to fig. 1 to 6, the application provides an integrated outdoor unit 100 and an air conditioner. Heat exchange components of the air conditioner are all arranged in the integrated outdoor unit 100, and part of the indoor unit 200 exchanges heat through the connecting section 140 of the evaporator 130. The number of components of the indoor unit 200 is greatly reduced, and the heat exchanger 210 on the indoor side can be selected to have a proper structure or size, so that the indoor unit 200 can be applied to various building spaces with narrow spaces. The invention is explained in detail below with reference to specific embodiments and the drawing of the description.
In a first aspect, referring to fig. 1 to 4, the present invention provides an integrated outdoor unit 100 including a condenser 120 and an evaporator 130. The condenser 120 is connected to the compressor 110. The evaporator 130 is communicated with the condenser 120 through a refrigerant pipeline, the evaporator 130 is provided with a connecting section 140, and the connecting section 140 enters the room to communicate the indoor heat exchanger 210 with the room, so that heat exchange of indoor air is realized.
Referring to fig. 5, the compressor 110 compresses the gaseous refrigerant into a high-temperature high-pressure gaseous state, and sends the gaseous refrigerant to the condenser 120 for cooling, the cooled gaseous refrigerant is changed into a medium-temperature high-pressure liquid refrigerant, the liquid refrigerant is throttled and depressurized by the throttling component, the liquid refrigerant is changed into a low-temperature low-pressure gas-liquid mixture (the liquid occupies most part), the gas refrigerant is vaporized by the evaporator 130 absorbing the heat of the secondary refrigerant, and then the gaseous refrigerant returns to the compressor 110 for continuous compression and continuous circulation for refrigeration. The four-way valve 310 changes the flow direction of the refrigerant during heating, so that the refrigerant flows in the condenser 120 and the evaporator 130 in the opposite direction to that during cooling, thereby heating.
Referring to fig. 3 and 4, a four-way valve 310 is disposed between the compressor 110 and the condenser 120 to control a flow direction of the refrigerant, and an electronic expansion valve 320 is disposed between the condenser 120 and the evaporator 130. Specifically, the connection 1401 may be configured to use a tubular interface to introduce the fluid in the evaporator 130 into the room for heat exchange.
Compared with the prior art, the technical scheme provided by the embodiment of the application has the following advantages: the condenser 120 and the evaporator 130 are installed in the integrated outdoor unit 100, so that the structure of the integrated outdoor unit 100 is more compact, the length of a refrigerant connecting pipe is reduced, and the reliability and the service life of the outdoor unit are prolonged compared with those of a conventional outdoor unit of a household air conditioner. The indoor unit 200 exchanges heat with indoor air using the connection section 140. The connection section 140 is connected to the indoor heat exchanger 210, and is a split structure with the heat exchanger 210, so that the installation of the integrated outdoor unit 100 and indoor unit 200 is facilitated.
In the integrated outdoor unit 100 of the present invention, the condenser 120 and the evaporator 130 are installed together in the integrated outdoor unit 100, and accordingly, the condenser, the evaporator and the related electrical control modules of other heat exchange components are also installed in the outdoor unit, and the indoor unit only needs to keep basic switches and touch control components, such that the electrical safety of the indoor unit is higher.
Referring to fig. 3, in a preferred embodiment, the evaporator 130 includes a first heat exchanging portion 131 and a second heat exchanging portion 132, the first heat exchanging portion 131 is used for circulating a refrigerant, the second heat exchanging portion 132 is used for circulating a coolant, the second heat exchanging portion 132 is wrapped around the periphery of the first heat exchanging portion 131, and the connecting section 140 is in communication with the second heat exchanging portion 132. In this embodiment, a refrigerant flows through the first heat exchanging portion 131 of the evaporator 130, and heat exchange of the refrigerant is performed by air cooling, and since a part of the evaporator 130 needs to enter the room in this embodiment, the water cooling structure is more convenient to install. The second heat exchanging part 132 is connected to the connection section 140, so that the coolant flows into the connection section 140 from the evaporator body 131 and then flows back into the evaporator body 131, the refrigerant in the compressor 110, the condenser 120 and the evaporator 130 forms a closed loop, and the coolant has an independent supply loop and generally passes through the evaporator 130 in a circulating manner. The length and shape of the connection section 140 are different in consideration of the structure of the installation space and the thickness of the wall, and therefore, the connection section 140 is provided as a separate member, and preferably, the connection section 140 and the second heat exchanging part 132 are detachably assembled, thereby improving the assembling efficiency. Specifically, the first heat exchanging part 131 is a tube side, and the second heat exchanging part 132 is a shell side. In practical operation, the coolant can be domestic water, and the shell side can be directly communicated with a water circuit in a room. If domestic water is used, the water channel of the room is required to be connected to provide tap water for recycling, but the water is only used for supplementing water, and the water channel does not need to be communicated continuously after the water channel is used for circularly supplementing water. If other coolants are used, a separate reservoir is provided for storing the coolant. The coolant circulates between the evaporator and the inside heat exchanger. Normally, no replenishment is required unless there is a leak. The construction of the evaporator 130 and the connecting section 140 will now be described with additional reference to the coolant, and it will not be necessary to distinguish whether the coolant is water or another type.
Further, in the above embodiment, the evaporator body 131 is parallel to the wall, the connection section 140 passes through the wall, the second heat exchanging portion 132 is provided with the connection head 133, and the connection head 133 is disposed in an L-shape or a U-shape to connect the connection section 140. The evaporator 130 is disposed in the outdoor unit 100, the casing 160 of the outdoor unit 100 is spaced from the wall by a distance of 10cm, and the evaporator body 131 is usually disposed on a side close to the wall. When the connection segment 140 passes through the wall, in order to reduce the installation cost as much as possible in practical use, the length of the connection segment 140 in the wall should be shortened as much as possible and inserted into the wall substantially vertically, so that the direction between the evaporator body 131 and the connection segment 140 is inclined and the connection head 133 is used to perform the turning. In this embodiment, the connectors 133 are all arranged to turn 90 °, and the turning portions are rounded corners, so that the coolant can be gently turned to enter the connecting section 140.
Referring to fig. 5 and 6, or further, in the above embodiment, the connection section 140 is provided with the output section 141 and the return section 142, the coolant flows from the evaporator body 131 into the output section 141, and flows from the return section 142 into the evaporator body 131, and the output section 141 and/or the return section 142 are provided with the valve 150. The valve 150 may be a stop valve to allow the coolant to flow or block, or an adjusting valve such as a ball valve to adjust the coolant flow as required to control the indoor heat exchange efficiency and achieve a predetermined cooling or heating temperature.
The difference between fig. 5 and fig. 6 is that the condenser 120 adopts a water-cooling structure for heat exchange, and in summer of hot weather, the condenser 120 operates efficiently, which results in higher temperature, and the water-cooling structure can continuously and efficiently cool the condenser 120.
Continuing to refer to fig. 3, the connection section 140 adopts a tube structure, the secondary refrigerant circulates in the tube, so that heat exchange can be fully realized with the indoor side, heat loss of the refrigerant is avoided, the tube structure is easier to penetrate through the wall, and the secondary refrigerant is not easy to leak. The pipe structure occupies small space, can reduce the integral installation size of the indoor side, and can effectively avoid the limitation of indoor side installation.
Referring to fig. 2, in a preferred embodiment, the unitary outdoor unit 100 includes a casing 160, and the casing 160 includes a first chamber 161 and a second chamber 162. The compressor 110 is disposed in the first chamber 161. The condenser 120 is provided with a first fan 121 to exchange heat with air, the first fan 121 is disposed in the second chamber 162, and the evaporator 130 is disposed on an upstream side of the first fan 121 with respect to the condenser 120. The integrated outdoor unit 100 is divided into a first chamber 161 and a second chamber 162, and the first chamber 161 is used for installing a first fan 121 to allow air to enter and exchange heat with the condenser 120. Under the action of the first fan 121, air enters from the evaporator 130 side and passes through the condenser 120, and takes heat away from the condenser 120. Specifically, a partition plate is disposed between the first chamber 161 and the second chamber 162, and a control module in the air conditioner may be fixedly coupled to the partition plate.
Further, referring to fig. 3 and 4, in the above embodiment, the condenser 120 is provided with a first communicating portion 1201 for the refrigerant to enter and exit, the evaporator 130 is provided with a second communicating portion 1301 for the refrigerant to enter and exit, and the first communicating portion 1201 and the second communicating portion 1301 are disposed in the first chamber 161. The first communicating portion 1201 communicates with the compressor 110 through a pipe, and the second communicating portion 1301 communicates with the first communicating portion 1201 through a pipe. The first communicating portion 1201 is disposed in the first chamber 161 for accommodating the compressor 110, and the condenser 120 has a fin-tube structure, so that the second communicating portion 1301 and the first communicating portion 1201 are disposed on the same side, and the length of the communicating pipe is shortened, which contributes to a reduction in the number of components of the external unit.
Or further, referring to fig. 4, in the above embodiment, the condenser 120 includes a straight portion 1202 and a bent portion 1203. The first fan 121 is an axial fan, the straight portion 1202 is disposed on the air outlet side of the first fan 121, and the evaporator 130 is parallel to the straight portion 1202. The bent portion 1203 is provided on the outer peripheral side of the first fan 121. The straight portion 1202 and the bent portion 1203 of the condenser 120 form a half-surrounded structure for the first fan 121, so that the heat exchange area can be increased while the space of the external unit is fully utilized. The evaporator 130 is arranged in parallel with the straight portion 1202, and the arrangement of the two is more compact.
Preferably, there is a spacing between the flat 1202 and the evaporator 130, the spacing being in the range of 20-40 mm. In order to avoid direct heat exchange between the condenser 120 and the evaporator 130, the distance between the two should be kept between 20 mm and 40mm, which is a consideration for compactness.
In a preferred embodiment, the integral type outdoor unit 100 includes a casing 160, and the casing 160 includes a first mounting portion and a second mounting portion. The condenser 120 is connected to the first mounting portion, and the evaporator 130 is connected to the second mounting portion. The first and second mounting portions are used to mount the condenser 120 and the evaporator 130, so that the condenser 120 and the evaporator 130 maintain a stable distance. Specifically, the housing 160 is provided with a top cover and a bottom plate, and the first and second mounting portions are formed by passing screws through a connecting plate, which is generally a sheet metal member, so that the screws can be prevented from damaging the inner pipes of the condenser 120 and the evaporator 130. The first and second mounting portions may be provided at a plurality of positions of the condenser 120 and the evaporator 130 so that the condenser 120 is connected to the base pan, the top cover, and the partitions of the first and second chambers 161 and 162 in the foregoing embodiment, and is maintained relatively fixed to the bracket of the first fan 121 in the foregoing embodiment.
Referring to fig. 5 and 6, in a second aspect, the present invention further provides an air conditioner including the integrated outdoor unit 100 and the indoor unit 200. The indoor unit 200 is provided with a heat exchanger 210, and the connection section 140 is detachably connected to the heat exchanger 210. The indoor unit 200 exchanges heat with the connection section 140 through the heat exchanger 210. The heat exchanger 210 is configured to circulate a coolant therein to exchange heat with indoor air. The fluid medium has the advantages of large specific heat capacity and rapid circulation, wherein the secondary refrigerant medium also has the advantages of recycling and low cost. Since the connection section 140 is detachably connected to the heat exchanger 210 and has a split structure, the size and the dimension of the heat exchanger 210 can be selected according to actual needs. Specifically, the detachable connection can adopt an interface structure, and sealing is realized through a sealing ring.

The cooled high-pressure low-temperature refrigerant is throttled by the electronic expansion valve 320 and the pipeline to become a low-temperature low-pressure gas-liquid mixed state, and is subjected to evaporation heat exchange in the evaporator 130. The heat-exchanged refrigerant is sucked into the compressor 110 through the four-way valve 310 and the pipe unit. The operation of the heat exchange loop is controlled by the controller 300 according to a set program, and the process is repeated. The 4-temperature sensing bulb is used for detecting the temperature of different positions of the system, and is convenient for system control.
