TECHNICAL FIELD The present invention relates to a movable air conditioner in which a user side unit and a heat source side unit are provided on a common mount.

2. Description of the Related Art Conventionally, there has been known an air conditioner for spot air conditioning in which a user side unit and a heat source side unit are integrally provided on a movable mount.

For example, in Patent Document 1, an indoor unit having an indoor heat exchanger, an outdoor unit having an outdoor heat exchanger, and an indoor unit and an outdoor unit are arranged so that the suction ports of the indoor heat exchanger and the outdoor heat exchanger face each other. An air conditioner is disclosed that includes a mounted movable pedestal.

For example, in an air conditioner disclosed in Patent Literature 1, a drain pan is provided above an indoor unit installation table.

JP 2021-11984 A

This type of air conditioner is used for spot air conditioning in large-scale, high-temperature spaces in which it is difficult to install ordinary air conditioners, such as factories, workshops, warehouses, and gymnasiums. Cooled air must be blown out to reach far. Therefore, it is required to make the temperature difference between the intake air temperature and the blown air temperature larger than that of a general air conditioner, and to lower the blown air temperature.

However, if the temperature difference between the intake air temperature and the blowing air temperature is increased, the temperature of the moisture dripping from the user-side heat exchanger, etc., which functions as an evaporator, will drop, and moisture will adhere to the walls of the housing due to dew condensation. , these low-temperature moisture drips into the drain pan. When the drain pan receives such low-temperature moisture, dew condensation may occur on the lower surface of the drain pan.

For example, in an air conditioner in which the temperature difference between the intake air temperature and the blowing air temperature is about 15 degrees, the temperature of the moisture that drips onto the drain pan is low, and a large amount of moisture adheres to the lower surface of the drain pan. Then, the moisture on the lower surface of the drain pan generated by the dew condensation sometimes drips onto the floor surface of the space to be air-conditioned.

Similarly, in the heat source side unit, dew condensation occurs in the heat source side heat exchanger in a heating operation or the like in which the heat source side heat exchanger is used as an evaporator. Also, during cooling operations where the heat source side heat exchanger is used as a condenser, condensation may occur on the low-temperature refrigerant pipes leading to the compressor and on the walls of the housing, resulting in dripping of moisture from the heat source side unit. . However, in conventional air conditioners, the heat source side unit is not provided with a suitable drain pan.

The present invention has been made in view of the above circumstances, and its object is to prevent the dripping and scattering of water by a drain pan without condensation, and to powerfully blow out air cooled to a low temperature. To provide an air conditioner capable of

The air conditioner of the present invention comprises a user-side unit in which a user-side heat exchanger and a user-side fan are provided in a user-side housing, and a heat source-side heat exchanger, a heat source-side fan, and a compressor in a heat source-side housing. a heat source side unit connected to the user side unit via a refrigerant pipe; and a drain pan provided below the user side unit to receive moisture dripping from the user side housing. A heat insulating part is provided on the upper surface.

According to the air conditioner of the present invention, there are provided a user-side unit, a heat source-side unit connected to the user-side unit via a refrigerant pipe, and a drain pan provided below the user-side unit for receiving moisture dripping from the user-side housing. and a heat insulating portion is provided on the lower surface or the upper surface of the drain pan. As a result, even if low-temperature moisture drips from the user-side housing, it is possible to prevent dew condensation from occurring on the lower surface of the drain pan. Therefore, low-temperature air can be blown out from the user-side unit without wetting the floor surface of the air-conditioned space or the like with dew condensation water. Therefore, it is possible to obtain an air conditioner that exhibits excellent cooling performance with little scattering of water.

Further, according to the air conditioner of the present invention, the user side unit and the heat source side unit are arranged on a single movable frame, and the drain pan may be provided on top of the frame. good. As a result, the air conditioner can be easily moved in a large space such as a factory or a warehouse, and low-temperature air can be suitably blown to a place where cool air is required without scattering moisture.

Further, according to the air conditioner of the present invention, the number of heat transfer tube rows in the use side heat exchanger may be larger than the number of heat transfer tube rows in the heat source side heat exchanger. As a result, the ambient air sucked into the user-side unit is blown out from the windward side of the user-side heat exchanger to the leeward side while sufficiently repeating heat exchange. can increase the temperature difference between

Even in the cooling operation with such a large temperature difference, the drain pan can catch and drain dripping condensed water adhering to the user-side heat exchanger and the user-side housing. Therefore, the air conditioner can suppress splashing of moisture into the space to be air-conditioned and blow out suitable cool air, and even when used for spot air-conditioning, it exhibits a good air-conditioning effect. In addition, since the heat source side heat exchanger has a small number of heat transfer tube rows, excellent heat exchange efficiency can be obtained. Therefore, the air conditioner is excellent in energy saving.

Further, according to the air conditioner of the present invention, the drain pan may receive moisture dripping from the heat source side housing. As a result, it is possible to prevent the floor or the like of the space to be air-conditioned from getting wet due to dripping moisture from the heat source side unit. Therefore, it is possible to perform an air conditioning operation in which the temperature of the refrigerant sucked by the compressor is lowered. Also, even if the amount of dripping water from the heat source side unit is large, it can be received by the drain pan, so it is possible to perform heating operation in which the amount of condensed water in the heat source side heat exchanger increases. That is, even in the heating operation using the heat source side heat exchanger as an evaporator, a high-performance air conditioning operation with little splashing of water is possible.

Further, the air conditioner of the present invention may include a heat source side drain pan that is provided below the heat source side unit and receives moisture dripping from the heat source side housing. As a result, it is possible to receive and drain water dripping from the heat source side unit, thereby preventing the floor surface of the space to be air-conditioned from getting wet. Therefore, high-performance air conditioning operation with a large temperature difference can be performed. Further, for example, even in a heating operation in which the heat source side heat exchanger is used as an evaporator and the amount of condensed water in the heat source side heat exchanger increases, dripping of water from the heat source side unit can be received. Therefore, the air conditioner can also perform high-performance heating operation.

Fig. 3 is a cross-sectional view of the bottom plate of the drain pan of the air conditioner according to the embodiment of the present invention;

Hereinafter, air conditioners according to embodiments of the present invention will be described in detail based on the drawings.
FIG. 1 is a diagram showing a schematic configuration of an air conditioner 1 according to an embodiment of the present invention.
As shown in FIG. 1 , the air conditioner 1 is a device that performs an air conditioning operation, and has a user side unit 10 and a heat source side unit 20 mounted on a pedestal 40 . The air conditioner 1 is a movable powerful spot air conditioner in which a user side unit 10 and a heat source side unit 20 are integrated.

The user-side unit 10 is a device that mainly cools or heats the user-side air and supplies it. The user-side unit 10 has a configuration corresponding to an indoor unit of a general package air conditioner.

Specifically, the user-side unit 10 has a housing 11 as a user-side housing, which is a substantially box-shaped housing made of a metal plate material or the like. Inside the housing 11, a user-side heat exchanger 12 and a user-side fan 13, which are parts constituting a refrigeration cycle, are provided. This user side fan 13 is a propeller fan, and is rotationally driven by a motor (not shown).

The heat source side unit 20 is a device that mainly releases heat to or absorbs heat from the air on the exhaust side. The heat source side unit 20 has a configuration corresponding to an outdoor unit of a general packaged air conditioner.

Specifically, the heat source side unit 20 has a housing 21 as a heat source side housing which is a substantially box-shaped housing made of a metal plate material or the like. Inside the housing 21, a heat source side heat exchanger 22 and a heat source side fan 23, which are parts constituting a refrigerating cycle, are provided. This heat source side fan 23 is also a propeller fan, and is rotationally driven by a motor (not shown).

In the user-side unit 10, the housing 11, the user-side heat exchanger 12, and the user-side fan 13 are arranged in substantially the same outdoor installation specifications as the heat source-side unit 20. FIG. The user side unit 10 is formed with substantially the same specifications as the heat source side unit 20 in terms of weather resistance and waterproofness.

With such a configuration, the parts of the user side unit 10 and the heat source side unit 20 can be shared, and the productivity of the air conditioner 1 can be improved. In addition, since the user-side unit 10 is designed to be installed outdoors and has improved weather resistance and waterproofness, the cleaning performance of the user-side heat exchanger 12 is enhanced.

The user-side heat exchanger 12 of the user-side unit 10 is connected to the heat source-side heat exchanger 22 of the heat source-side unit 20 via refrigerant piping 28 . Specifically, the user-side heat exchanger 12 and the heat source-side heat exchanger 22 include a compressor (not shown) that compresses a low-pressure refrigerant to a high pressure, an expansion valve (not shown) that expands a high-pressure refrigerant to a low pressure, and refrigerant pipes. 28 and other refrigerant pipes (not shown) to form a vapor compression refrigeration cycle circuit. As the refrigerant used in the refrigeration cycle, for example, an HFC refrigerant or the like is adopted.

The housing 11 of the user-side unit 10 is formed with a suction port 15 that is an opening for sucking ambient air and a blowout port 16 that is an opening for blowing out air. The suction port 15 is provided with a user-side heat exchanger 12 that exchanges heat between the air sucked from the outside and the refrigerant. As a result, for example, during cooling operation, the air sucked from the outside is cooled by the refrigerant that evaporates in the user-side heat exchanger 12 .

The air outlet 16 is provided with a user-side fan 13 that blows out the air in the housing 11 that has exchanged heat with the user-side heat exchanger 12 . The user-side fan 13 is, for example, a propeller fan or the like, and is rotationally driven by a motor (not shown).

The air conditioner 1 according to the present embodiment is equipped with a particularly powerful user-side fan 13 . Specifically, the user-side fan 13 has, for example, a strong air-blowing ability to blow air from the air outlet 16 at a wind speed of 8 m/s. As a result, in a large-scale workshop such as a factory, a straight, strong wind can be delivered to a long distance, and only the working space can be efficiently cooled or heated by targeting the working space.

Further, the air outlet 16 is provided with a wind direction guide 14 for adjusting the flow direction of the air sent by the user side fan 13 . The wind direction guide 14 has an outer peripheral portion that surrounds the outer periphery of the user-side fan 13 and has, for example, a substantially cylindrical shape. The inside surrounded by the outer peripheral portion of the wind direction guide 14 is an opening connected to the blowout port 16 through which air flows, and a variable wind direction adjusting plate (not shown) for adjusting the air flow is provided there.

With such a configuration, the air cooled or heated by the user-side heat exchanger 12 so that the temperature difference with the surrounding air is sufficiently large can be efficiently flowed toward the work space that requires it. .

A pipe outlet 17 through which a refrigerant pipe 28 connected to the heat source unit 20 is inserted is provided on the front surface of the housing 11 of the user unit 10 . The piping outlet 17 is, for example, a knockout hole.

The housing 21 of the heat source side unit 20 is formed with a suction port 25 that is an opening for sucking air and a blowout port 26 that is an opening for blowing out air. The suction port 25 is provided with a heat source side heat exchanger 22 that exchanges heat between the air sucked from the surroundings and the refrigerant. As a result, for example, during cooling operation, the refrigerant in the heat source side heat exchanger 22 is cooled and condensed by the air flowing in from the suction port 25 . In other words, the air sucked from the suction port 25 exchanges heat with the refrigerant in the heat source side heat exchanger 22 and is heated.

The air outlet 26 is provided with a heat source side fan 23 that blows out the air inside the housing 21 that has undergone heat exchange with the heat source side heat exchanger 22 . The heat source side fan 23 is, for example, a propeller fan or the like, and is rotationally driven by a motor (not shown).

Further, the air outlet 26 is provided with a wind direction guide 24 for adjusting the blowing direction of the air sent by the heat source side fan 23 . The wind direction guide 24 has, for example, a substantially rectangular outer frame surrounding the heat source side fan 23, and is made of a metal plate material, a resin plate material, or the like.

The housing 21 of the heat source side unit 20 is formed with a pipe outlet 27 through which a refrigerant pipe 28 connected to the user side unit 10 is inserted. The piping outlet 27 is, for example, a knockout hole.

The user-side unit 10 and the heat-source-side unit 20 are provided on the mount 40 such that the suction port 15 and the suction port 25 for sucking air are opposed to each other. That is, the user-side unit 10 and the heat source-side unit 20 are arranged back-to-back so that the user-side heat exchanger 12 side and the heat source-side heat exchanger 22 side face each other.

In other words, the user-side unit 10 and the heat source-side unit 20 are arranged so that the air outlet 16 of the user-side unit 10 and the air outlet 26 of the heat source-side unit 20 face outward so that they blow air in opposite directions. It is

As described above, the user-side unit 10 and the heat-source-side unit 20 face the suction port 15 and the suction port 25 inward, and the air outlet 16 and the air outlet 26 are directed in opposite directions so that air is blown out in opposite directions. By arranging in such a manner, efficient air conditioning is realized for large-scale factories, distribution warehouses, and the like.

That is, the cooled or heated air can be efficiently and strongly blown from the outlet 16 of the user-side unit 10 to the work area to be air-conditioned. Then, exhaust heat air for air conditioning can be blown out to a space away from the space requiring air conditioning from the blowout port 26 of the heat source side unit 20 facing the side opposite to the blowout port 16 of the user side unit 10. can.

FIG. 2 is a perspective view showing a schematic configuration of the pedestal 40. As shown in FIG.
Referring to FIGS. 1 and 2, the mount 40 is a base that integrally supports the user side unit 10 and the heat source side unit 20 . The pedestal 40 is made of, for example, angle steel, channel steel, sheet metal processed steel, other steel materials, or the like. A base 41 is formed below the mount 40 and has a substantially rectangular frame-like outer periphery when viewed from above. The heat source side unit 20 is fixed to the top of the base 41 .

A user-side unit installation base 42 on which the user-side unit 10 is installed is formed on the gantry 40 . The user-side unit installation base 42 is formed to protrude upward from the top of the base 41 so that the bottom of the user-side unit 10 can be supported at a position higher than the bottom of the heat source-side unit 20 .

By providing the user-side unit installation table 42 on the upper part of the base 41, the user-side unit 10 is fixed at a high position. Since the user-side unit 10 is provided at a high position in this way, the position of the blow-out port 16 of the user-side unit 10 is raised, and cold air and warm air for air conditioning can be blown widely and efficiently to the work space. can be done.

A drain pan 30 is provided above the user-side unit installation table 42 . The drain pan 30 is a member for receiving water that adheres to and drips from the user-side heat exchanger 12 and the housing 11 of the user-side unit 10 and drains the water to a water pipe (not shown). By providing the drain pan 30, the water dripping from the user unit 10 can be collected and drained appropriately, and the water can be prevented from scattering in the working space.

Wheels 43 are provided near corners of the lower portion of the base 41 . The wheel 43 is, for example, a caster having a rubber wheel or the like, and may be a fixed wheel that can move in a predetermined direction on one side and a flexible wheel that can change direction on the other side. By providing the wheels 43 , the gantry 40 is configured to be movable while integrally supporting the user side unit 10 and the heat source side unit 20 .

FIG. 3 is a perspective view showing an outline of the drain pan 30. As shown in FIG.
As shown in FIG. 3, the drain pan 30 is a substantially dish-shaped member made of a metal plate material or the like. Specifically, the drain pan 30 has a substantially rectangular bottom plate 31 and side plate portions 32 bent upward from the sides of the bottom plate 31, and has a substantially box-like shape.

A support plate portion 33 bent outward is formed at a necessary location on the upper portion of the side plate portion 32 . The support plate portion 33 is a portion that is hung on the upper portion of the user-side unit installation base 42 (see FIG. 2) of the pedestal 40 (see FIG. 2) and supports the drain pan 30 . With such a configuration, the drain pan 30 can be easily attached.

A bottom plate 31 of the drain pan 30 is formed with a drain port 34 for discharging dripped water. A drain pipe (not shown) for flowing the air discharged from the drain pan 30 is connected to the lower portion of the drain port 34 .

Also, the bottom plate 31 is formed to be inclined at an appropriate angle so that water dripped from the user-side unit 10 (see FIG. 1) flows to the drain port 34 .
With such a configuration, the drain pan 30 can receive and drain condensed water that adheres to and drips from the user-side heat exchanger 12 and the housing 11 of the user-side unit 10 .

4 is a cross-sectional view of the bottom plate 31 of the drain pan 30. FIG.
As shown in FIG. 4 , a heat insulating portion 35 is provided on the bottom surface of the bottom plate 31 of the drain pan 30 . The heat insulating portion 35 is formed by, for example, adhering a synthetic resin sheet-shaped heat insulating member such as a foamed polyethylene sheet to the lower surface of the drain pan 30 .
By providing the heat insulating portion 35 on the lower surface of the drain pan 30 in this way, it is possible to prevent condensation from occurring on the lower surface of the drain pan 30 even if low-temperature moisture drips.

Although illustration is omitted, the heat insulating portion 35 may be provided on the upper surface of the bottom plate 31 of the drain pan 30 . The configuration in which the heat insulating portion 35 is provided on the upper surface of the drain pan 30 can also prevent condensation from occurring on the lower surface of the drain pan 30 .

1 to 4, the air conditioner 1 lowers the temperature of the air blown out from the user unit 10 toward the space to be air-conditioned, and cools the air from the user-side heat exchanger 12 and the housing 11 of the user-side unit 10. Even if low-temperature moisture drips, dew condensation does not occur on the lower surface of the drain pan 30. - 特許庁

That is, the air conditioner 1 can blow low-temperature air from the user-side unit 10 without wetting the floor surface or the like of the air-conditioned space with dew condensation water. As described above, the air conditioner 1 according to the present embodiment exhibits excellent cooling performance with little scattering of water.

As described above, the utilization side unit 10 and the heat source side unit 20 are arranged on a single movable pedestal 40 , and the drain pan 30 is provided on top of the pedestal 40 . As a result, in a large space such as a factory or a warehouse, the air conditioner 1 can be easily moved to the vicinity of a place that requires cooling, and the low-temperature air to the object to be cooled can be obtained without scattering moisture. can be suitably sprayed.

Although illustration is omitted, the drain pan 30 may be disposed so as to be able to receive moisture dripping from the housing 21, which is the housing on the heat source side. That is, the drain pan 30 may be formed in a large size and arranged in the vicinity of the upper portion of the base 41 so as to block the lower sides of both the user side unit 10 and the heat source side unit 20 .

With such a configuration, it is possible to prevent the floor or the like of the space to be air-conditioned from getting wet with the water dripping from the heat source side unit 20 . Therefore, in order to blow cool air from the user-side unit 10, air-conditioning operation can be performed in which the pressure of the refrigerant sucked by the compressor of the heat source-side unit 20 is low and the evaporation temperature is low.

In addition, even if a large amount of water drips from the heat source side unit 20, it can be received by the large drain pan 30, so the air conditioner 1 can also perform heating operation in which the amount of condensed water from the heat source side heat exchanger 22 increases. can. That is, even in heating operation using the heat source side heat exchanger 22 as an evaporator, high-performance air-conditioning operation with little splashing of water is possible.

Further, for example, a heat source side drain pan (not shown) may be separately provided below the heat source side unit 20 to receive moisture dripping from the housing 21 as the heat source side housing. As a result, the heat source side drain pan catches and drains the water dripping from the heat source side unit 20, and it is possible to prevent the floor surface of the space to be air-conditioned from getting wet. Therefore, a high-performance cooling operation can be performed with a large temperature difference between the intake air and the blown air.

Further, for example, even in a heating operation in which the heat source side heat exchanger 22 is used as an evaporator and a large amount of condensed water adheres to the heat source side heat exchanger 22, dripping of moisture from the heat source side unit 20 can be received. . Therefore, the air conditioner 1 having such a heat source side drain pan can also perform high-performance heating operation.

The utilization side heat exchanger 12 and the heat source side heat exchanger 22 of the air conditioner 1 are, for example, fin-and-tube heat exchangers. The number may be greater than the number of heat transfer tube rows in the heat source side heat exchanger 22 .

Specifically, the number of heat transfer tube rows in the utilization side heat exchanger 12 is preferably twice or more the number of heat transfer tube rows in the heat source side heat exchanger 22 . For example, the heat source side heat exchanger 22 has two rows of heat transfer tubes, while the utilization side heat exchanger 12 has four rows of heat transfer tubes.

As a result, the ambient air sucked into the user-side unit 10 is blown out from the windward side of the user-side heat exchanger 12 toward the leeward side while sufficiently repeating heat exchange. The temperature difference from the blown air temperature can be increased.

Even in cooling operation with such a large temperature difference, the drain pan 30 can receive and drain dripping condensed water adhering to the user-side heat exchanger 12 and housing 11 . Therefore, the air conditioning apparatus 1 can suppress splashing of moisture into the air-conditioned space and blow out suitable cool air, and exhibits a good air-conditioning effect even when used for spot air-conditioning.

As a result, for example, even if the temperature of the intake air exceeds 40 degrees on a hot day or the like, the temperature of the blown air can be lowered to 25 degrees or less. Therefore, the air conditioner 1 can send cool air of a suitable temperature to the user, which is also effective as a countermeasure against heat stroke, which was difficult with conventional air conditioners.

In addition, since the number of heat transfer tube rows in the heat source side heat exchanger 22 is small, unlike the case where the number of heat transfer tube rows in the heat source side heat exchanger 22 is increased, there is no concern that power consumption during cooling will be affected. That is, the heat source side heat exchanger 22 having a small number of heat transfer tube rows provides excellent heat exchange efficiency. Therefore, the air conditioning apparatus 1 can supply air cooled to a suitable temperature even if the ambient temperature is high, and has low power consumption and excellent energy saving.

An example in which the number of heat transfer tube rows in the utilization side heat exchanger 12 is four and the number of heat transfer tube rows in the heat source side heat exchanger 22 is two is given, but the utilization side heat exchanger 12 and the heat source side heat exchange The number of heat transfer tube rows in the vessel 22 is not limited to this.

For example, when the number of heat transfer tube rows in the heat source side heat exchanger 22 is two, the number of heat transfer tube rows in the utilization side heat exchanger 12 should be three or more. Further, for example, when the number of heat transfer tube rows in the heat source side heat exchanger 22 is three, the number of heat transfer tube rows in the utilization side heat exchanger 12 should be four or more.
Further, instead of increasing the number of heat transfer tube rows for the entire utilization side heat exchanger 12, a configuration may be adopted in which the number of heat transfer tube rows is partially increased.

Moreover, in the air conditioner 1 according to the present embodiment, a particularly powerful user-side fan 13 is mounted. Specifically, the user side fan 13 is installed so as to have a greater blowing capacity than the heat source side fan 23 . That is, the blowing air velocity of the user side fan 13 may be set higher than the blowing air velocity of the heat source side fan 23 . For example, the user-side fan 13 has a powerful air-blowing ability to blow air from the air outlet 16 at a wind speed of 8 m/s.

In addition, since the user-side fan 13 is a propeller fan like the heat-source-side fan 23, it is possible to use common parts, and in a large-scale workshop such as a factory, the airflow is strong in a straight line and the temperature difference is greater than that of the surrounding air. It can deliver cool air to long distances. Therefore, it is possible to efficiently cool or heat only the work space targeting the space where the user works.

In addition, this invention is not limited to the said embodiment. For example, the number, size, arrangement, etc. of the user-side units 10 and the heat source-side units 20 may be other design specifications. In addition, the number of heat transfer tube rows of the utilization side heat exchanger 12 and the heat source side heat exchanger 22 can be changed. other specifications can also be adopted.

Further, the air conditioner 1 according to the above-described embodiment has a movable configuration in which the user-side unit 10 and the heat source-side unit 20 are mounted on a common pedestal 40 and integrated. not to be The air conditioner 1 may be configured such that the user side unit 10 and the heat source side unit 20 are installed at different positions.

Even if the usage side unit 10 and the heat source side unit 20 are not integrated and are installed at different positions, the drain pan 30 having the heat insulation part 35 below the usage side unit 10 and the heat source side unit 20. is provided, it is possible to cool the sucked air to a low temperature with a large temperature difference while preventing scattering of condensed water. As a result, it is possible to obtain the air conditioning apparatus 1 that is excellent in air conditioning performance and energy saving performance, in which dew condensation water does not leak and suitably cooled low-temperature air can be efficiently sent to the object to be cooled.

In addition, various modifications are possible without departing from the gist of the present invention.
