Description

Combination heat exchange energy-saving air conditioning system {Combination heat exchange energy-saving air conditioning system}

The present invention relates to a combination heat exchange energy saving air conditioning system.

In most multi-use facilities where existing air conditioning systems are used, an increase in ventilation inevitably leads to an increase in heating and cooling energy consumption, so the goals of reducing energy consumption and carbon emissions in the building sector and mandating zero energy buildings are achieved at the national level. It can act as a huge burden. [Compared to general air conditioning methods, the energy consumption of the outdoor air conditioning method is at least 5 times greater]

Because of this burden, on the one hand, measures are being considered to purify indoor air containing infectious agents through HEPA filters or ultraviolet sterilization (UVGI) treatment while maintaining the minimum ventilation amount required by current related laws and recirculate it indoors. .

However, in order for this to be an effective alternative to prevent group infections of COVID-19 in multi-use facilities, mathematically speaking, an amount of indoor air equivalent to 5 to 6 ventilations per hour must be purified through a HEPA filter or ultraviolet sterilizer. More in-depth research is needed.

Many experts from all walks of life predict that the COVID-19 incident will bring about many changes in almost all areas of our society in the future.

Experts in the building air conditioning system field also believe that in the post-corona era, new air conditioning system technologies that can always ensure the safety of occupants from the risk of serious group infections that can occur at any time in multi-use facilities, while also providing excellent economic efficiency and energy performance, are continuously being developed and put into practice. We expect that proven technologies will be selected by the market more quickly than ever before.

In this situation, the air conditioning system including the heat pump is a new type of variable air volume air conditioning system that maintains indoor air quality and a comfortable environment with 100% outdoor air. However, it can compete with existing air conditioning systems in terms of energy consumption, and polluted indoor air is stored inside the air conditioner. Since 100% of the waste is discharged to the outside, the problem of cross contamination between rooms within the building through the air conditioning system, which can become a major problem when the current serious respiratory infectious disease spreads, can be fundamentally prevented.

In addition, in the existing air conditioning system we currently use, only about 20% of the supply air volume is fresh outdoor air introduced for ventilation purposes, and the remaining 80% of the supply air volume is air recovered from indoors, and the two air are mixed to save energy. After that, it is treated with a heating and cooling coil and the air is supplied indoors.

On the other hand, the electric outdoor air conditioning system can air-condition the building with 5 times the outdoor air volume of the existing air conditioning system (i.e., 5 times the minimum required ventilation amount) in the building without increasing energy consumption, given that the entire supply air volume is outdoor air.

The present invention was developed to solve the above problems, and provides a combination heat exchange energy-saving air conditioning system that can save energy by embedding a heat pump in the air conditioning system.

And it may include an elastic body 770 that provides elastic force to the second support pillar.

That is, the four-way fixing part 700 according to the present invention includes a first case, a first intermediate assembly, at least one first support frame, and a first support pillar formed on the heat pump device side, and a second case and a second intermediate assembly. The combination body, the support body, at least one second support frame, and the second support pillar are formed on all four corners inside the chamber of the air conditioning system, and are connected through a coupling frame 750 and an elastic body 770.

In addition, the four-way fixing part 700 according to the present invention allows the support body 732 to primarily absorb vibration and shock, and uses an elastic body 770 to absorb vibration and shock transmitted from the pair of supports 732. Thus, the cohesion can be maintained by secondary absorption.

The support body 732 includes a pair of friction fixtures 7321 in close contact with the heat pump device, an intermediate assembly 7322 formed on the upper part of each friction fixture, and the intermediate assembly 7322 and the first intermediate assembly. Alternatively, it consists of a rotating body 7323 that is connected and installed between the coupling member and the first intermediate coupling member and has both ends hinged.

That is, the friction fixture 7321 can support the four inner corners of the chamber of the air conditioning system by pushing the second intermediate assembly 722 in the diagonal direction so that they are formed at a position spaced a predetermined distance away from the heat pump device.

In addition, the rotating body 7323 connected to each friction fixture 7321 is hinged independently of each other and maintains the posture of the second intermediate assembly 722 together with the elastic body 760 even when an external force in a specific direction is applied. You can do it.

Meanwhile, an auxiliary absorption part 800 may be coupled to the lower center of the heat pump device to support the heat pump device at the top and to absorb vibration and shock from the chamber floor or floor at the bottom.

The auxiliary absorber 800 includes a body 810, an internal fastener 820, a main spring 830, a moving member 840, a subspring 850, and an external fastener 860.

Meanwhile, the auxiliary absorption unit 800 absorbs vibration or impact energy through elastic force when shock or vibration occurs.

For this purpose, the auxiliary absorber 800 includes an internal fastener 820 that is fixedly coupled to the body 810, a main spring 830 that is accommodated in the internal fastener 820 and is elastically deformed, and an internal fastener 830 that is elastically deformed. A moving member 840 and an internal binding body 820 that protrude from the lower part of the body 810 and are elastically supported by the main spring 830 to be slideably inserted into the binding body 820 are provided on the side portion of the body 810. It includes a subspring 850 that elastically supports and absorbs vibration energy transmitted to the side surface of the body 810.

That is, when the body 810 flows due to shock and vibration, a pulling force is applied to both ends, and the moving member 840 moves in the direction of separation from the internal binding body 820, thereby expanding the main spring 830. .

When it flows in the opposite direction, a pushing force acts on both ends and the moving member 840 moves in the direction of insertion into the internal binding body 820, thereby compressing the main spring 830.

In this way, vibration is absorbed while tension and compression are repeatedly performed using the elastic force of the main spring 830, so that the vibration force can be evenly distributed and dissipated.

In addition, the subspring 850 is in the form of a leaf spring arranged so that both sides are elastically supported by the first support body 870 and the second support body 880, and the other side is elastically supported on the peripheral surface of the internal binding body 820. It can be.

That is, when vibration occurs and the case flows in the direction in which the case is opened and the subspring 850 is stretched and elastically deformed, a pulling force is applied toward the internal binding body 820 and the vibration can be absorbed. Conversely, when vibration occurs and the case flows in a narrowing direction and the subspring 850 is compressed and elastically deformed, a pushing force is applied and the vibration can be absorbed.

Accordingly, when vibration occurs, it can be restored close to the origin, thereby improving durability against bending.

Meanwhile, the moving member 840 may be optionally equipped with a detection unit 900 that detects and reports vibration or impact energy, and this detection unit 900 is electrically connected to an external device that alerts a signal when vibration or impact is detected. connected.

At this time, the sensing unit 900 includes a body 910 that is detachably received in the moving member 840 and has one side open, and a moving ball 920 that is accommodated in the body 910 and moves in position by vibration energy. And, a cover part 930 coupled to the body 910 to cover the open part of the body 910 and prevent the moving ball 920 from leaving, and a cover part 930 on the inside of the body 910 and the cover part 930, respectively. A support portion 940 that protrudes and supports the moving ball 920 so that it can be seated, and a contact portion provided on the inside of the body 910 to transmit a signal to an external notification device depending on the presence or absence of contact when the moving ball 920 moves ( 950).

That is, when shock or vibration is applied in a range in which the body 910 does not shake while the moving ball 920 is seated on the support portion 940, the moving ball 920 moves in the internal space of the body 910 by inertial force. As soon as the moving force is removed while moving, it settles on the support portion 940 under its own weight.

In addition, when vibration energy is transmitted to the body 910 due to vibration or impact, and the moving ball 920 seated on the support portion 940 is moved irregularly, if it repeatedly touches the contact portion 950, the contact portion 950 recognizes that vibration or shock occurs and transmits a signal to an external notification device.

By the configuration of the auxiliary absorption unit 800 and the detection unit 900 as described above, the heat pump device can be supported once again, minimizing the possibility of the device moving, enabling more precise operation and avoiding severe vibration or shock. In this case, the operation can be temporarily stopped through a notification to an external device.

In the above, preferred embodiments of the present invention have been shown and described, but the present invention is not limited to the specific embodiments described above, and may be used in the technical field to which the invention pertains without departing from the gist of the present invention as claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be understood individually from the technical idea or perspective of the present invention.
