Description

Technical Field

[0001] The invention relates to the technical field of heating and ventilation, and in particular to a condenser heat recovery system of a heating and ventilation and air conditioning system. Background Art

[0002] The condenser of the HVAC system used in buildings, workshops, etc. is a key part of the refrigeration system. Its main function is to convert gas or vapor into liquid and quickly transfer the heat in the pipe to the nearby air. This is an exothermic process, so the temperature of the condenser is usually higher.

[0003] The heat exchange process of the condenser generates a lot of heat, which is usually discharged directly, resulting in heat energy waste. Some workshops may use this heat energy, mostly using it to directly heat gas or liquid. However, this method of heat energy utilization is relatively direct and cannot be combined with the actual environment, resulting in its single functionality. Summary of the invention

[0004] The present invention discloses a condenser heat recovery system for a heating, ventilation and air conditioning system, aiming to solve the technical problem that the heat energy utilization method of directly heating gas or liquid is relatively direct and cannot be combined with the actual environment, resulting in its single functionality.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A condenser heat recovery system of a heating, ventilation and air conditioning system, comprising a heat exchange mechanism, the heat exchange mechanism being connected to a condenser through a heat recovery pipeline, the heat exchange mechanism comprising a hot gas utilization mechanism and a hot water utilization mechanism, and the hot gas utilization mechanism and the hot water utilization mechanism are connected in parallel, and a partition mechanism is provided at the connection point;

[0007] The hot water utilization mechanism includes a second support bin, and a third heat storage layer is fixedly connected in the second support bin, a second water pipe is connected in the third heat storage layer, and an end of the second water pipe is simultaneously connected to the first water pipe and the water outlet pipe through a third solenoid valve, a front end of the first water pipe is connected to a front end of the second water pipe through a three-way pipe, and the three-way pipe is connected to an external drinking water pipe, and the first water pipe is arranged on one side of the partition mechanism and is located outside the third heat storage layer;

[0008] The hot gas utilization mechanism comprises a first support bin, and a first heat storage layer and a second heat storage layer are fixedly connected in the first support bin at the same time, and a gas transmission pipe group is arranged in the first heat storage layer and the second heat storage layer;

[0009] The inner walls on both sides facing each other of the first support bin are fixedly connected with a first air inlet and a first exhaust port, and the first air inlet and the first exhaust port are respectively located at two ends of the second heat storage layer; the inner walls on both sides facing each other of the second support bin are fixedly connected with a second air inlet and a second exhaust port, and the second air inlet and the second exhaust port are respectively located at two ends of the third heat storage layer; the first air inlet and the second air inlet are simultaneously connected to the heat recovery pipeline through a three-way pipe.

[0010] By providing a hot gas utilization mechanism and a hot water utilization mechanism, the heat energy recovered from the condenser can enter the second heat storage layer and the third heat storage layer. After the heat is stored in the two heat storage layers, when the gas passes through the gas transmission pipe group, the gas can be heated by the second heat storage layer, and the cold water can be heated through the third heat storage layer. The heated drinking water is more suitable for drinking in winter, and the heated gas is suitable for heating food and other items in workshops and residences. At the same time, based on the structure of the hot water utilization mechanism, hot water enters from the first water transmission pipe, and the heat of the hot water can be transferred to the first heat storage layer through the partition mechanism, thereby optimizing the heating efficiency of the hot gas, thereby realizing rapid cooling of the hot water, which is more suitable for drinking in summer. Therefore, this structure can adapt to the utilization of heat energy in different environments, and is closely integrated with the use of drinking water, thereby reducing the waste of heat energy and enriching the diversity of heat energy utilization.

[0011] In a preferred solution, the top ends of the hot gas utilization mechanism and the hot water utilization mechanism are simultaneously connected to a top cover, and the inner wall of the top end of the top cover is fixedly connected to a support frame, a waist-shaped groove is penetrated through the inner wall of one side of the second support bin, and the first water pipe passes through the waist-shaped groove, and the outer wall of the first water pipe is fixedly connected to a limit plate;

[0012] The partition mechanism includes a heat conducting plate and a heat insulating plate, and the heat conducting plate and the heat insulating plate are connected, and both are located between the first support bin and the second support bin, and a plurality of notches are equidistantly provided on the heat conducting plate and the heat insulating plate;

[0013] A heat exchanger is fixedly connected to one side of the first water delivery pipe, and a plurality of heat conducting plates are equidistantly arranged on one side of the heat exchanger, and the plurality of heat conducting plates pass through a plurality of slots respectively, and an inclined plate is fixedly connected to the top of the heat exchanger;

[0014] The other side of the first water pipe is fixedly connected with a connecting plate, and the outer wall of the connecting plate is connected with a supporting plate through a plurality of springs, the supporting plate is fixedly connected to one side of the third heat storage layer, and a hose is provided at the tail end of the first water pipe;

[0015] The top end of the inclined plate is fitted with an angled plug block, and the top end of the angled plug block is fixedly connected with a hydraulic rod, and the top end of the hydraulic rod is fixed to the top inner wall of the support frame.

[0016] By providing a partition mechanism, in the partition mechanism, if the heat conducting sheet is inserted into the heat conducting plate, a heat exchange path between the first water pipe and the first heat storage layer can be established; conversely, if the heat conducting sheet is only inserted into the heat insulating plate, the heat exchange path is cut off; under the action of the hose, the waist-shaped groove and the spring, the first water pipe can be translated to adapt to the movement of the heat conducting sheet; under this structure, the heat exchange between the first water pipe and the first heat storage layer can be cut off when the hot water utilization mechanism heats the cold water, thereby avoiding heat loss.

[0017] In a preferred embodiment, the gas pipe group of the hot gas utilization mechanism includes an air inlet pipe, the end of the air inlet pipe is simultaneously connected to a U-shaped air pipe and an air pipe through a first solenoid valve, and the tail end of the U-shaped air pipe is connected to the middle section of the air pipe;

[0018] A second solenoid valve is provided at the connection between the tail end of the U-shaped gas pipe and the gas pipe. The gas pipe and part of the U-shaped gas pipe are located in the second heat storage layer, and another part of the U-shaped gas pipe is located in the first heat storage layer.

[0019] By providing a gas pipe group, in the hot water utilization mechanism, the temperature of the hot water transferred to the first heat storage layer is generally lower than the condenser heat recovery temperature in the second heat storage layer. Therefore, when the gas passes through the gas pipe along the U-shaped gas pipe, it will go through a process from low temperature to high temperature. The gas heating efficiency is increased by adding a preheating step. When the hot water utilization mechanism uses the condenser heat recovery temperature to heat drinking water, the first solenoid valve and the second solenoid valve are closed synchronously. Since the first heat storage layer and the second heat storage layer are not connected, the low temperature of the first heat storage layer can be avoided, which affects the loss of gas heating heat.

[0020] As can be seen from the above, a condenser heat recovery system of a HVAC system includes a heat exchange mechanism, which is connected to the condenser through a heat recovery pipeline, and the heat exchange mechanism includes a hot gas utilization mechanism and a hot water utilization mechanism, and the hot gas utilization mechanism and the hot water utilization mechanism are connected in parallel, and a partition mechanism is provided at the connection; the hot water utilization mechanism includes a second support bin, and a third heat storage layer is fixedly connected in the second support bin, a second water pipe is connected in the third heat storage layer, and the end of the second water pipe is simultaneously connected to the first water pipe and the water outlet pipe through a third solenoid valve, the front end of the first water pipe is connected to the front end of the second water pipe through a three-way pipe, and the three-way pipe is connected to an external drinking water pipe, the first water pipe is arranged on one side of the partition mechanism and is located outside the third heat storage layer; the hot gas utilization mechanism includes a first support bin, and a first heat storage layer and a second heat storage layer are simultaneously fixedly connected in the first support bin, and a gas pipe group is provided in the first heat storage layer and the second heat storage layer. The condenser heat recovery system of the HVAC system provided by the present invention has the technical effect of being adaptable to the utilization of heat energy in different environments, and being closely integrated with the use of drinking water, thereby reducing the waste of heat energy and enriching the diversity of heat energy utilization.

[0037] Reference Figure 6 In a preferred embodiment, a connecting plate 1010 is fixedly connected to the other side of the first water pipe 702, and the outer wall of the connecting plate 1010 is connected to a support plate 1007 through a plurality of springs 1008, the support plate 1007 is fixedly connected to one side of the third heat storage layer 703, and a hose 1009 is provided at the tail end of the first water pipe 702.

[0038] Reference Figure 6In a preferred embodiment, the top of the inclined plate 1006 is fitted with an angled plug 1011, and the top of the angled plug 1011 is fixedly connected with a hydraulic rod 1012, and the top of the hydraulic rod 1012 is fixed to the top inner wall of the support frame 2. In the partition mechanism 10, the angled plug 1011 is pushed vertically by the hydraulic rod 1012. As the contact position of the angled plug 1011 and the inclined plate 1006 moves, it can drive whether the multiple heat conducting sheets 1004 are inserted into the heat conducting plate 1001. If the heat conducting sheets 1004 are inserted, A heat exchange path between the first water pipe 702 and the first heat storage layer 303 can be established in the heat plate 1001.

In the gas pipe group for transporting gas in the first support warehouse 301, the part of the U-shaped gas pipe 306 close to the partition mechanism 10 can use the heat in the first heat storage layer 303 to heat the gas. When the gas passes through the rear half of the U-shaped gas pipe 306 and enters the gas pipe 305 through the second solenoid valve 307, the hot water In the utilization mechanism 5, the temperature of the hot water transferred to the first heat storage layer 303 is generally lower than the condenser heat recovery temperature in the second heat storage layer 308. Therefore, when the gas passes through the gas pipe 305 along the U-shaped gas pipe 306, it will go through a process from low temperature to high temperature. The gas heating efficiency is increased by adding a preheating step. When the hot water utilization mechanism 7 uses the condenser heat recovery temperature to heat drinking water, the first solenoid valve 304 and the second solenoid valve 307 are closed synchronously. Since the first heat storage layer 303 and the second heat storage layer 308 are not connected, the low temperature of the first heat storage layer 303 can be avoided, which affects the loss of gas heating heat.

[0041] Working principle: The heat energy recovered from the condenser can enter the second heat storage layer 308 and the third heat storage layer 703 in the first support bin 301 and the second support bin 701 respectively through the three-way pipe.

At the same time, the base Regarding the structure of the hot water utilization mechanism 7, if the third solenoid valve 708 is opened and hot water enters from the first water pipe 702, the heat of the hot water can be transferred to the first heat storage layer 303 through the partition mechanism 10, thereby optimizing the heating efficiency of the hot air, thereby achieving rapid cooling of the hot water, which is more suitable for drinking in summer. The hot air with a higher temperature can reduce the amount of hot air used, thereby improving the utilization rate of the hot air. Therefore, this structure can adapt to the utilization of thermal energy in different environments, and is closely integrated with the use of drinking water, reducing the waste of thermal energy, and enriching the diversity of thermal energy utilization.
