Condensing Waste Heat Rejection and Recovery Apparatus}

The present invention relates to a condenser.

Condensation waste heat removal and recycling apparatus.

A refrigerator using a condenser uses the principle of transferring heat from a low temperature object to a high temperature object. Generally, the refrigeration cycle of a refrigerator is hermetically compressed and is composed of a compressor, a condenser, an expansion valve (or a capillary tube), and a cooler (or an evaporator).

Each function of the refrigerating cycle component is that the refrigerant gas that has evaporated in the evaporator and absorbs heat from the medium to be cooled through the evaporator flows into the compressor through the suction pipe, and the compressed hot and high pressure refrigerant gas passes through the discharge pipe to the condenser. The refrigerant gas introduced into the condenser absorbs heat from the condensation medium (water or air) through the condenser to liquefy high temperature and high pressure gas, and the liquefied refrigerant is expanded by a pressure and temperature through the refrigerant liquid pipe. As it passes through, the pressure drops from the condenser pressure to the evaporator pressure, and the refrigerant in the evaporator causes evaporation to cool or freeze the medium to be cooled. This refrigeration cycle process is repeated repeatedly.

In order to complete the refrigeration cycle, the heat absorbed from the medium to be cooled by the evaporator and the heat corresponding to the work required to increase the refrigerant gas pressure to move the refrigerant gas to the outside of the refrigeration cycle must be removed.

The condenser with the function of converting the refrigerant gas into the refrigerant liquid is essential in the refrigeration cycle, and is air-cooled or water-cooled to remove heat to be removed through the condenser by heat transfer, and heat transfer in the form of direct heat and latent heat. Distinguished by evaporative condensation to remove.

However, the heat of condensation from the condenser is usually discharged to the atmosphere without being reused as energy or heat.

The technology to recycle the waste heat generated from the conventional water-cooled condenser is disclosed in Utility Model Publication No. 1999-001202 (hot water tank using the condenser waste heat of the heat exchanger) and 1992 ASHAE HANDBOOK HVAC (System and Equipment Applied Heat Pump and Heat Recovery) Systems).

And hot water generating hot water using the evaporator 202 for cooling the cooling water circulated from a cooling freezer condenser (not shown), the condensation hot water load unit 230 using the heat source of condensation hot water, and condensation hot water as a heating heat source. In order to reheat the condensed hot water from the tank 205, the condensed hot water supply pipe 210 for supplying condensed hot water to the hot water tank 205, and the condensed hot water load unit 230 and the hot water tank 205 The condensation hot water return pipe 211 circulated to the condenser 201, the condensation hot water return pipe 211 is installed in the conduit, condensation hot water circulation pump 212 circulating the condensation hot water, and a refrigeration condenser for cooling ( Discharged from the (not shown) Condenser waste heat of the heat pump, including a cooling water supply pipe 203 flowing into the air 202 and a cooling water return pipe 204 for circulating the cooling water absorbed heat while passing through the evaporator 202 to a cooling tower (not shown) The recycling apparatus part is comprised.

In addition, the hot water tank (205) for accommodating a hot water heating coil (not shown) using the condensed hot water as a hot water heating heat source and branched from the condensed hot water supply pipe (210) to heat the hot water tank (205). A condensation hot water supply distribution pipe 213 for supplying condensation hot water to the coil, a condensation hot water supply pump 206 installed in a conduit of the condensation hot water supply distribution pipe 213 and circulating condensation hot water, and the condensation hot water supply distribution pipe ( 213, a three-way automatic valve 207 having a function of controlling a flow rate by temperature and bypassing part or all of the condensed hot water to the condensed hot water return pipe 214, and the hot water tank 205. The hot water heating unit is configured as a condensation hot water return distribution pipe 214 that flows to the condenser 201 for reheating the condensation hot water cooled by connecting between the condensation hot water return pipe 211 from the heating coil.

A hot water reservoir 208 for storing hot water from the hot water tank 205 through a hot water supply circulation tube 220 and a water supply connected to a pipe of the hot water supply circulation tube 220 may supply water. Inlet pipe 223, the hot water supply pipe 222 for supplying hot water from the hot water reservoir 208 to the hot water using unit (not shown), the hot water reservoir 208 and the hot water tank 205 by connecting In order to reheat the hot water, the hot water return pipe 222 is circulated to the hot water tank, and the hot water circulating pump 209 is installed in the hot water return pipe 222 pipe to circulate the hot water.

As described above, a constitution of a condenser waste heat recycling apparatus unit of the heat pump, the hot water heating unit, and the hot water storage tank unit is configured to supply a hot water heating and heating or reheating heat source.

However, the technique related to the hot water tank using the condenser waste heat of the Utility Model Publication No. 1999-001202 of the prior art, the water temperature in the hot water tank is sharply increased when not using the hot water condensation is not condensed I have a problem,

In addition, when the state as described above, the air-cooled heat dissipation unit 106 installed by installing the method to cool the hot water in the hot water tank is proposed, but if the condensation hot water is not used, the inflow of water supply is also stopped accordingly to remove the condensation waste heat Since the air-cooled heat dissipation unit 106 needs to be completely cooled, the air-cooled heat dissipation unit 106 having a cooling condensation capacity of 100% is required, and for example, the air-cooled heat dissipation unit 106 is installed in a room such as a veranda. Indoor temperature rises rapidly and operation noise of circulation pump and cooling fan is generated by operation.

When the temperature rise of the room reaches the condensation temperature limit, there is a problem in that the air conditioner must be stopped until the condensation is restored and the condensation temperature is restored.

In addition, even when the air-cooled radiator 106 is operated, the temperature difference between the condensation temperature and the summer temperature is very small, while the cooling efficiency is low, while the heat transfer area of the air-cooled radiator 106 and the size of the cooling fan must be greatly increased. There is this.

In addition, since the amount of hot water used in the summer to operate the air conditioner when applied to an apartment or a home house is limited to washing or bathing, the heat dissipation effect of the condenser by only using hot water is low, and thus through the air-cooled heat radiating unit 106 installed by laying. Condensation dependency has to be increased and a separate energy cost for the operation of the cooling fan 108 and the circulation pump 109 included in the air-cooling radiator 106 is generated. Operation noise, outdoor unit power, installation constraints, etc.) can not be solved, and condensation waste heat reuse effect is low, and thus, there is a problem of increasing equipment cost, power cost, installation area, and complex equipment and operation rather than conventional air-cooled outdoor unit (not shown). .

The prior art using the waste heat of the heat pump condenser is a device for installing the chiller cooler and the heat pump together in a large building that operates the cooling year round, using the waste heat of the heat pump condenser as a heating heat source for heating and hot water, The condenser waste heat is recycled as a heating heat source in the required place, as a reheating heat source in a device requiring reheating, and as a heating heat source of hot water, and the chiller cooler has the function of sharing the heating and hot water heating with the heat pump. ,

Absorption chiller installations are more efficient if the heating and cooling sources are to be generated at the same time, and the condensation hot water of medium temperature is not increased unless the efficiency of the refrigerator is reduced and the compressor consumption power is increased and the condensation temperature is increased. Since it generates a low heat efficiency as a heating heat source, in order to heat the target heating fluid to a temperature close to the condensation hot water temperature, the temperature difference becomes narrower, so that the hot water heating device becomes larger.

Heat exchanger for heating hot water and piping and circulation pump for circulating hot water, and a reservoir for storing hot water require an initial equipment cost, but have a low practical effect and complexity.

In particular, condensed hot water is used as a heating heat source to store hot water generated through a hot water tank heat exchanger in a water storage tank, and it is impossible to take hot water of 30 ° C. or higher like ordinary hot water unless a separate reheating heat source device is configured. In addition, the low temperature hot water is significantly lower than the condensation hot water temperature, so the efficiency of using the hot water is reduced.

The present invention is to solve the problems of the prior art, an object of the present invention is a condenser of a refrigerator or air conditioner having a conventional air-cooled, water-cooled or evaporative condenser non-condensing hot water tank containing a refrigerant gas condensing coil To replace the condensation heat dissipation tank containing the condensation heat dissipation coil that dissipates the condensation heat of the refrigerant gas and condensation waste heat to the water-cooled condenser of the present invention consisting of a set to provide an efficient condensation waste heat removal and recycling device for easy condensation waste heat removal and waste heat recycling have.

As a technical idea for achieving the object of the present invention, the present invention is based on the absorption of condensation waste heat generated in a condenser such as a refrigerator or an air conditioner to recycle to hot water and heating hot water heat source, such as tap water as a condensation cooling medium The 1st stage condensation waste heat removal and waste heat recycling function that absorbs condensation heat by absorbing condensation heat by flowing low temperature water into condensation hot water tank, and by recycling low temperature water such as tap water into condensation heat dissipation tank, Two-stage condensation waste heat removal function to condense non-condensed refrigerant gas that may result from reduction or pause, and to absorb waste heat and dissipate it to low temperature water such as tap water used, and to remove and waste heat of the condensation waste heat of the first and second stages. Recycling function reduces or suspends the use of condensation hot water and condensation radiant tap water. As a temporary safety politics considering the occurrence of shafts, the condensation process is continuously carried out by discharging the hot condensation hot water stored in the condensation hot water tank to an appropriate condensation temperature or by introducing cold water such as tap water into the designated water storage device at the same time. The three-stage condensation waste heat removal function provides a more stable and efficient condensation waste heat removal and recycling device.

In order to circulate and flow the condensation hot water tank (1) The heating hot water supply apparatus, including the water tube 76 and a heating water circulating pump 77 is disposed in the heating hot water exchange tube 76, the channel is configured.

As described above, the condensation hot water supply unit and the heating hot water supply device are provided in the hot water tank 14 to supply the condensation hot water heated in the hot water tank and supply the heating hot water to the heating radiator. Present the configuration.

In addition, in the above-described embodiment, the barrier wall is formed in one tank to form a condensation condensation hot water part and a condensation heat dissipation part. have. In addition, the condensation hot water tank and the condensation heat dissipation tank may be provided with insulation means when insulation is required to prevent freezing in winter.

In addition, in the above-described embodiment, the condensation coil for one air conditioner (or freezer) is configured in the condensation hot water tank and the condensation heat dissipation coil is configured in the condensation heat dissipation tank. Multiple condensation heat dissipation coils may be constructed in one condensation hot water tank and condensation heat dissipation tank.

In addition, in the above-described embodiment, the condensation cooling medium of the condensation heat dissipation tank is described as low temperature water, such as tap water, which is used, but may also be used for washing heavy water or ground water or industrial water used in buildings.

In addition, in the above-described embodiment, the compressor chamber having soundproof means in consideration of the soundproof means at a predetermined position of the condensation hot water tank and the installation of the compressor in the compressor chamber as described above have been described above. It can be installed in combination in the area or in other places spaced apart. In this case, the aforementioned compressor chamber is excluded.

In addition, in the configuration of the embodiment to which the air conditioner indoor unit of FIG. 3 described above is applied, the condensed hot water supply unit and the heating hot water device unit of the hot water tank are described above, but as shown in FIG. 5, the condensed hot water supply unit and the heating radiant unit in the hot water tank are heated. The device portion can be configured.

In addition, the condensation hot water tank, the condensation heat dissipation tank, the automatic valve, the temperature control switch, the compressor, the tap water inlet and outlet, the condensation hot water outlet, the heat dissipation water outlet, the drain outlet, the refrigerant gas inlet, the refrigerant gas outlet, and the refrigerant liquid pipe with respect to the configuration of the above-described embodiment.

In addition, it may be configured as a unit in combination with the configuration constituting the package unit and the refrigerator (or air conditioner) components such as the compressor, evaporator (or cooler), expansion valve.

In addition, in the above-described embodiment of the condensation waste heat removal and recycling apparatus of the present invention, the refrigerant condensation of the air conditioner or the freezer has been described above, but it can be applied to the condenser of other condensed fluid other than the refrigerant.

In addition, in the above-described embodiment, the condensation coil and the condensation heat dissipation coil are directly connected to the pipeline.

As described above, the refrigerant gas or the refrigerant liquid is flowed. However, in case the condensation is sufficient due to the function of the condensation hot water tank, the bypass pipe is branched to the refrigerant condenser to the condensing coil outlet and the evaporator, and the condensing coil is not passed through the condensation radiating coil. By-pass refrigerant flow path through which the refrigerant can flow directly to the evaporator can be configured by laying.

In addition, as can be seen from the description of the above embodiment, the present invention is a cooler, a freezer, a constant temperature and a humidity pump and a heat pump configured with a refrigerant compressor such as a reciprocating type, a centrifugal type, a screw type, a scoroll type and a rotary type, which require a refrigerant condenser. It can be applied to the condensation apparatus of absorption chiller and absorption chiller and water heater.

As described above, according to the present invention, since the outdoor unit (or the cooling tower) is excluded from the air conditioner (or the freezer), power consumption (about 5 to 8% in proportion to the compressor power consumption) of the cooling fan and the cooling water circulation pump is saved. can do.

In addition, it is water-cooled and condensed, so even when installed indoors, such as a balcony, there is no noise and room temperature does not rise so that a comfortable indoor environment can be maintained.

In addition, the condenser waste heat can be converted into heating energy without using a separate hot water or heating hot water supply, and thus it can be used as hot water or heating hot water for home use, thereby saving energy.

In addition, since there is no operation noise and high temperature heat discharge, it is possible to prevent the occurrence of pollution and surrounding complaints caused by the conventional outdoor unit (or cooling tower).

In addition, based on the same condensation capacity, it is possible to absorb the heat of condensation at a flow rate of the low-temperature water, such as a small amount of tap water corresponding to about 20% of the flow rate of the cooling water of the cooling tower.

For reference, when the condensation heat amount of the water-cooled air conditioner 2RT (6,048 Kcal / hr) at room temperature is 7,800 Kcal / hr, the flow rate is assumed as follows.

1) Cooling tower coolant flow rate: approx. 1,560 l / hr

a. Inlet water temperature: 32 ° C. b. Outlet water temperature: 37 ° C. c. Temperature difference (Δt): 5 ° C

2) Low temperature water flow rate such as tap water: about 350 ℓ / hr

a. Inlet water temperature: 15 ° C. b. Outlet water temperature: 37 ° C. c. Temperature difference (△ t): 22 ℃

Therefore, condensation temperature water of 37 ° C generated by absorbing condensation waste heat such as tap water, which is introduced for condensation at a room temperature cooler or freezer, can be used by converting it into hot water or heating hot water for domestic use. In the case of using a special refrigerator with a high temperature, condensation hot water of a corresponding temperature may be generated and used.

In addition, while operating the air conditioner (or freezer) in the summer, it is possible to heat or heat the medium to be heated by using condensation waste heat without operating a boiler or supplying hot water from a specific facility. For example, when the room is humid during the rainy season, when heating is required, or when the bedroom, such as the elderly, where a higher room temperature is required, needs to be heated, and when a certain medium is heated or the room temperature needs to be raised.

Since the heating temperature level felt in the summer when the air conditioner is operated is significantly lower than the heating temperature in winter, only condensation water (less than 40 ° C) lower than the normal heating hot water temperature (about 60 to 70 ° C) can obtain a sufficient heating effect.

If there is a specific heat dissipation part (heating or heating part) that can absorb all the heat of condensation of the air conditioner or the freezer operated during the summer, condensation hot water of 37 ℃ discharges all the heat from the heat dissipation part If the temperature is assumed to be 32 ° C. (Δt 5 ° C.), condensation may be possible by the self-circulation of condensation hot water without introducing low temperature water such as low temperature tap water.

In other words, the heating circulation of 32 ℃ to circulate the condensation hot water tank absorbs the heat of condensation to make the heating hot water of 37 ℃, and the process of heating the heat radiation and heating circulating water in the heating heater can be made continuously.

As an effect of another example, it is assumed that the condensation cooling medium of a 1RT (3,024 Kcal / hr) air conditioner, which is mainly used for home use in apartments, is supplied to low temperature water such as tap water at about 15 ° C. The amount of water is as follows.

1) The amount of heat of condensation to be removed for 1 hour of operation is 3,900 Kcal / hr

2) Assuming that the limit temperature for condensation heat absorption of low temperature water such as tap water at 15 ° C is 37 ° C, the amount of low-temperature water, such as tap water, is about 175 liters.

That is, the air conditioner can be operated for about 1 hour with only low temperature water such as tap water at 15 ° C. filled in a condensed hot water tank having a low capacity of 175 liters.

In other words, if the condensation hot water tank of about 350 liters of water is installed if it is operated for 2 hours, the air conditioner can be operated without the flow of low temperature water such as tap water.

As an effect of another example, condensed hot water absorbing condensation heat of the air conditioner is assumed that a 5 RT (15,120 Kcal / hr) air conditioner is installed and operated in a restaurant where hot water and tap water consumption is large and continuity of consumption. The amount of generated is as follows.

1) Condensation hot water generation amount of about 37 ℃: about 3,700 ℓ / hr

2) Tap water temperature in the condensation hot water tank: about 15 ℃

In other words, in order to operate 5RT air conditioner for one hour, it is necessary to make 3,700 liters of tap water into 37 ℃ condensed water and use it all. However, when room temperature reaches an appropriate temperature level, compressor operation stops or operation by load stage. Therefore, the full operation rate of the air conditioner per hour will vary depending on the conditions, but it is estimated to be within about 70%, and the corresponding hourly condensation heat and condensation hot water generation may be reduced.

Therefore, when all the condensed hot water generated in conjunction with the operation of the air conditioner can be consumed, there is a practical and economic effect of using efficient cooling and free hot water.

However, when the consumption amount of condensation hot water does not meet the generated amount, it is possible to maintain the operation of the air conditioner by dissipating the uncondensed heat to the tap water used through the condensation heat dissipation tank.

In addition, the condensation waste heat elimination function, the efficient condensation waste heat recycling function, and the condensation hot water tank, the condensation heat dissipation tank, and the high temperature condensation as the means for achieving the economical operation of the condenser waste heat through the three steps of the present invention described above. Low temperature water supply equipment such as hot water drainage device, condensation hot water supply and return device, tap water, and automatic valves, temperature control switches, reverse valves and piping for each application can be used to construct a simple and efficient facility within the appropriate initial investment cost category. It works.

The technical scope of the present invention is not limited to the embodiments of the present invention described above, it should be clearly explained that all the obvious embodiments that can be predicted by those skilled in the art within the scope of the technical idea of the present invention. I do not see.
