Definitions
- the present invention relates to a refrigeration cycle apparatus intended for uses such as refrigeration, air conditioning, and hot-water supply.
- This apparatus includes an evaporator, a compressor, a first heat exchanger, a second heat exchanger, an expansion valve and a bypass route.
- the first heat exchanger is connected to an outlet side of the compressor and exchanges heat between a refrigerant from the compressor and hot water.
- the second heat exchanger is connected to an outlet side of the first heat exchanger and exchanges heat between the refrigerant from the first heat exchanger and hot water.
- the bypass route connects the outlet side of the first heat exchanger to an inlet side of the compressor or an inlet side of the evaporator via a bypass valve. In the first heat exchanger and the second heat exchanger, hot water is sent from the second heat exchanger to the first heat exchanger in this order.
- WO2014111012A1 discloses an internal cold and heat balance system combining a lithium bromide unit and a cold storage comprises a compressor, a heat-source side heat exchanger, a heat-source side heat balancer, a thermostatic expansion valve, a cold-source side heat exchanger, the cold storage and a liquid-vapor separator which are connected in series by pipelines.
- the heat-source side heat balancer and the lithium bromide unit are connected in series.
- a condenser included in a typical refrigeration cycle apparatus includes a header that distributes a refrigerant to be taken into a condenser body. If the refrigerant to be taken into the header is in a gas phase, the header can distribute the refrigerant evenly among individual refrigerant paths provided in the condenser body. However, if the discharge gas refrigerant discharged from the compressor is derived of heat before flowing into the condenser and is condensed into a state of two-phase gas-liquid, the header cannot distribute the refrigerant evenly. Consequently, the performance of the refrigerator may be deteriorated.
- Embodiment 1 in which the water warmed by the waste-heat heat exchanger is introduced into the water storage tank and is heated therein, if the temperature of the water in the water storage tank is below a preset temperature, the water in the water storage tank is further heated with an electric heater provided in the water storage tank. Thus, the temperature of the water is raised to the preset level. Hence, the amount of heat generated by the heater can be made far smaller than in a case where no waste heat is utilized, producing a great energy-saving effect. Moreover, the capacity of the electric heater can also be reduced, leading to a possible cost reduction.
- Fig. 1 is a diagram illustrating a configuration of a refrigeration cycle apparatus, which is not part of the invention.
- the refrigeration cycle apparatus illustrated in Figure 1 is merely used for a better understanding of the current application.
- the refrigeration cycle apparatus includes a refrigerator 100, and a water heater 101 provided as a hot-water-supply system separately from the refrigerator 100 and that supplies hot water to a sink cabinet or any other like equipment.
- the refrigerator 100 illustrated in Fig. 1 includes a compressor 1 and a condenser 2 that are provided thereinside, and an expansion valve 3 as a pressure-reducing unit and an evaporator 4 that are provided in a showcase 102 installed in a store such as a convenience store.
- the refrigerator 100 and the showcase 102 are connected to each other by a refrigerant pipe 11, whereby a refrigeration cycle in which a refrigerant circulates through the compressor 1, the condenser 2, the expansion valve 3, and the evaporator 4 is provided.
- a waste-heat heat exchanger 5 is provided between the compressor 1 and the condenser 2.
- a high-temperature, high-pressure discharge gas refrigerant discharged from the compressor 1 flows through the pipe 11 into the waste-heat heat exchanger 5 and then into the condenser 2 provided in the refrigerator 100.
- water as a heat-exchange object is introduced from a water storage tank 6 included in the water heater 101 through a water pipe 12 into the waste-heat heat exchanger 5.
- the water pipe 12 is provided with a water-circulating pump 7.
- the water pipe 12 forms a circuit through which the water in the water storage tank 6 is made to flow into the waste-heat heat exchanger 5 and is then returned to the water storage tank 6.
- the water introduced into the waste-heat heat exchanger 5 exchanges heat with the discharge gas refrigerant introduced into the waste-heat heat exchanger 5 through the refrigerant pipe 11 and is then returned into the water storage tank 6.
- a water supply pipe (not illustrated) is connected to a portion of the water pipe 12 that is on the suction side of the water-circulating pump 7. Water from a faucet is supplied into the water pipe 12 through the water supply pipe.
- the water storage tank 6 is provided thereinside with an electric heater 8 that heats the water in the water storage tank 6 (as a matter of convenience, water including heated hot water is hereinafter referred to as water).
- a control unit 110 controls the electric heater 8 to heat the water in the water storage tank 6 if the hot water to be supplied has a temperature lower than or equal to a preset temperature.
- the condenser 2 is a multi-path heat exchanger having a plurality of refrigerant paths.
- the condenser 2 includes a condenser body 21, and a distributor 22 provided on the refrigerant-inlet side of the condenser body 21.
- the distributor 22 distributes the refrigerant among the refrigerant paths.
- the high-temperature, high-pressure discharge gas refrigerant compressed by the compressor 1 is introduced into the waste-heat heat exchanger 5 through the refrigerant pipe 11, and waste heat thereof is utilized.
- the discharge gas refrigerant introduced into the waste-heat heat exchanger 5 exchanges heat with the water that is introduced into the waste-heat heat exchanger 5 from the water storage tank 6 of the water heater 101 by the water-circulating pump 7, whereby the refrigerant is cooled. Meanwhile, the water that has flowed into the waste-heat heat exchanger 5 is heated as a result of heat exchange with the discharge gas refrigerant. The heated water returns to the water storage tank 6 through the water pipe 12.
- Evenly distributing units are roughly categorized into two types: a single-phase gas distribution type in which the refrigerant is evenly distributed by controlling the refrigerant to be in a state of single-phase gas (that is, the refrigerant is prevented from falling into a state of two-phase gas-liquid) at the inlet of the condenser 2 (the outlet of the waste-heat heat exchanger 5); and a two-phase gas-liquid distribution type in which the refrigerant is evenly distributed even if the refrigerant at the inlet of the condenser 2 (the outlet of the waste-heat heat exchanger 5) is in a state of two-phase gas-liquid.
- a first evenly distributing unit is a gas-liquid separator 13, which will now be described in detail.
- the gas-liquid separator 13 is provided at the inlet of the condenser 2 and separates a two-phase gas-liquid refrigerant discharged from the waste-heat heat exchanger 5 into a liquid refrigerant and a gas refrigerant. Hence, even if the refrigerant at the inlet of the condenser 2 is two-phase gas-liquid, the two-phase gas-liquid refrigerant is made to flow through the gas-liquid separator 13 before flowing into the distributor 22. Thus, a single-phase gas refrigerant can be made to flow into the distributor 22 of the condenser 2.
- a header can be employed as the distributor 22 so that the refrigerant is evenly distributed among the refrigerant paths of the condenser body 21.
- the liquid refrigerant obtained through the separation by the gas-liquid separator 13 flows through a pipe 13a and is merged with the liquid refrigerant at the outlet of the condenser 2.
- a second evenly distributing unit is a unit that controls the capacity of the compressor 1 such that the refrigerant at the outlet of the waste-heat heat exchanger 5 is in a state of single-phase gas.
- the second evenly distributing unit will now be described in detail.
- Embodiment 1 the operation in winter is regarded as a condition under which the refrigerant is most likely to be condensed in the waste-heat heat exchanger 5.
- the refrigerant flowing into the condenser 2 can always be kept in a state of single-phase gas while the refrigeration cycle apparatus is in operation.
- the control unit 110 reduces the flow rate of the water by controlling the water-circulating pump 7 and thus reduces the amount of heat exchange in the waste-heat heat exchanger 5, thereby raising the degree of superheat of the refrigerant at the outlet of the waste-heat heat exchanger 5. Since the degree of superheat of the refrigerant at the outlet of the waste-heat heat exchanger 5 is raised, the refrigerant at the outlet of the waste-heat heat exchanger 5 turns into a single-phase gas refrigerant.
- the refrigerant to be cooled is not condensed.
- the water may be heated in advance by the electric heater 8 provided in the water heater 101 or by a separate heat source.
- a sixth evenly distributing unit allows only a portion of the discharge gas refrigerant to flow into the waste-heat heat exchanger 5 and to exchange heat with water if the temperature of the water flowing into the waste-heat heat exchanger 5 is below the condensing temperature of the refrigerant. In contrast, if the temperature of the water flowing into the waste-heat heat exchanger 5 is higher than or equal to the condensing temperature of the refrigerant, the sixth evenly distributing unit allows all portions of the discharge gas refrigerant to flow into the waste-heat heat exchanger 5 and to exchange heat with the water.
- the sixth evenly distributing unit will now be described in detail.
- the refrigerant flowing into the condenser 2 is a gas refrigerant, the refrigerant can be evenly distributed by the distributor 22.
- Fig. 4 is a diagram illustrating a configuration in which the sixth evenly distributing unit is provided to the refrigeration cycle apparatus according to Embodiment 1 of the present invention.
- Fig. 5 is a table summarizing operations of switching valves illustrated in Fig. 4 , on the basis of the relationship between the temperature of the water flowing into a waste-heat heat exchanger illustrated in Fig. 4 and the condensing temperature.
- a flow control valve may be provided to the bypass 30, and the opening degree of the flow control valve may be controlled by the control unit 110.
- a seventh evenly distributing unit includes an inlet pipe 22b whose diameter is set such that, if the refrigerant discharged from the waste-heat heat exchanger 5 is in a state of two-phase gas-liquid, the refrigerant is distributed in a flow pattern of an annular flow or an annular dispersed flow.
- the seventh evenly distributing unit will now be described in detail.
- the distributor 22 may be a header as illustrated in Fig. 2 .
- a distributor illustrated in Fig. 6 is preferably employed as the distributor 22.
- the distributor 22 illustrated in Fig. 2 includes the plurality of branch pipes 22c connected to the side face of the main pipe 22a.
- the distributor 22 illustrated in Fig. 6 includes an inlet pipe 22b having one end thereof connected to a refrigerant-inlet-side end of a main pipe 22a, and a plurality of branch pipes 22c each having one end thereof connected to the refrigerant-outlet side of the main pipe 22a and the other end thereof connected to a corresponding one of the plurality of refrigerant paths provided in the condenser body 21.
- the distributor 22 has a refrigerant inlet (distribution port) leading to the branch pipes 22c.
- the refrigerant inlet is provided at a liquid-film-generated part 23 of the main pipe 22a.
- the diameter of the inlet pipe 22b is set such that the refrigerant flowing through the inlet pipe 22b forms a flow pattern of at least an annular flow.
- the distributor 22 of the condenser 2 has two branch pipes 22c, whereby only two distribution lines leading to the condenser body 21 are provided.
- the eighth evenly distributing unit will now be described in detail.
- the number of refrigerant paths provided in the condenser 2 is set to two, that is, only two distribution lines leading to the condenser body 21 are provided.
- the refrigerant can be distributed more evenly to the individual refrigerant paths.
- setting the flow pattern of the refrigerant to an annular flow or an annular dispersed flow or employing an orientation that is not influenced by gravity is more effective for even distribution.
- the amount of heat exchange by the waste-heat heat exchanger 5 needs to be limited so that the refrigerant at the inlet of the condenser 2 does not fall into a state of two-phase gas-liquid.
- the seventh or eighth evenly distributing unit even if the refrigerant at the inlet of the condenser 2 turns into a state of two-phase gas-liquid, the refrigerant can be distributed evenly by the condenser 2 as described above.
- Embodiment 1 employs an evenly distributing unit that evens out the refrigerant distribution among the refrigerant paths of the condenser 2 even if waste heat is recovered from the discharge gas refrigerant that is discharged from the compressor 1. Therefore, the deterioration in the performance of the refrigerator 100 can be assuredly avoided. Furthermore, since the waste heat recovered from the discharge gas refrigerant can be efficiently utilized, high energy-saving performance can be provided all year round.
- Fig. 7 is a diagram illustrating a configuration of a refrigeration cycle apparatus according to Embodiment 2 of the present invention. Embodiment 2 will now be described, focusing on differences from Embodiment 1.
- Embodiment 1 concerns a configuration in which the distributor 22 is provided on the downstream side of the waste-heat heat exchanger 5
- Embodiment 2 concerns a configuration in which the distributor 22 is provided on the upstream side of the waste-heat heat exchanger 5, that is, between the waste-heat heat exchanger 5 and the compressor 1.
- the distributor 22 corresponds to the evenly distributing unit and distributes the refrigerant on the upstream side of the waste-heat heat exchanger 5.
- the distributor 22 is the header illustrated in Fig. 2 .
- the refrigerant flowing into the distributor 22 turns into a state of single-phase gas without fail. Hence, there is no chance that the refrigerant that is in a state of two-phase gas-liquid is distributed, and the refrigerant can assuredly be distributed evenly by the header used as the distributor 22.
- the waste-heat heat exchanger 5 may be configured such that pipes through which distributed portions of the refrigerant flow, respectively, and pipes through each of which water flows are in contact with each other for heat exchange.
- highly efficient heat exchange can be achieved with a compact waste-heat heat exchanger 5 even if the waste-heat heat exchanger 5 is configured such that water exchanges heat with all of the distributed portions of the refrigerant.
- Embodiment 2 produces not only the advantageous effect produced in Embodiment 1 but also the advantageous effects produced in the case of single-phase distribution (assuredly even) and in the case of two-phase distribution (no limitations on the amount of waste heat exchanged).
