Description
Technical field
The present invention relates to a kind of heat pump of processing utensil for clothing, it comprises compressor, condenser, current limiter and evaporimeter, and also comprise liquid suction heat exchanger, wherein, described liquid suction heat exchanger comprises the first refrigerant line and the second refrigerant pipeline of thermal coupling each other; The import of the first refrigerant line of heat exchanger is attached to the outlet of evaporimeter, and the outlet of the first refrigerant line is attached to the import of compressor; And the import of second refrigerant pipeline is attached to the outlet of condenser, and the outlet of second refrigerant pipeline is attached to the import of current limiter.The invention still further relates to a kind of clothing processing utensil that comprises this heat pump.
Background technology
A kind of heat pump is processed utensil with the clothing that comprises this heat pump and is disclosed in EP 2 385 169A1.In being disclosed in heat pump there, additional heat exchanger is provided, in stream of ambient air and from heat-shift between condenser cold-producing medium out, and for from cold-producing medium out of condenser and from heat-shift between evaporimeter cold-producing medium out.This heat exchanger is included in the additional interaction of arriving the operation of heat pump between heat pump and surrounding environment thereof, thereby makes the operation of heat pump quite be difficult to process.The variation of environment temperature causes the variation of the operation operating mode of heat pump.
Compare with only adopting traditional clothesdrier of electric heater, comprise that the clothesdrier of heat pump has the efficiency of raising (in kWh/kg).Therefore, compare with conventional dryer, comprise that the associative operation CO2 emission of clothesdrier of heat pump is lower substantially due to its lower power consumption.Yet the GWP of the cold-producing medium using in heat pump (" global warming potential ") must be considered.Now, the typical cold-producing medium using in heat pump is GWP higher than 1500 fluorinated hydrocarbon (HFC).
In air path or processing air loop, process air and flow to evaporimeter from cylinder.At drum outlet place, air is under moderate temperature and relatively wet.At evaporimeter place, air is cooled and dehumidifies, and then flows to condenser, and air is heated at condenser place.Heated dry air and then be introduced in cylinder the clothing absorbing moisture that can hold at cylinder place heated dry air from cylinder.
Evaporimeter and condenser be fin-tube type normally.The pipe of evaporimeter and condenser can be separated individuality (as described in prior art document WO 2008/004802 A3, EP 2 261 416 A1 and EP 1 593 770B1), maybe can be connected in (as described in prior art document WO 2008/004802 A3) in same core.
Another typical construction of evaporimeter and condenser is so-called aluminium single hose (frost-free type), wherein, aluminum pipe be bent and in the situation that not there is not enlargement of pipe fin along aluminum pipe, place.
The overall diameter of the evaporimeter using in heat pump drier at present and the pipe of condenser is as follows: for Fin and tube evaporator and condenser, be 3/8 " (9.525mm) and 7mm, and be 8mm for aluminium single hose evaporimeter and condenser.
A possibility that reduces the TEWI (" warm and affect total yield ", it comprises directly and discharge indirectly) of these systems is to use the low hydrocarbon refrigerant of GWP, as R-290 (propane) or R-1270 (propylene).The major defect of these cold-producing mediums is that they are inflammable, so the maximum charge amount (150g) in IEC 60335-2-11 criteria limit clothesdrier.Conventionally be known that for particular system and can there is best refrigerant charge amount, but the fixed 150g cold-producing medium restriction of IEC 60335-2-11 standard is usually less than the best charge amount of cold-producing medium for the heat pump of clothesdrier.
The cloth drying utensil with heat pump generally includes refrigerant loop and air path.Flow of refrigerant is by compressor, condenser, current limiter and evaporimeter, with this order.These elements are by refrigerant line, especially pipeline communication.Cold-producing medium by means of condenser by thermal release to the processing air that flows through air path, and by means of evaporimeter from flowing through processing absorption of air heat and the moisture of air path.Compressor absorbs the cold-producing medium in energy compressed refrigerant loop.
Liquid suction heat exchanger (being also referred to as liquid-suction heat exchanger (liquid-to-suction heat exchanger) or regenerator) is mainly known in using in the cryogenic refrigerating system of the steam compression system between evaporimeter and compressor with long distance.Liquid suction heat exchanger generally includes two refrigerant lines or passage (for example pipeline), wherein, the liquid refrigerant that flows in one (" liquid " pipeline) in described refrigerant line, and in another refrigerant line (" suction " pipeline), flow into the cold-producing medium of vapor form.Described pipeline is thermally coupled to allow the heat transmission between them and conventionally to isolate with respect to surrounding environment heat each other.Liquid suction heat exchanger can improve cooling capacity and reduce the power in input steam compression system some cold-producing medium.For refrigeration system, liquid suction heat exchanger can be with the evaporating temperature lower than zero degrees celsius (corresponding to the evaporator outlet temperature of about-20 ℃) work.Therefore, in suction pipeline due to high temperature difference (between cold-producing medium and surrounding air) produce outside overheated.Overheated COP (the coefficient of performance that has reduced heat pump in this outside; Cooling capacity is inputted divided by power) because compressor power consumption increase does not but affect cooling capacity.Liquid suction heat exchanger is rarely used in air-conditioning system, because the pressure drop that liquid suction heat exchanger is introduced has obviously reduced its benefit for air-conditioning system.
Summary of the invention
An object of the present invention is to overcome at least in part to comprising the clothing of heat pump and process at least some problem of the prior art that utensil is relevant, and a kind of GWP and high efficiency heat pump reducing that have of processing utensil for clothing is especially provided.
This object realizes by the feature of independent claims.Preferred embodiment is especially proposed by dependent claims.
This object realizes by a kind of heat pump for clothing processing utensil, described heat pump comprises compressor, condenser, current limiter and evaporimeter, and also comprise liquid suction heat exchanger, wherein, described liquid suction heat exchanger comprises the first refrigerant line and the second refrigerant pipeline of thermal coupling each other; The import of the first refrigerant line of heat exchanger is attached to the outlet of evaporimeter, and the outlet of the first refrigerant line is attached to the import of compressor; And the import of second refrigerant pipeline is attached to the outlet of condenser, and the outlet of second refrigerant pipeline is attached to the import of current limiter.In addition, the first refrigerant line and second refrigerant pipeline are with respect to the surrounding environment heat isolation of liquid suction heat exchanger.
This object is also processed utensil by a kind of clothing that comprises heat pump and is realized, and wherein, this heat pump is heat pump as above.
The advantage that additional use that clothing is processed the liquid suction heat exchanger in utensil provides in evaporimeter the possible enthalpy of the refrigerant inlet place of evaporimeter (especially) to increase by heat-shift between the cold-producing medium part in the different sections of heat pump.This measure only relates to the inner parameter of heat pump, and has avoided any obvious interaction with the surrounding environment of heat pump.Even if therefore increased stability and reliability in the operation situation that the relevant parameter of environment changes around.
Another advantage is to reduce refrigerant mass fluxes.Therefore, cold-producing medium in the temperature of compressor inlet due to extra overheated the increasing in liquid suction heat exchanger.Therefore, cold-producing medium reduces in the density of compressor inlet, thereby causes the power consumption of compressor to reduce.In particular, if comprise that the heat pump of liquid suction heat exchanger is operated in (it is overheated to show in evaporimeter) under its best operating point, the cooling capacity in evaporimeter increases (because the impact that enthalpy increases is greater than the impact that mass flow reduces) and power consumption reduction, thereby has realized identical compression ratio.Therefore, dehumidifying speed increases, and power consumption reduces.This means the drying time of dry run and reduce energy consumption.And the increase of the cooling capacity in evaporimeter has improved COP, especially for hydrocarbon refrigerant.
Another advantage is that a side of the first refrigerant line of heat exchanger (suction pipeline) is attached to the outlet of evaporimeter, and the opposite side of the first refrigerant line is attached to the import of compressor; And further, a side of second refrigerant pipeline (liquid line) is attached to the outlet of condenser, and the opposite side of second refrigerant pipeline is attached to the import of current limiter.In particular, such connection makes the heat exchanger can the cooling cold-producing medium from condensator outlet (applying more excessively cold) and heating fumigators outlet (it is how overheated to apply).
The described heat pump of described heat exchanger can use inflammable or non-flammable coolant.
Described heat exchanger can be different configuration (such as twin flue formula, as plate type heat exchanger etc.).
In a preferred embodiment of the invention, second (liquid) refrigerant line is compared higher with respect to the hot degree of isolation of surrounding environment with first (suction) refrigerant line.This has kept increasing in the temperature of compressor inlet.In twin flue design (wherein, the first pipeline is around second pipe) situation under, this design can be implemented in the following manner: use the first pipeline as first (suction) refrigerant line, and use second pipe as second (liquid) refrigerant line.Therefore, vaporous cold-producing medium mobile in the first pipeline experiences the lower temperature difference with respect to surrounding environment, and meanwhile, in second pipe, mobile liquid refrigerant is because it is experienced higher temperature difference by the first pipeline with respect to surrounding environment thermal protection.
In another preferred embodiment of the present invention, the discharge capacity of compressor is 12cc/rev (cubic centimetre often turns) or less, especially 10.5cc/rev or less.This embodiment reflects unexpected discovery: compressor displacement large (especially for common home appliances) in the situation that, may need to increase the heating efficiency at condenser place, to realize the dissipation of energy from compressor.In order to increase condenser capacity, and then need larger condenser area and volume.Therefore, also needing increases refrigerant charge amount, to realize the condensation of cold-producing medium in condenser.Yet this is difficult to defer to the charge amount restriction (150g) of IEC60335-2-11 standard to flammable coolant, and the best charge amount of the operating point for heat pump may be changed over further from (current) 150g and limits.
In another preferred embodiment of the present invention, the overall diameter of the overall diameter of condenser tubes (pipeline using with condenser) and/or evaporator pipeline (pipeline using with evaporimeter) is less than 7mm.This has reduced refrigerant loop volume, even and make also cooling refrigeration agent effectively low charge amount (being especially less than 150g) in the situation that, rely on liquid suction heat exchanger to keep high heat pump efficiency simultaneously.In particular, in order to make the cold-producing medium can condensation in condenser (using less refrigerant charge amount in condenser), it be preferred using the overall diameter that is less than 7mm.Therefore, can realize two positive roles: the suitable efficiency of excessively cold increase and liquid suction heat exchanger in condenser (on high-tension side additional mistake cold-peace in low-pressure side additional overheated) simultaneously.
In fact, pipeline (and especially pipeline) is measured and is characterized by their overall diameter, and described overall diameter is relevant to their interior diameter, and therefore relevant to the volume that can offer cold-producing medium.
In a particularly preferred embodiment of the present invention, the overall diameter of condenser tubes is less than 7mm, simultaneously the overall diameter of evaporator pipeline is 7mm or more greatly, for example 3/8 " (9.525mm), or for Fin and tube evaporator is 7mm and is 8mm for aluminium single hose evaporimeter.This embodiment has utilized: the refrigerant line of condenser (being also referred to as condenser coil) is the part (that is, larger volume and higher refrigerant density) that maximum refrigerant amount was amassed and therefore had to greatest content that has of refrigerant loop.The overall diameter that is less than 7mm by use, has reduced internal volume, thereby for the cold-producing medium of same quality, has just obtained higher density.This so mean, obtained the liquid refrigerant of the larger percentage in liquid-gas phase, thereby and then made the cold-producing medium can condensation quickly in condenser.Therefore, realized excessively cold greatly, and thereby useful to cooling capacity.
In another particularly preferred embodiment, the overall diameter of condenser tubes and/or the overall diameter of evaporator pipeline are about 6mm or less, especially 5mm or less.Approximately the overall diameter of 5mm is considered to be in the little charge amount of cold-producing medium and particularly preferred the trading off between high efficiency.
As a specific example, consider traditional 7mm condenser (thering is the condenser that overall diameter is the refrigerant tubing of 7mm) and use the contrast of 5mm condenser of the family expenses cylindrical drier of 150g propane (being also referred to as R290).These 5mm condensers are compared with 7mm condenser, and the volume of cold-producing medium is low by 12%.This 5mm condenser make to have reduced drying time 13% and reduce energy consumption 11%.For with 7mm condenser and adopt same drying time and high 4% energy consumption realizes similar drying property, need the R290 of 210g.
In addition, compare with the reference case of 7mm condenser (with 7mm evaporimeter), the combination of 5mm condenser and 5mm evaporimeter can provide additional improvement.Use 5mm condenser and 5mm evaporimeter make to have reduced drying time 16% and reduce energy consumption 14%.
In another preferred embodiment of the present invention, the cold-producing medium of heat pump is flammable coolant.This embodiment is by make the charge amount of cold-producing medium be 150g or still less become feasible.Flammable coolant is compared and is conventionally had lower GWP with non-flammable coolant.
In another preferred embodiment, described cold-producing medium comprises hydrocarbon refrigerant or multiple hydrocarbon refrigerant therein.Hydrocarbon refrigerant demonstrates and is low to moderate negligible GWP.Hydrocarbon refrigerant is being particularly useful aspect raising system COP for liquid suction heat exchanger.
Therein in a preferred embodiment, described cold-producing medium is or comprises propane (R290).The advantage that propane has is: GWP relatively low (being 3.3 times of GWP of carbon dioxide), do not damage the ozone layer, can be used as the substitute of R-12, R-22, R-134a and other chlorinations and/or fluorinated hydrocarbon and easily obtain.
Therein in an alternate embodiment, described cold-producing medium is or comprises propylene (R1270).
In another preferred embodiment, described cold-producing medium is or comprises HFO-1234yf or 2,3, and 3,3 tetrafluoeopropenes (2,3,3,3-Tetra-fluoropropene).HFO-1234yf can exert an influence to environment hardly, and comparing obtained GWP grade with traditional R-134a is 1/335th, and atmospheric lifetime is about 1/400th.In addition, HFO-1234yf is only inflammable slightly.
