Wherein, compressor 1 has exhaust outlet a and gas returning port b, and compressor 1 compresses for the refrigerant flowed into by gas returning port b, forms HTHP cold media gas and discharge from exhaust outlet a after refrigerant compression.Commutation assembly 2 has the first port c to the 4th port f, first port c is communicated with one of them in the 3rd port e with the second port d, 4th port f and the second port d are communicated with another in the 3rd port e, and the first port c is connected with exhaust outlet a, and the 4th port f is connected with gas returning port b.That is, commutation assembly 2 has two kinds of conducting states, a kind of conducting state is the first port c and the second port d conducting and the 3rd port e and the 4th port f conducting, and another kind of conducting state is the first port c and the 3rd port e conducting and the second port d and the 4th port f conducting.The first end g of outdoor heat exchanger 3 is connected with the second port d, and the first end h of indoor heat exchanger 4 is connected with the 3rd port e, is in series with restricting element 5 between the second end i of outdoor heat exchanger 3 and the second end j of indoor heat exchanger 4.
Particularly, compressor 1, commutation assembly 2, outdoor heat exchanger 3, indoor heat exchanger 4 and restricting element 5 limit for the refrigerant that circulates kind of refrigeration cycle passage and heat circulation canal, namely heating and air conditioner 10 has refrigeration and the function that heats.
When indoor environment needs cooling, commutation assembly 2 controls the first port c and the second port d conducting, and the 3rd port e and the 4th port f conducting, compressor 1, commutation assembly 2, outdoor heat exchanger 3, indoor heat exchanger 4 and restricting element 5 form the kind of refrigeration cycle passage of refrigerant.In kind of refrigeration cycle passage, refrigerant flows to as shown in arrow A in Fig. 1, refrigerant is discharged from exhaust outlet a after being compressed into HTHP cold media gas by compressor 1, the refrigerant of discharging flows to outdoor heat exchanger 3 from commutation assembly 2, HTHP cold media gas is condensation heat release in outdoor heat exchanger 3, refrigerant in outdoor heat exchanger 3 flows to restricting element 5 again with reducing pressure by regulating flow, the refrigerant flowed out from restricting element 5 flows to indoor heat exchanger 4 again with the cold media gas of evaporation endothermic formation low-temp low-pressure, thus room air is freezed, refrigerant in last indoor heat exchanger 4 flows back to the gas returning port b of compressor 1 again by commutation assembly 2.
When indoor environment needs to heat up, commutation assembly 2 controls the first port c and the 3rd port e conducting, and the second port d and the 4th port f conducting, what compressor 1, commutation assembly 2, outdoor heat exchanger 3, indoor heat exchanger 4 and restricting element 5 formed refrigerant heats circulation canal.Heating in circulation canal, refrigerant flows to as indicated by arrow b of figure, refrigerant is discharged from exhaust outlet a after being compressed into HTHP cold media gas by compressor 1, the refrigerant of discharging flows to indoor heat exchanger 4 from commutation assembly 2, HTHP cold media gas is condensation heat release in indoor heat exchanger 4, thus room air is heated, refrigerant in indoor heat exchanger 4 flows to restricting element 5 again with reducing pressure by regulating flow, the refrigerant flowed out from restricting element 5 flows to outdoor heat exchanger 3 again with the cold media gas of evaporation endothermic formation low-temp low-pressure, refrigerant in outdoor heat exchanger 3 flows back to the gas returning port b of compressor 1 again by commutation assembly 2.
Preferably, because the application technology of cross valve 21 in air-conditioning equipment is comparatively ripe, and the volume of cross valve 21 is little, cost is lower, and commutation function is stable, reliable, and cross valve 21 selected by the assembly 2 that therefore commutates.Certainly, the present invention is not limited thereto, such as, commutation assembly 2 also to can be disclosed in prior art by multiple control valve also, valve member in series, do not do concrete restriction here.Alternatively, restricting element 5 is capillary, and thus, restricting element 5 cost is lower, and installation site is more flexible.
It should be noted that, the structure, principle etc. of compressor 1, cross valve 21, outdoor heat exchanger 3, indoor heat exchanger 4 and restricting element 5 are prior art, are just not described in detail here.
With reference to Fig. 1-Fig. 3, the first refrigerant flow L1 and the second refrigerant flow L2 is connected between the second end i of outdoor heat exchanger 3 and restricting element 5 respectively.Electric radiator assembly 6 comprises electric control element 62 and the radiating subassembly 61 for dispelling the heat to electric control element 62, radiating subassembly 61 is connected on the first refrigerant flow L1, first check valve 7 to be connected on the first refrigerant flow L1 and at the second end i of heat exchanger 3 outdoor to one-way conduction on the direction of radiating subassembly 61, the second check valve 8 to be connected on the second refrigerant flow L2 and on the direction of the second end i from restricting element 5 to outdoor heat exchanger 3 one-way conduction.Alternatively, as shown in Figure 1, the first check valve 7 is connected between outdoor heat exchanger 3 and radiating subassembly 61.
That is, refrigerant circulation duct between second end i of outdoor heat exchanger 3 and restricting element 5 is divided into two branch roads in parallel by three-way pipe, wherein a branch road is the first refrigerant flow L1, radiating subassembly 61 due to electric radiator assembly 6 is connected on the first refrigerant flow L1, therefore, the refrigerant flowing through the first refrigerant flow L1 can carry out heat exchange with radiating subassembly 61.Due to the first check valve 7 that the first refrigerant flow L1 has connected, and the second check valve 8 that the second refrigerant flow L2 has connected, therefore, refrigerant in first refrigerant flow L1 and the second refrigerant flow L2 can only one-way flow, wherein, first refrigerant flow L1 conducting and not conducting when heating when heating and air conditioner 10 is freezed, namely the first refrigerant flow L1 is included in the kind of refrigeration cycle passage of refrigerant, second refrigerant flow L2 when heating and air conditioner 10 heats conducting and refrigeration time not conducting, namely the second refrigerant flow L2 is included in heating in circulation canal of refrigerant.
Specifically, when heating and air conditioner 10 is freezed, refrigerant flows to as shown in arrow A in Fig. 1, after compressor 1 runs, the refrigerant that compressor 1 is discharged first dispels the heat through outdoor heat exchanger 3, heat radiation after refrigerant temperature drop to close to or a little more than outdoor environment temperature, due to the first check valve 7 conducting on kind of refrigeration cycle direction, second check valve 8 not conducting, therefore the refrigerant that outdoor heat exchanger 3 is discharged all flows to the first refrigerant flow L1, refrigerant in first refrigerant flow L1 absorbs heat when flowing through radiating subassembly 61, thus cooling is carried out to electric control element 62, refrigerant afterwards in the first refrigerant flow L1 flows to indoor heat exchanger 4 through restricting element 5 again and absorbs heat.And because the second check valve 8 not conducting is to ensure that refrigerant all flows to the first refrigerant flow L1, cold medium flux is comparatively large, thus the first refrigerant flow L1 can reach the object of lowering the temperature to electric control element 62 preferably.
When heating and air conditioner 10 heats, refrigerant flows to as indicated by arrow b of figure, after compressor 1 runs, owing to heating the first check valve 7 not conducting on loop direction, the second check valve 8 conducting, therefore the refrigerant that restricting element 5 is discharged all flows to the second refrigerant flow L2, avoid the excessive drop temperature to electric control element 62, also prevent the generation of condensed water on electric radiator assembly 6, thus ensure that the reliability of electric control element 62.Afterwards, the refrigerant in the second refrigerant flow L2 flows to outdoor heat exchanger 3 and absorbs heat.
It should be noted that, the electric control element 62 in electric radiator assembly 6 can be the control assembly of any needs heat radiation in heating and air conditioner 10, does not do concrete restriction here.When environment temperature is higher, heating and air conditioner 10 needs refrigeration usually, under hot environment, radiating subassembly 61 is not good by the radiating effect of natural convection air, therefore radiating subassembly 61 is connected on the first refrigerant flow L1, the radiating effect of electric control element 62 can be improved, ensure electric control element 62 functional reliability in high temperature environments.And when the temperature of the surroundings is low, heating and air conditioner 10 needs to heat usually, and under low temperature environment, radiating subassembly 61 just can reach good radiating effect by natural convection air, therefore, when heating and air conditioner 10 heats, refrigerant can not carry out forced heat radiation to radiating subassembly 61.
In a concrete example, heating and air conditioner 10 is transducer air conditioning, electric control element 62 in electric radiator assembly 6 is outdoor automatically controlled frequency-variable module, by being connected on the first refrigerant flow L1 by the radiating subassembly 61 of automatically controlled for outdoor frequency-variable module, solve the heat dissipation problem of outdoor automatically controlled frequency-variable module well.
And inventor finds through experiment, under same service condition, radiating subassembly 61 to be connected on the first refrigerant flow L1 for not being connected on the first refrigerant flow L1, the temperature of outdoor automatically controlled frequency-variable module can reduce by more than 15 DEG C, the frequency of compressor 1 hot operation can improve 20HZ, the comparable common frequency changer of high-temperature refrigeration amount during outdoor temperature more than 35 DEG C improves more than 10%, and high-temperature refrigeration amount during outdoor temperature more than 45 degree can improve more than 20%.It can thus be appreciated that after the radiating effect raising of electric control element 62, electric control element 62 service behaviour in high temperature environments promotes greatly.
According to the heating and air conditioner 10 of the embodiment of the present invention, by arranging the first refrigerant flow L1 and the second refrigerant flow L2 that are connected in parallel between outdoor heat exchanger 3 and restricting element 5, radiating subassembly 61 in electric radiator assembly 6 is connected on the first refrigerant flow L1, and the first refrigerant flow L1 and the second refrigerant flow L2 is respectively equipped with the first check valve 7 and the second check valve 8, during to make kind of refrigeration cycle, refrigerant all flows through the first refrigerant flow L1, thus electric radiator assembly 6 is dispelled the heat, and then improve the service behaviour of electric control element 62.And refrigerant is carrying out heating circulation time first refrigerant flow L1 not conducting, thus avoid refrigerant to electric control element 62 excessive drop temperature, prevent from electric radiator assembly 6 produces condensed water, and then ensure the reliability of electric control element 62.
In certain embodiments, as shown in Figures 2 and 3, radiating subassembly 61 is positioned at the below of electric control element 62 and contacts with electric control element 62, like this, radiating subassembly 61 can support electric control element 62, avoid electric control element 62 stress deformation or damage, radiating subassembly 61 contacts the heat that can ensure electric control element 62 and is passed to radiating subassembly 61 as much as possible and sentences heat radiation with electric control element 62, improve the radiating efficiency of electric control element 62.
Particularly, as shown in Figures 2 and 3, radiating subassembly 61 comprises: radiating tube 611 and radiation shell 612, and radiating tube 611 is connected on the first refrigerant flow L1, radiating tube 611 is located on radiation shell 612, and radiation shell 612 contacts with electric control element 62 and is used for dispelling the heat to electric control element 62.Here, the setting of radiating tube 611 ensure that refrigerant can flow through radiating subassembly 61 with radiating subassembly 61 heat exchange, the setting of radiation shell 612 is used for fixing radiating tube 611 and for heat transfer.
More specifically, radiation shell 612 comprises heat-radiating substrate 6121 and fixed dam 6122, heat-radiating substrate 6121 contacts with electric control element 62, and fixed dam 6122 is located on heat-radiating substrate 6121, limits the spatial accommodation V for holding radiating tube 611 between fixed dam 6122 and heat-radiating substrate 6121.Here, fixed dam 6122 is for supporting radiating tube 611, and heat-radiating substrate 6121 coordinates to fix, protect radiating tube 611 with fixed dam 6122, and facilitates the assembling of radiating tube 611 and radiation shell 612.Wherein, heat-radiating substrate 6121 contacts with electric control element 62, and the heat of electric control element 62 is directly passed to radiating tube 611 place by heat-radiating substrate 6121, thus ensures that electric control element 62 dispels the heat well.
Advantageously, the shape of spatial accommodation V is identical with the shape of radiating tube 611, thus is convenient to the installation location of radiating tube 611.And, when the cross-sectional area of spatial accommodation V is equal with the cross-sectional area of the corresponding position of radiating tube 611, thus form face closely between radiating tube 611 and the internal perisporium of spatial accommodation V and contact and coordinate, thus ensure that the heat-transfer effect between radiation shell 612 and radiating tube 611 is good.
