Following examples solve and regulate and control to solve the unmatched problem of indoor heat-exchanger rig power by outdoor heat exchange device.
Wherein, with the first indoor heat-exchanger rig 10 operations heat, the second indoor heat-exchanger rig 20 running refrigerating patterns illustrate, when the refrigeration work consumption of the second indoor heat-exchanger rig 20 is greater than the power that the first indoor heat-exchanger rig 10 heats, can select to open the first outdoor heat exchange device 60 or the second outdoor heat exchange device 80 and compensate the required refrigerant of the second indoor heat-exchanger rig 20 refrigeration, its operation stroke is as follows:
The refrigerant ejecting from the refrigerant exit A1 of compressor 100 first enters from the first end a of the first converter valve 30, control after the first converter valve 30 conductings, refrigerant flows out from the second end b of the first converter valve 30, and enter from the first end B1 of the first indoor heat-exchanger rig 10, refrigerant goes out from the second end B2 of the first indoor heat-exchanger rig 10 after the first indoor heat-exchanger rig 10 heat exchange; From the second end B2 of the second indoor heat-exchanger rig 20, enter, after the second indoor heat-exchanger rig 20 heat exchange, refrigerant goes out from the first end B1 of the second indoor heat-exchanger rig 20, then from the second end b of the second converter valve 40, enter, from the 3rd end c of the second converter valve 40, go out, then get back to compressor 100 from the refrigerant entrance A2 of compressor 100.
Now, when if find, the heating capacity of the first indoor heat-exchanger rig 10 can not meet the refrigerating capacity of the second indoor heat-exchanger rig 20, the present embodiment selects to open the first outdoor heat exchange device 60, the refrigerant ejecting from the refrigerant exit A1 of compressor 100 also enters from the first end a of the first interchangeable valve 70, control after the first interchangeable valve 70 conductings, refrigerant flows out from the second end b of the first interchangeable valve 70, and enter from the first end C1 of the first outdoor heat exchange device 60, refrigerant second end C2 from the first outdoor heat exchange device 60 after the first outdoor heat exchange device 60 heat exchange goes out; And flow in the capillary between the second end B2 of the first indoor heat-exchanger rig 10 and the second end B2 of the second indoor heat-exchanger rig 20, and the refrigerant flowing out with the second end B2 from the first indoor heat-exchanger rig 10 mixes, flow in the lump the second indoor heat-exchanger rig 20, for the second indoor heat-exchanger rig 20, freeze.
And when the refrigeration work consumption of the second indoor heat-exchanger rig 20 is less than the power that the first indoor heat-exchanger rig 10 heats, also can select to open the first outdoor heat exchange device 60 or the second outdoor heat exchange device 80, now need to not carry refrigerant to the first outdoor heat exchange device 60 or the second outdoor heat exchange device 80 from compressor 100, only remaining refrigerant (the first indoor heat-exchanger rig 10 heats the unnecessary refrigerant of rear discharge) after the second indoor heat-exchanger rig 20 refrigeration need be back to compressor through the first outdoor heat exchange device 60 or the second outdoor heat exchange device 80.Thereby realized by outdoor heat exchange device and regulated and controled to solve the unmatched problem of indoor heat-exchanger rig power.
When indoor heat-exchanger rig is many, for making full use of the ability of indoor heat-exchanger rig, can not need the regulation and control of outdoor heat exchange device, each indoor heat-exchanger rig of direct regulation and control just can solve the unmatched problem of each indoor heat-exchanger rig power.Three the indoor heat-exchanger rigs of for example take are example, when wherein one open refrigeration, open for one and heat, one when idle, if the indoor heat-exchanger rig power of refrigeration is greater than the power of the indoor heat-exchanger rig heating, can opens idle indoor heat-exchanger rig and carry out balance.
Control when in addition, a certain outdoor heat exchange device need to defrost is as follows:
For example, when opening in advance the first outdoor heat exchange device 60 and providing refrigerant to freeze to the first indoor heat-exchanger rig 10 or the second indoor heat-exchanger rig 20, now, if the second outdoor heat exchange device 80 need to defrost, can close the first outdoor heat exchange device 60, open the second outdoor heat exchange device 80 provides refrigerant to use to the first indoor heat-exchanger rig 10 or the second indoor heat-exchanger rig 20 simultaneously.Particularly, opening in advance the first outdoor heat exchange device 60 provides refrigerant to freeze to the first indoor heat-exchanger rig 10, and the operation stroke when switching to the second outdoor heat exchange device 80 and defrosting is: the refrigerant ejecting from the refrigerant exit A1 of compressor 100 first enters from the first end a of the first converter valve 30, control after the first converter valve 30 conductings, refrigerant flows out from the second end b of the first converter valve 30, and enter from the first end C1 of the first outdoor heat exchange device 60, refrigerant second end C2 from the first outdoor heat exchange device 60 after the first outdoor heat exchange device 60 heat exchange goes out; Then from the second end B2 of the first indoor heat-exchanger rig 10, enter, after the first indoor heat-exchanger rig 10 heat exchange, refrigerant goes out from the first end B1 of the first indoor heat-exchanger rig 10, then from the second end b of the first converter valve 30, enter, from the 3rd end c of the first converter valve 30, go out, then get back to compressor 100 from the refrigerant entrance A2 of compressor 100.
When finding that the second outdoor heat exchange device 60 need to defrost, close the first outdoor heat exchange device 60, open the second outdoor heat exchange device 80 simultaneously and carry out high wind refrigeration, now, the refrigerant ejecting from the refrigerant exit A1 of compressor 100 only enters from the first end a of the second converter valve 30, control after the second converter valve 30 conductings, refrigerant flows out from the second end b of the second converter valve 30, and enter from the first end C1 of the second outdoor heat exchange device 80, refrigerant second end B2 from the second indoor heat-exchanger rig 80 after the second outdoor heat exchange device 80 heat exchange goes out; From the second end B2 from the first indoor heat-exchanger rig 10 then, enter again, for the first indoor heat-exchanger rig 10 refrigeration.Wherein, the second outdoor heat exchange device 80 is meeting heat radiation heat in the process of carrying out sweat cooling, thereby has realized the operation of defrosting.
Below illustrate by way of example that each indoor heat-exchanger rig of each outdoor heat exchange device freezes and the concrete distribution of heating capacity (power) (for example, outdoor heat exchange device is 2,15 every, indoor heat-exchanger rig is 6,5 every, be that outdoor heat exchange device is 30, indoor heat-exchanger rig is also 30):
When indoor heat-exchanger rig have two open heat, four open when refrigeration, according to capacity calculation mode 5*2-5*4=-10,10≤15 and for negative, now need out an outdoor heat exchange device to heat, simultaneously according to the running temperature of the outdoor heat exchange device of opening, regulate the rotating speed of fan to carry out the power match of heat-exchanger rig and outdoor heat exchange device in balance cylinder.
When indoor heat-exchanger rig have three open heat, three open when refrigeration, according to capacity calculation mode 5*3-5*3=0, now do not need out outdoor heat exchange device.If need to outdoor heat exchange device be defrosted, can open that outdoor heat exchange device that needs defrosting, and turn off three and driven the indoor heat-exchanger rig heating.
When indoor heat-exchanger rig have four open heat, two open when refrigeration, according to capacity calculation mode 5*4-5*2=10,10≤15 and for just, now only need to open an outdoor heat exchange device and freeze, according to the running temperature of the outdoor heat exchange device of opening, regulate the rotating speed of fan to carry out the power match of heat-exchanger rig and outdoor heat exchange device in balance cylinder simultaneously.
By above control, not only can economize on resources, there is the situation of phase mutual interference in each pattern that can also prevent each indoor heat-exchanger rig and each outdoor heat exchange device.
