First embodiment
Referring to FIG. 2, the embodiment of the invention provides a kind of heat-production control methods.The heat-production control method can be applied to
Multi-online air-conditioning system 1.As shown in Fig. 2, above-mentioned heat-production control method may comprise steps of:
Step S101 obtains temperature collecting cell acquisition when detecting that multi-online air-conditioning system is operated with sub-load
Outdoor environment temperature.
In embodiments of the present invention, when outdoor environment temperature is lower, for example, user needs empty using multi-connected machine when winter
Adjusting system 1 is heated, when multi-online air-conditioning system 1 is in heating mode, need to detect multi-online air-conditioning system 1 whether portion
Divide load running, if detecting that sub-load operates multi-online air-conditioning system 1 in a heating mode, acquisition is set to outdoor
The outdoor environment temperature that temperature collecting cell 2 on machine acquires.
In embodiments of the present invention, detection multi-online air-conditioning system 1 whether sub-load operating method may include with
Lower three kinds:
Whether the first judges all indoor units when detecting that multi-online air-conditioning system 1 reaches target fan-out capability
It is in starting state, if only part indoor unit is in starting state, determines that 1 sub-load of multi-online air-conditioning system is transported
Turn；
Second, when detecting that multi-online air-conditioning system 1 reaches target fan-out capability, judge outdoor unit revolving speed whether
Reach outdoor unit maximum setting speed, if the revolving speed of outdoor unit does not reach outdoor unit maximum setting speed, determines multi-connected machine

Then, when outdoor environment temperature is greater than the first preset threshold, that is, as Tao > A, if booting indoor unit load
Rate is greater than or equal to default indoor unit rate of load condensate, that is, if LOR>=y, then adjusting target condensation temperature is the first temperature, optionally,
First temperature is [48 DEG C, 51 DEG C]；If the indoor unit rate of load condensate that is switched on is less than default indoor unit rate of load condensate, that is, if LOR< y, then adjust
Target condensation temperature is second temperature, and optionally, second temperature is [51 DEG C, 54 DEG C].
Further, when outdoor environment temperature is less than or equal to the first preset threshold and is greater than the second preset threshold, that is,
As B < Tao≤A, if booting indoor unit rate of load condensate is greater than or equal to default indoor unit rate of load condensate, that is, if LOR>=y, then adjust
Target condensation temperature is second temperature, and optionally, second temperature is [51 DEG C, 54 DEG C]；If the indoor unit rate of load condensate that is switched on is less than pre-
If indoor unit rate of load condensate, that is, if LOR< y, then adjust target condensation temperature be third temperature, optionally, third temperature be [54 DEG C,
57℃]。
Further, when outdoor environment temperature is less than or equal to the second preset threshold, that is, as Tao≤B, if booting
Indoor unit rate of load condensate is greater than or equal to default indoor unit rate of load condensate, that is, if LOR>=y, then adjusting target condensation temperature is third temperature
Degree, optionally, third temperature are [54 DEG C, 57 DEG C]；If the indoor unit rate of load condensate that is switched on is less than default indoor unit rate of load condensate, that is, if
LOR< y, then adjusting target condensation temperature is the 4th temperature, and optionally, the 4th temperature is [57 DEG C, 60 DEG C].
Step S104, the compressor for controlling multi-online air-conditioning system are gone up and down according to target condensation temperature adjusted
Frequently.

Influence of the sound size to user, on demand after the target condensation temperature of segmentation adjustment multi-online air-conditioning system 1, control multi-connected machine is empty
The compressor 3 of adjusting system 1 carries out lifting frequency according to target condensation temperature adjusted.
Therefore, as outdoor environment temperature Tao > A, when, if booting indoor unit rate of load condensate LOR>=y then controls compressor 3 and presses
According to target condensation temperature TCtar=[48 DEG C, 51 DEG C] lifting frequency, if booting indoor unit rate of load condensate LOR< y then controls compressor 3 and presses
According to target condensation temperature TCtar=[51 DEG C, 54 DEG C] lifting frequency；As outdoor environment temperature B < Tao≤A, if booting indoor unit
Rate of load condensate LOR>=y then controls compressor 3 according to target condensation temperature TCtar=[51 DEG C, 54 DEG C] lifting frequency, if booting indoor unit
Rate of load condensate LOR< y then controls compressor 3 according to target condensation temperature TCtar=[54 DEG C, 57 DEG C] lifting frequency；When outdoor environment temperature
When spending Tao≤B, if booting indoor unit rate of load condensate LOR>=y then controls compressor 3 according to target condensation temperature TCtar=[54 DEG C,
57 DEG C] lifting frequency, if booting indoor unit rate of load condensate LOR< y then controls compressor 3 according to target condensation temperature TCtar=[57 DEG C,
