Specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of varying capacity one drags many control technologys, comprise and have the control assembly that varying capacity one drags many central air conditioner systems and has the control logic of distribution of control refrigerant and energy adjustment, described central air conditioner system comprises an off-premises station 1, at least two indoor sets 2, at least one intermediate energy distributor disk 3 and refrigerant pipes therebetween, and described control assembly comprises at least one outdoor controller, at least two indoor set controllers, at least one middle controller, at least two indoor controllers and the corresponding control circuits that connect thereof; The indoor set controller can and middle controller and indoor controller between mutually communication; And that the indoor set controller has is cold soon/fast hot merit energy;
Off-premises station 1 has at least one and heats with electric expansion valve and at least one variable conpacitance compressor; The output of the energy of variable conpacitance compressor is controlled by the parameter of the signal of corresponding indoor demand and environment, protection; The degree of superheat when electric expansion valve of off-premises station 1 can heat according to the temp probe adjusting of off-premises station 1 coil pipe import, centre, outlet;
Intermediate energy distributor disk 3 includes at least two cooling electric expansion valves, at least two and heats with magnetic valve and a middle controller; Intermediate energy distributor disk 3, in the middle of it controller can and outdoor controller and indoor set controller between communication mutually, its refrigerating/heating electric expansion valve and magnetic valve can control to adjust according to indoor set 2 coil pipe imports, centre, the temp probe of outlet and the signal of indoor demand; Indoor set 2 coil pipes are equipped with the temp probe and the indoor return air temperature probe of import, centre, outlet;
The control logic of control assembly has energy control logic and degree of superheat control logic, and also has cold soon/fast thermal control logic; The energy control logic can be determined the energy rank of indoor set 2 according to the temperature difference of return air temperature and design temperature, determining required refrigeration work consumption, and can export according to energy-the compressor variable capacity relationship determines compressor output; Degree of superheat control logic can be regulated electric expansion valve according to the temperature difference of evaporator outlet and import or medium temperature.
As shown in Figure 2, indoor controller is accepted user instruction (start/shutdown, refrigerating/heating/ventilation, design temperature, whether cold soon/fast heat), send to outdoor controller together with indoor set 2 temperature signals by middle controller, outdoor controller draws the compressor power output by compressor frequency/capacity module, as indoor set 2 required rates altogether is 6kw, and then given compressor frequency is 60HZ.And regulate the switch of electronic expansion valve opening and magnetic valve by off-premises station 1 and indoor set 2 coil temperatures, as the electric expansion valve of regulating No. two indoor set correspondences makes the difference of its coil pipe outlet temperature and inlet temperature less than twice greater than once.When many indoor sets were opened simultaneously, the electric expansion valve of different indoor set correspondences was regulated voluntarily automatically according to the instruction of off-premises station 1, thus the reasonable distribution of regulating refrigerant.Also monitoring and calculating energy demand are carried out energy adjustment to off-premises station 1 in real time.As the pairing indoor design temperature that reaches of machine in certain, then compressor frequency is corresponding reduces.
As shown in Figure 3, outdoor controller can be monitored various protections and fault in real time, carries out various processing; as system overload, then compressor is corresponding carries out frequency reducing even shuts down, and takes place if any fault; then send the corresponding failure code on indoor and controller, carry out troubleshooting.
Though the present invention illustrates and describes by preferred embodiment,, those skilled in the art should understand, and in claim of the present invention institute restricted portion, can carry out various variations in form and details.
