On the outlet refrigeration working medium pipeline of compressor 1, compressor 2 20 pressure transmitter 1, pressure transmitter 2 22 are installed, the high pressure output signal is input to PLC Programmable Logic Controller 8, set value relatively back output signal with the refrigeration machine high pressure, cooling condition passes through the rotating speed of Frequency Converter Control axial flow blower 1, axial flow blower 26 respectively, when the compressor outlet high pressure surpasses setting value, rev up improves condensation efficiency, and high pressure is reduced; When the compressor outlet high pressure is lower than when setting value, reduce rotating speed, reduce condensation efficiency, high pressure is improved, controlled the outlet high pressure of compressor, also with regard to indirect control the temperature of life with hot water.During heating condition, the evaporimeter of source pump is condenser, therefore controls air conditioner water circulating pump 13, can control the outlet high pressure of compressor with this, in order to the control recuperation of heat water temperature and the air-conditioning water temperature in winter.Control the outlet high pressure of compressor, also protected compressor not produce fault.
PLC Controlled by Programmable Controller program as shown in Figure 1, unit starting, set refrigeration or heating condition earlier, compressor 1, compressor 2 20 runnings, the outlet high-voltage signal of the first cooling condition pressure transmitter 17, pressure transmitter 2 22 output compressors enters PLC Programmable Logic Controller 8, and PLC Programmable Logic Controller 8 is regulated its rotating speed by first frequency converter, the second Frequency Converter Control axial flow blower 1, axial flow blower 26; Heating condition is by frequency converter three control air conditioner water circulating pumps 13; regulate its rotating speed; thereby the high-pressure outlet pressure of control compressor; make it reach setting value, Here it is compressor high-pressure outlet pressure regulating system, the control outlet pressure is within range of set value; control the hot water temperature of recuperation of heat on the one hand; also protect the outlet high pressure of compressor to be no more than certain pressure on the other hand, make the normal failsafe of compressor operating, life-saving.
Is the refrigeration working medium of compressor outlet at first looked into Ran Huanhuang by second refrigeration working medium? 4 refrigeration working medium side, carry out heat exchange heating life hot water with hot water side, the hot water temperature enters the PLC Programmable Logic Controller by hot water temperature's transmitter 25 output signals of heat exchanger water side entrance, by the operation of its output signal control recuperation of heat circulating pump 26, reach control recuperation of heat hot water temperature's purpose.
In spring, autumn, when still needing life to use hot water in the building, air source heat pump recuperation of heat unit is replaced boiler operatiopn.On the air-conditioning water pipe, be provided with air conditioner water temperature transmitter 15, its output signal input PLC Programmable Logic Controller 8, with the setting value of refrigeration or heating condition relatively after, its output signal can be controlled the commutation action of four-way change-over valve 1 or four-way change-over valve 27.When two systems are cooling condition; when the air conditioner water temperature reaches below 7 ℃; before unit is not shut down; PLC Programmable Logic Controller output signal makes one of them system of four-way change-over valve convert thermal condition to; in order to improve the air-conditioning water temperature, unit is remained in operation, when the hot water temperature who measures up to hot water temperature's transmitter 25 and air conditioner water temperature transmitter 15 temperature value measured reach simultaneously and set value; PLC Programmable Logic Controller 8 all shuts down unit by just sending the signal of shutdown with door.Thermal condition also is same control procedure, and generally when the air-conditioning water temperature reached more than 45 ℃, the PLC Programmable Logic Controller sends signal made one of them system of four-way change-over valve convert cold operating mode to, makes the air conditioner water temperature drop low, thereby makes unit continue operation.Unit just can be worked as hot-water boiler at spring and autumn provides life hot water.
