After being condensed within the condenser, evaporator 40 is entered by the throttling action of electric expansion valve 31.Due to now whole machine heat exchange
Amount demand is big, and the control stream of electromagnetism Vavle switching second connects two evaporators 40, while exchanged heat, now machine system
Caloric receptivity reaches maximum.The demand of rapid heat hot water can be met.
Run in the case that the water temperature of water tank 70 is higher：
With the continuous rising of water temperature in water tank 70, when water temperature T 2 is higher than T1, because water temperature over-high will cause system
High pressure is raised, and compressor pressure ratio is excessive, the decay of compressor efficiency is serious.But now water temperature has reached routine use temperature, then
Logical complete machine control system controls the upper electricity of controlling organization 23, and now the electromagnetism part inside compressor is powered, and compression mechanism 22 is inhaled
Close, executing agency 21 is in idling conditions in compression chamber, does not carry out refrigerant compression.Only one of which compression unit 20 carries out cold
Matchmaker's compressed action.Now the capacity of compressor is a capacity for compression unit 20.By electric three passes Vavle switching first
Control stream, exchanges heat using only a condenser 30 to the hot water in water tank 70, continues to produce water temperature hot water higher, together
When electromagnetism Vavle switching second control stream, exchanged heat using only an evaporator 40.Machine system is set to keep relatively low heat exchange
Amount carries out water heating.Reduce due to the reduction of heat exchange amount, compressor displacement, compressor power consumption is equally reduced, so that whole function
Effect is than continuing to keep a preferably level run.
Air energy water heater system based on Fig. 1 to Fig. 3, present invention also offers a kind of control of air energy water heater system
Method processed.The control method includes：
Preset temperature value T1；
The temperature value T2 of the hot water to be added in detection air energy water heater system；
Compare the size of T1 and T2；
If T2 is less than T1, the first compression unit 20 and the second compression unit 20 is controlled to work simultaneously；
If T2 is more than or equal to T1, control the controlling organization 23 of the second compression unit 20 to work, disconnect second and compress
The compression mechanism 22 of unit 20 and the drive connection relation of executing agency 21, the executing agency 21 of the second compression unit 20 dallies.
When using, preset temperature value T1 is basic usable hot water temperature.When the temperature value T2 for detecting hot water to be added is low
When T1, as shown in figure 1, the control selection first flow path of valve 50, to allow and have respectively entered two from the refrigerant for stating the outflow of evaporator 40
Participate in heating in compression unit 20, two compression chambers suck cryogenic gaseous refrigerant from gas-liquid separator simultaneously, and by two
Compression chamber compresses jointly, and the actual displacement of compressor is two conjunctions of the discharge capacity of compression chamber.Because the discharge capacity of compressor increases, reach
To more excellent heat transfer effect.If the temperature value T2 for detecting hot water to be added is higher than T1, as shown in Fig. 2 control valve 50 is selected
Second flow path, the refrigerant that second flow path will open into the compression unit 20 with controlling organization 23 is directly communicated to the output of compressor
End, a rotor idle running for compression unit 20, the gas of compression refrigerant is not played a part of.Now only another compression unit 20
Work.Now compressor displacement is only a discharge capacity for compression unit 20, and whole mechanism heat reduces, and the corresponding heat exchanger of whole machine is changed
Hot area also can accordingly reduce, so as to realize individually heating the function of certain a part of hot water.
In the embodiment of Fig. 1 and Fig. 2, control method also includes：
If T2 is more than T1, a condenser 30 is controlled to be connected with compressor by the first control stream；
If T2 is less than or equal to T1, two condensers 30 are controlled to be connected with compressor by the first control stream.
When the temperature value T2 for detecting hot water to be added is less than T1, as shown in figure 1, two compression units 20 simultaneously participate in system
Heat, the discharge capacity increase of compressor, synchronously increase can then reach more excellent heat exchange effect to the supporting heat exchange power of condenser 30 of correspondence
Really.When the temperature value T2 for detecting hot water to be added is higher than T1, only one of which compression unit 20 participates in heating, and the discharge capacity of compressor subtracts
Small, whole mechanism heat reduces, and the corresponding heat exchange power of condenser 30 of whole machine also can accordingly reduce, so as to realize individually heating a certain
The function of part hot water.
In the embodiment of Fig. 1 and Fig. 2, control method also includes：
If T2 is more than T1, an evaporator 40 is controlled to be connected with compressor by the second control stream；
If T2 is less than or equal to T1, two evaporators 40 are controlled to be connected with compressor by the second control stream.
When the temperature value T2 for detecting hot water to be added is less than T1, as shown in figure 1, two compression units 20 simultaneously participate in system
Heat, the discharge capacity increase of compressor, synchronously increase can then reach more excellent heat exchange effect to the supporting heat exchange power of evaporator 40 of correspondence
Really.When the temperature value T2 for detecting hot water to be added is higher than T1, only one of which compression unit 20 participates in heating, and the discharge capacity of compressor subtracts
Small, whole mechanism heat reduces, and the corresponding heat exchange area of evaporator 40 of whole machine also can accordingly reduce, so as to realize individually heating a certain
The function of part hot water.
Technical scheme is directed to defect of the prior art, can improve whole mechanism heat in low water temperature section, reduce
The water heating time simultaneously lifts whole machine Energy Efficiency Ratio；Slow down whole function effect specific damping in water temperature high section.In low water temperature stage, whole machine system
System switching compressor is multi cylinder running status, and water heating is carried out with maximum capacity.And being stepped up with water temperature, water temperature
After uniform temperature is reached, by the mechanism of the cylinder-variable volume in compressor, switching compressor is that the mode of low discharge capacity is transported
OK.Whole water heating procedures system is set to maintain larger heating capacity and Energy Efficiency Ratio higher.
