Description
Technical field
The invention belongs to HVAC technical field in new energy field, particularly to the defrosting of a kind of air-cooled heat pump unit
Control system.
Background technology
Current wide use air-cooled heat pump unit is at hot-summer and cold-winter area, the sky of hot summer and warm winter region refrigeration and heating
Adjusting system, mainly includes condenser, vaporizer, compressor, the big parts of choke valve four, at present in hot-summer and cold-winter area application process
In, the defrost mode of these air-cooled heat pump units has two classes: the first kind only simply controls the time, defrost completely by time control,
Once, unit reverse circulation 10 minutes, regardless of outdoor temperature height in defrost in the most every 30 minutes.Its energy expenditure is well imagined.
It was commonly used before unit uses Electronic Control.Equations of The Second Kind controls the time according to air themperature, when evaporator coil
When leaving air temp is less than a setting value, generally this temperature is 0～3 DEG C, starts timing, after 30 minutes, if temperature is also
It is less than setting value, then starts defrost.
Above-mentioned Defrost mode all exists or defrosting effect is undesirable, or operating cost is high, and system effectiveness is low waits deficiency.
Summary of the invention
The present invention is the weak point overcoming prior art, designs a kind of air-cooled heat pump unit with defrosting control,
The present invention can reach the effect of intelligent defrosting, and can reduce operating cost, improves system effectiveness.
A kind of air-cooled heat pump unit with defrosting control that the present invention proposes, it is characterised in that this system includes: air-cooled
Source pump, end side water circulating pump, butterfly valve, meteorologic parameter harvester, control chamber；Its annexation is: Air-Cooled Heat Pump Unit
The hot water outlet of condenser be connected with the water supply line butterfly valve of end heating, the hot water inlet of Air-Cooled Heat Pump Unit condenser with
End side recirculated water delivery side of pump is connected, and end side water circulating pump entrance is connected with the water return pipeline butterfly valve of end heating；Air-cooled
Source pump side walls installs meteorologic parameter harvester, and the communication link interface of meteorologic parameter harvester is connected with control chamber, air-cooled
The touch screen of source pump is connected with control chamber circuit.
The feature of the present invention and beneficial effect:
The present invention, in existing air-cooled heat pump unit, adds meteorologic parameter harvester and control chamber.The present invention is permissible
Reach the effect of intelligent defrosting, reduce operating cost, improve system effectiveness.
Accompanying drawing explanation
Fig. 1 is the system composition schematic diagram of the present invention.
Detailed description of the invention
This kind of defrosting control system with the air-cooled heat pump unit that defrosting controls proposed, in conjunction with accompanying drawing and enforcement
Example describes in detail as follows:
A kind of air-cooled heat pump unit with defrosting control that the present invention proposes forms as it is shown in figure 1, this system is mainly wrapped
Include: Air-Cooled Heat Pump Unit 1, end side water circulating pump 2, butterfly valve 32, butterfly valve 33, meteorologic parameter harvester 4, control chamber 5；It connects
Relation is: the hot water outlet 11 of the condenser of Air-Cooled Heat Pump Unit 1 is connected with the water supply line butterfly valve 32 of end heating, air-cooled heat
The hot water inlet 12 of pump assembly 1 condenser is connected with the outlet of end side water circulating pump 2, end side water circulating pump 2 entrance and end
The water return pipeline butterfly valve 31 of end heating is connected；Air-Cooled Heat Pump Unit 1 side walls installs meteorologic parameter harvester 4, and meteorologic parameter is adopted
The communication link interface of storage 4 is connected with control chamber 5, and the touch screen of Air-Cooled Heat Pump Unit 1 is connected with control chamber 5 circuit.
Each parts detailed description of the invention of native system and function declaration are as follows:
Air-Cooled Heat Pump Unit 1, end side water circulating pump 2, butterfly valve 32, butterfly valve 33 all use conventional products, the most all with existing
Air-cooled heat pump unit component devices and function identical.
Meteorologic parameter harvester 4: use conventional temperature transmitter and relative humidity transmitter.
Performance is as follows:
Control chamber 5: use conventional PC computer, and be previously stored with collection determining program (for conventional programming techniques), electricity
Brain is arranged in a casing.
The operation principle of present system is described as follows
First native system stores the point of multiple arrival vapor pressure values reference value in computer program, respectively B1 point, B2 point,
B3 point, and set source pump and reach to carry out corresponding defrosting time during each steam pressure point reference value.
After native system heats beginning or defrosting, through several minutes stable operation, the computer record current weather ring in control chamber
Temperature that under border, meteorological parameter acquisition unit gathers and relative humidity data, find vapour pressure force reference value B by psychrometric chart.
Outdoor temperature is the lowest, and relative humidity is the biggest, the easiest frosting.If weather environment is bad, (snow sky, temperature are low
In-7 DEG C, relative humidity more than 60%), reaching to fall during vapour pressure reference value B at B1 point, computer controls source pump and carries out once
Defrosting 10min；If weather environment preferably (cloudy day, temperature between-7～0 DEG C, relative humidity 50%～more than 60%), reach
Falling at B2 point during vapour pressure reference value B, computer controls unit and once defrosts 8min；When weather environment is preferable (cloudy, warm
Degree is between 0～7 DEG C, within relative humidity 50%), reach to fall during vapour pressure reference value B at B3 point, computer controls unit and carries out one
Secondary defrosting 5min；(fine day, temperature are higher than 7 DEG C, within relative humidity 50%), Air-Cooled Heat Pump Unit table when weather environment is fine
Face frost-free, evaporating pressure keeps constant, and Air-Cooled Heat Pump Unit keeps heating operation not defrost.
Air-Cooled Heat Pump Unit typically makes system be transformed into refrigeration mode, High Temperature High Pressure from heating mode by cross valve commutation
Steam enters finned heat exchanger, makes outdoor finned heat exchanger function become condenser from vaporizer, thus by outdoor fin
Frost on formula heat exchanger is removed.
