Description
Technical field
The utility model relates to heat exchange equipment or air conditioner technical fields, and in particular to a kind of air source heat pump frosting is dynamic
State monitors system.
Background technique
Air conditioner is a kind of common household electrical appliance.When air conditioner is when running heating mode in winter, because refrigerant is in outdoor
Evaporation endothermic in heat exchanger, to reduce the surface temperature of outdoor heat exchanger.If air conditioner is in the case where outdoor temperature is extremely low
Continuous service heating mode, then the surface condensation of outdoor heat exchanger is a large amount of white, to influence the normal work of air conditioner.
It is not absolutely required to carry out defrosting processing after heat exchanger surface frosting, only reach certain journey in influence heat exchange efficiency
It is just handled when spending.Currently, whether needing to carry out defrosting processing for the frosting of heat exchanger surface, judgment criteria is most
It is to be judged based on temperature, is to think frosting when temperature is lower than a certain temperature, needs to carry out defrosting processing.This side
Formula is easy to appear to be judged by accident because weather influences, and causes to carry out maloperation.
Utility model content
The purpose of this utility model the judgment method whether handled for current heat exchanger surface frosting not
Accurate problem provides a kind of air source heat pump frosting dynamic monitoring system.
In order to realize above-mentioned purpose of utility model, the utility model provides following technical scheme:
A kind of air source heat pump frosting dynamic monitoring system, including frosting detection part, temperature detection part, Humidity Detection

Humidity;The judgement part is default for judging whether the frosting thickness, the air themperature and the air humidity meet
Condition issues defrosting instruction if meeting;The preset condition is less than for the frosting thickness and is equal to preset thickness, and described
Air humidity is greater than or equal to default humidity, and the air themperature is less than or equal to preset temperature.
Preferably, the temperature detection part is arranged in outdoor unit air inlet position, the Humidity Detection component arrangement
In outdoor unit air inlet position.
Preferably, frosting detection part includes detection ring, detection ring inside is circumferentially disposed have it is multiple red
For detecting frosting thickness, the detection ring set is located on the heat exchanger tube of air source heat pump outer distance member.
Disclosed herein as well is a kind of air source heat pump frosting dynamic monitoring methods, and it is thick to obtain heat exchange pipe external surface frosting
The air themperature information of degree, the air humidity of heat exchanger tube local environment and heat exchanger tube local environment, if the frosting thickness, described
Air humidity and the air themperature reach preset condition and then defrost.
Preferably, the preset condition is that frosting thickness is greater than or equal to preset thickness.
Preferably, the preset condition is that the frosting thickness is less than and is equal to preset thickness, and the air humidity
More than or equal to default humidity, and the air themperature is less than or equal to preset temperature.
Preferably, the value range of the preset thickness be 3mm~5mm, the default humidity value range be 65%~
85%, the value range of the preset temperature is 0 DEG C~1 DEG C.
Preferably, the preset thickness is 4mm, the default humidity is 75%, and the preset temperature is 0.5 DEG C.
Compared with prior art, the utility model has the beneficial effects that using frosting thickness, air humidity and air themperature into
Whether the frosting of row comprehensive descision is handled, and is judged compared to only with temperature, application scheme is for frosting pair
The influence of heat exchange efficiency can more accurately judge, can more accurately judge whether to need to carry out defrosting processing;Pass through
Infrared distance measurement ring is set, is guaranteed for frost layer being monitored without dead angle on heat exchange pipeline section;Compared to only with frosting thickness into
Row judgement, the application be based on frosting thickness, in combination with temperature and humidity anticipation frosting thickness increase and decrease situation, so as to
Frosting thickness carries out defrosting operation before continuing growing, and frosting is avoided seriously to be difficult to remove, and the risk for white core occur is reduced, if meeting
There is the case where frosting thickness reduces then to be not necessarily to carry out defrosting processing, nature defrosting can be carried out at ambient conditions, to save
It saves the energy and reduces the case where accidentally defrosting, not only ensure that indoor level of comfort but also reduce the Unit Commitment as caused by defrosting,
The service life for increasing unit is finally reached the purpose for saving energy consumption.
Detailed description of the invention:
Fig. 1 is the preset condition of the application;
Fig. 2 is the preset condition of the application;
Fig. 3 is the programmed logic figure of judgement part;
Fig. 4 is the connection block diagram that the application monitors system.
