Description
Technical field
The utility model belongs to technical field of central air, is specifically related to a kind of automatic defrosting type air energy thermal pump assembly.
Background technology
Known, after compressor operating a period of time of central air-conditioning, its evaporator fin surface meeting frosting, if do not carried out defrost, frost can be tied thicker and thicker, and air channel completely can be blocked by evaporator fin knot, cause cold wind not circulate, refrigeration declines.Current primary solutions is mounting temperature sensor on Central air-conditioning unit, contrasted by the evaporating temperature detecting outdoor environment temperature and outdoor heat exchanger and send the instruction whether defrosted to unit computer controller, although this kind of way defrosting effect is good, but there is certain drawback in actual use, 1. energy consumption is high, when outdoor environment humidity is low do not need defrosting time, unit also can judge defrost according to outdoor temperature, there is not guilty power consumption; 2., owing to defrosting termly according to set program, make heating water temperature fluctuated, heating water temperature is non-constant; 3., due to the defrosting that the plenty of time is unnecessary, make Energy Efficiency Ratio low; 4. unit operation is unstable, and when outdoor environment relative humidity height, defrosting is not thorough, and easily breaks down.
Utility model content
For prior art Problems existing, the purpose of this utility model is to provide a kind of automatic defrosting type air energy thermal pump assembly, passes through technological improvement, good defrosting effect can be reached, and effectively can control defrost function and automatically carry out, when not needing defrosting, can not work, avoid energy consumption to produce.
The utility model solves the technical scheme that its technical problem adopts: a kind of automatic defrosting type air energy thermal pump assembly, it comprises an air energy unit, generating set main body structure is identical with existing common machine set constructor, the tube connector comprising condenser and be connected with exterior line, described condenser fin is fixed with fin temperature sensor, the side of condenser is fixed with outdoor environment Temperature Humidity Sensor, it is compressor part bottom described condenser, near compressor part is electrical control cubicles, and electrical control cubicles is fixed with controller.
Described controller calculates dew-point temperature automatically by detecting warm and humid sensor, temperature on described dew-point temperature and fin temperature sensor is carried out real-time comparison and is obtained the temperature difference that defrosts, when the temperature that defrosts is greater than dew-point temperature, controller controls compressor bank and carries out defrosting work.
Be set with 4 grades of defrosting temperature difference and 5 grades of defrost interval in described controller, compared with the close two grades temperature approach that defrost by dew point temperature value and select to perform certain defrost interval.
The beneficial effects of the utility model: the utility model passes through Improvement, this automatic defrosting type air energy thermal pump assembly adds fin temperature sensor and outdoor environment Temperature Humidity Sensor, under the control of the controller, described controller calculates outdoor environment dew-point temperature automatically by sensing chamber's external environment Temperature Humidity Sensor, temperature on described dew-point temperature and fin temperature sensor is carried out real-time comparison and is obtained the temperature difference that defrosts, when the temperature difference that defrosts is greater than dew-point temperature, controller controls compressor bank and carries out defrosting work, simultaneously, set 4 grades of defrosting temperature difference and 5 grades of defrost interval, to be compared with the close two grades temperature approach that defrost by dew point temperature value and select to perform certain defrost interval, the more original simple measurement outdoor temperature of the utility model and heat exchange temperature more accurate than right Defrost mode, controller controls compressor part only does suitable duration defrosting campaign when frosting, energy consumption reduces, and water temperature is constant, defrosting thoroughly.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is conducted further description.
A kind of automatic defrosting type air energy thermal pump assembly, it comprises an air energy unit 1, generating set main body structure is identical with existing common machine set constructor, the tube connector 3 comprising condenser 2 and be connected with exterior line, the fin of described condenser 2 being fixed with fin temperature sensor 21, the side of condenser 2 being fixed with the warm and humid sensor 22 of outdoor environment, is compressor part 4 bottom described condenser 2, near compressor part 4 is electrical control cubicles 5, electrical control cubicles 5 is fixed with controller 6.
During utility model works, its operation principle is that controller 6 calculates dew-point temperature automatically by the humiture on the warm and humid sensor 22 of sensing chamber's external environment, temperature on described dew-point temperature and fin temperature sensor 21 is carried out real-time comparison and is obtained the temperature difference that defrosts, when the temperature that defrosts is greater than dew-point temperature, controller 6 controls compressor part 4 and carries out defrosting work, simultaneously, the utility model sets 4 grades of defrosting temperature difference and 5 grades of defrost interval in controller 6, to be compared select to perform certain defrost interval by dew point temperature value with the close two grades temperature approach that defrost.When ambient temperature and humidity measures exception or fault, controller is certainly decided to be defrost interval 5 minutes or other periods carry out interval defrosting.When the utility model normally works, defrost interval is run according to controlling compressor part 4 interval time of default, and the defrosting temperature difference is larger, and the frost layer represented on fin is thicker, and defrosting time is longer.
