Abstract
The utility model discloses a kind of air-cooled medical cupboard, comprise the cabinet with Condensing units; Condensing units comprises refrigeration compressor, exports with refrigeration compressor the condenser be connected, and condensator outlet is connected with the evaporimeter be arranged in cabinet refrigerating chamber by expansion valve, and evaporator outlet is connected with refrigeration compressor import; The circulating fan controlled by temperature and humidity controller is provided with in refrigerating chamber; The pipeline being communicated in condenser and expansion valve or capillary is provided with the refrigeration magnetic valve controlled by temperature and humidity controller, and refrigeration compressor outlet is connected with described evaporator with pipeline by the hot gas defrosting magnetic valve controlled by temperature and humidity controller; Hot gas defrosting magnetic valve interlocks with refrigeration magnetic valve and arranges.The utility model advantage is to reach the effect of little, the without exception sound of temperature rise amplitude in medical cupboard, thus realizes energy-saving and cost-reducing object.
Description
Technical field
The utility model relates to medical cupboard, especially relates to air-cooled medical cupboard.
Background technology
At present, domestic air-cooled medical cupboard in humidification more adopts electrical heating defrosting, namely make evaporimeter defrosting by the air of the electric heater for heating evaporimeter periphery being arranged on medical cupboard base of evaporator, the condensation globule or frost layer that condense in evaporator surface are heated as wet-hot steam and carry out humidification.Because electric heating tube is in evaporimeter external heat, heat can not be used for warming and humidifying completely, make partial heat by the direct forced convertion of evaporation fan (wind circulating fan) in medical cupboard, and the efficiency of heating surface of electric heating tube itself is not high, and (electric heating tube is direct resistance heated, the efficiency of heating surface is about 80%), causing condensing in the condensation globule of evaporator surface or frost layer, to be heated as the wet-hot steam time longer, medicine in-cabinet temperature ascensional range is large, and also can cause abnormal voice when there being lower of the globule to encounter high-temperature electric heating tube.
Summary of the invention
The utility model object is to provide a kind of air-cooled medical cupboard.
For achieving the above object, the utility model takes following technical proposals:
Air-cooled medical cupboard described in the utility model, comprises the cabinet with Condensing units; Described Condensing units comprises refrigeration compressor, exports with described refrigeration compressor the condenser be connected, described condensator outlet is connected with the evaporimeter be arranged in described cabinet refrigerating chamber by expansion valve or capillary, and described evaporator outlet is connected with refrigeration compressor import; The circulating fan controlled by temperature and humidity controller is provided with in described refrigerating chamber; The pipeline being communicated in described condenser and expansion valve or capillary is provided with the refrigeration magnetic valve controlled by described temperature and humidity controller, and described refrigeration compressor outlet is connected with described evaporator with pipeline by the hot gas defrosting magnetic valve controlled by temperature and humidity controller; Described hot gas defrosting magnetic valve interlocks with refrigeration magnetic valve and arranges.
The utility model advantage is when needing humidification defrosting in described refrigerating chamber, control to open described hot gas defrosting magnetic valve by described temperature and humidity controller and close refrigeration magnetic valve, now, the direct bypass of high-temperature high-pressure refrigerant steam that refrigeration compressor is discharged is to evaporator, high-temperature high-pressure refrigerant steam carries out exchange heat from the copper pipe inside of evaporimeter to outside and carries out defrosting, defrosting efficiency is up to 100%, defrost time is short, reach the effect of little, the without exception sound of temperature rise amplitude in medical cupboard, thus realize energy-saving and cost-reducing object.
Accompanying drawing explanation
Fig. 1 is the structural representation of air-cooled medical cupboard described in the utility model.
Fig. 2 is the refrigeration system schematic diagram of Condensing units described in utility model.
Detailed description of the invention
As shown in Figure 1, 2, air-cooled medical cupboard described in the utility model, comprises the Condensing units 2 be arranged on bottom cabinet 1 in operating room; Described Condensing units 2 comprises refrigeration compressor 3, exports with described refrigeration compressor 3 condenser 4 be connected, described condenser 4 is exported and is connected with the evaporimeter 7 be arranged in described cabinet refrigerating chamber 6 by expansion valve 5 or capillary, and described evaporimeter 7 outlet is connected with refrigeration compressor 3 import; The circulating fan 8 controlled by temperature and humidity controller is provided with in described refrigerating chamber 6; The pipeline being communicated in described condenser 4 and expansion valve 5 or capillary is provided with the refrigeration magnetic valve 9 controlled by described temperature and humidity controller, and the outlet of refrigeration compressor 3 is connected with the import of described evaporimeter 7 with pipeline by the hot gas defrosting magnetic valve 10 controlled by temperature and humidity controller; Described hot gas defrosting magnetic valve 10 interlocks with refrigeration magnetic valve 9 and arranges.
Utility model works principle is summarized as follows:
When refrigerating chamber 6 humidity is lower in limited time lower than setting, temperature and humidity controller sends instruction, carry out humidification, that is: Condensing units 2, hot gas defrosting magnetic valve 10 and circulating fan 8 is opened, because refrigeration magnetic valve 9 and hot gas defrosting magnetic valve 10 are interlocked relationship, the magnetic valve 9 that therefore freezes cuts out simultaneously, the high-temperature high-pressure refrigerant steam that now refrigeration compressor 3 is discharged enters in evaporimeter 7 by hot gas defrosting magnetic valve 10 and pipeline, heat exchange is carried out by the condensation globule on the copper pipe wall of evaporimeter 7 and evaporimeter 7 copper pipe outer wall or frost layer, the condensation globule or frost layer is made to become damp-heat air, by circulating fan 8 at refrigerating chamber 6 Inner eycle humidification, through damp and hot exchange, medical cupboard inner circulating air humidity strengthens gradually, until medical cupboard humidity reaches setting value, temperature and humidity controller sends instruction, closes compression condensation unit 2, hot gas defrosting magnetic valve 10, circulating fan 8, humidification terminates.
