Abstract
The utility model relates to an indoor heat exchanger for an air conditioner. The utility model is a three-section type heat exchanger. A pair of steady state electromagnetic valves is connected in series between adjacent two sections of the heat exchanger above the heat exchanger, and another lower section of the heat exchanger. Both ends of the valve are communicated and connected in parallel with dehumidifying capillaries with proper length. The indoor heat exchanger for an air conditioner is applied to the indoor machine of the air conditioner. The utility model has the advantages that when dehumidification is required in winter, the dehumidification can be implemented without temperature decrease; that a room temperature is suitable for requirements and indoor humidity can be maintained within a certain range can be ensured; a technical effect of health dehumidification can be realized.
Description
The utility model relates to the improvement of air conditioner room unit, specifically is a kind of air-conditioner indoor heat exchanger, and it belongs to the air-conditioner technical field.
Existing conventional air conditioner is in service in the winter time, often meets the bigger situation of chamber indoor humidity.Under this situation, the dehumidification mode of conventional air conditioner generally adopts refrigeration mode, promptly when whole refrigeration system is in refrigerating operaton, make the evaporimeter low temperature dehumidification of indoor set, must cause that like this indoor temperature reduces, effect on moisture extraction is bad, can not reach the effect of room air fresh and comfortable.Traditional air-conditioning refrigeration system can not be lowered the temperature and remove temperature when heating operation.Existing refrigeration system and dehumidification mode can't solve " not cool-down dehumidification " this difficult problem.
The purpose of this utility model will solve air-conditioner exactly when heating, and does not lower the temperature and removes the difficult problem of temperature operation, and a kind of air-conditioner indoor heat exchanger is provided.This heat exchanger will improve structure configuration and compound mode.This heat exchanger is used for air-conditioner refrigerating system, can make indoor set when the dehumidifying operation, can realize dehumidification function, can guarantee that again the wind that air outlet of indoor set blows out is hot blast, satisfies people's needs.
Task of the present utility model is finished by following technical scheme, developed a kind of air-conditioner indoor heat exchanger, it is the syllogic heat exchanger, it is characterized in that: be connected in series a bistable state magnetic valve between two neighboring sections heat exchanger and the following other one section heat exchanger at this above the heat exchanger, and at these valve two ends the dehumidifying capillary that suitable length is arranged of connecting in parallel.
Described dehumidifying capillary, its caliber is: Φ 1.5-6.0mm, its suitable length are 40-200mm.
Described bistable electromagnetic valve, its model is: DFS3-20-DFS8-80RF.
Two neighboring sections heat exchanger above described, its every section heat exchanger are that parallel connection turns in the pipeline between system and the bistable electromagnetic valve, also can be that series connection turns in the pipeline between system and the bistable electromagnetic valve.
Other one section heat exchanger below described, its all tubulation are that branchs three tunnel parallel connections turn in the pipeline between bistable electromagnetic valve and the system, also can be to connect to turn in the pipeline between bistable electromagnetic valve and the system.
Advantage of the present utility model and good effect are: owing to adopt the syllogic heat exchanger, use bistable electromagnetic valve and the capillary control cryogen flow in parallel with it to and throttling, make refrigerant in three sections piece heat exchangers of syllogic heat exchanger, the not same-action of in different operational modes, bringing into play.When general normal air-conditioner refrigeration or heating operation, the bistable electromagnetic valve of configuration is unimpeded, and this syllogic heat exchanger role is constant, keeps the function of former refrigeration or heating operation.When needs heat dehumidifying, the top two neighboring sections heat exchanger of the syllogic heat exchanger of indoor set, because of the compressor of off-premises station just turns round with low frequency, make the high-pressure liquid refrigerant that flows to two sections heat exchangers above this have higher temperature, the heat release condensation in two sections heat exchangers on this of refrigerant this moment.This moment, bistable electromagnetic valve was closed obstructedly, and the refrigerant that flows through two sections heat exchangers above this can only throttling in the dehumidifying capillary in parallel with this magnetic valve, and continues to become low pressure liquid.The refrigerant of this low-pressure liquid enters in following other one section heat exchanger, just in time heat absorption evaporation, and airborne like this water vapour (moisture just) cold condensate on this section heat exchanger, and flow on the drip tray.Below this in one section heat exchanger with refrigeration mode running refrigerant, thereby reach the purpose of dehumidifying.This syllogic heat exchanger utilizes the local refrigerated dehumidification of segmentation, and the segmentation part heats air-supply, has realized the not effect of cool-down dehumidification, thereby guarantees the dry hot blast that is that air outlet of indoor set sends, with the demand of the fresh and comfortable that satisfies people.
Embodiment of the present utility model further specifies as follows in conjunction with the accompanying drawings:
Fig. 1 is air-conditioner indoor heat exchanger side-looking structure and system pipeline annexation figure.
Referring to Fig. 1, the direction of arrow among the figure is the flow direction of refrigerant in heating circulation.The indoor heat exchanger of making is applied in KFR-40GW/ (DBPJ) indoor machine of air-conditioner.This heat exchanger is the syllogic heat exchanger.Be connected in series a bistable state magnetic valve 4 between two neighboring sections heat exchanger 1,2 and the following other one section heat exchanger 3 at this above the heat exchanger, and in parallelly at these valve 4 two ends connect that length is arranged is the dehumidifying capillary 5 of 80mm.The caliber of this capillary 5 is Φ 2.5mm.The model of the bistable electromagnetic valve of selecting for use 4 is DFS3-20.The top two neighboring sections heat exchanger the 1, the 2nd of this heat exchanger, parallel connection turn in the pipeline between system pipeline 6 and the bistable electromagnetic valve 4.Should below one section other heat exchanger 3 be that the road parallel connection of branch three-way connection (pipe) turns in the pipeline between bistable electromagnetic valve 4 and the system pipeline 7.
