Description

Latent heat sensible heat is separated the Household air conditioner refrigeration system controlled
Technical field
The present invention relates to a kind of latent heat sensible heat and be separated the Household air conditioner refrigeration system controlled.
Background technology
The humiture of domestic air-conditioning system all adopts unified control mostly at present, and there are the following problems thus:
(1) there is energy waste in the wet Combined Treatment of heat.Indoor remaining wet owing to adopting dehumidification by condensation method to get rid of, evaporator surface temperature needs the dew-point temperature lower than room air, considering heat transfer temperature difference and the medium transport temperature difference, as realized the dew-point temperature of 16.6oC, needing the evaporating temperature of about below 7oC.Therefore often in order to reach the object of dehumidifying, reduce evaporating temperature, and concerning compressor, pressure ratio increases, entering power increases, and runs uneconomical as far as possible.
(2) change adapting to heat moisture ratio is difficult to.Usual indoor heat moisture ratio changes in the larger context, and by reducing evaporating temperature, realize reducing indoor humidity, air-conditioning system response is comparatively slow, and meanwhile, the indoor temperature after cooling is often lower, and indoor comfort is poor.
Simultaneously commercial rotary wheel dehumidifying mode air conditioning systems is not suitable as domestic air-conditioning system, the independent temperature-humidity control of rotary wheel dehumidifying mode air conditioning systems, adopt rotary wheel dehumidifying pattern, it is because of the factor such as equipment and cost, and commercial air conditioning system is applied to domestic air-conditioning system not economically feasible.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of latent heat sensible heat and is separated the Household air conditioner refrigeration system controlled, this air-conditioning refrigeration system overcomes the defect of conventional domestic air-conditioning system, native system device simple, without the need to increasing special dehumidification equipment, reach the object of dehumidifying, cooling, effective reduction system cloud gray model energy consumption, improves indoor comfort and air quality.
For solving the problems of the technologies described above, latent heat sensible heat of the present invention is separated the air-conditioning refrigeration system controlled and comprises duplex cylinder compressor, first reservoir, second reservoir, first evaporimeter, second evaporimeter, first electric expansion valve, second electric expansion valve, condenser, indoor fan and outdoor fan, described duplex cylinder compressor is respectively equipped with exhaust outlet and two air entries, two air entries of described duplex cylinder compressor are connected with the second reservoir with described first reservoir respectively, described first reservoir is connected one end of described first evaporimeter and the second evaporimeter respectively with the suction end of the second reservoir, described first evaporimeter is connected described condenser one end respectively by described first electric expansion valve with the second electric expansion valve with the other end of the second evaporimeter, the described condenser other end connects the exhaust outlet of described duplex cylinder compressor, described indoor fan is located at the phase nearside of described first evaporimeter and the second evaporimeter, described outdoor fan is located at described condenser side.
Technique scheme is have employed because latent heat sensible heat of the present invention is separated the Household air conditioner refrigeration system controlled, namely this air-conditioning refrigeration system comprises duplex cylinder compressor, first reservoir, second reservoir, first evaporimeter, second evaporimeter, first electric expansion valve, second electric expansion valve, condenser chamber inner blower and outdoor fan, duplex cylinder compressor is respectively equipped with exhaust outlet and two air entries, two air entries of duplex cylinder compressor respectively with the first reservoir, second reservoir is connected, first reservoir, the suction end of the second reservoir connects one end of the first evaporimeter and the second evaporimeter respectively, first evaporimeter is connected condenser one end respectively by the first electric expansion valve with the second electric expansion valve with the other end of the second evaporimeter, the condenser other end connects the exhaust outlet of duplex cylinder compressor, indoor fan is located at the phase nearside of the first evaporimeter and the second evaporimeter, outdoor fan is located at condenser side.This air-conditioning refrigeration system overcomes the defect of conventional domestic air-conditioning system, native system device simple, without the need to increasing special dehumidification equipment, reaching the object of dehumidifying, cooling, effectively reducing system cloud gray model energy consumption, improving indoor comfort and air quality.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is that latent heat sensible heat of the present invention is separated the Household air conditioner refrigeration system structural representation controlled.
Detailed description of the invention
As shown in Figure 1, latent heat sensible heat of the present invention is separated the air-conditioning refrigeration system controlled and comprises duplex cylinder compressor 1, first reservoir 9, second reservoir 10, first evaporimeter 2, second evaporimeter 3, first electric expansion valve 4, second electric expansion valve 5, condenser 6, indoor fan 7 and outdoor fan 8, described duplex cylinder compressor 1 is respectively equipped with exhaust outlet and two air entries, two air entries of described duplex cylinder compressor 1 are connected with the second reservoir 10 with described first reservoir 9 respectively, described first reservoir 9 and the suction end of the second reservoir 10 are connected one end of described first evaporimeter 2 and the second evaporimeter 3 respectively, described first evaporimeter 2 is connected described condenser 6 one end respectively by described first electric expansion valve 4 with the second electric expansion valve 5 with the other end of the second evaporimeter 3, described condenser 6 other end connects the exhaust outlet of described duplex cylinder compressor 1, described indoor fan 7 is located at the phase nearside of described first evaporimeter 2 and the second evaporimeter 3, described outdoor fan 8 is located at described condenser 6 side.
Native system is applied to Household air conditioner refrigeration system, its device simple, without the need to configuring special dehumidification equipment, as Revolving wheel dehumidification apparatus etc., by means of only adjustment evaporating temperature, change control strategy, just can reach dehumidifying object, namely by adjustment two evaporator temperatures be arranged in parallel, the object of dehumidifying, cooling is reached.In native system, compressor adopts duplex cylinder compressor, two suction ends corresponding cooling functions of difference of two reservoir configuration and two evaporimeters of dehumidification function, realize different pressures of inspiration(Pi), the exhaust of duplex cylinder compressor is unified to be come in compressor housing, connecting condenser through compressor exhaust outlet, carrying out condensation of refrigerant by crossing outdoor fan; The evaporating temperature of two evaporimeters can be set to 18 DEG C and 8 DEG C respectively, and corresponding respective electric expansion valve carries out the adjustment of refrigerant flow, realizes the function of cooling and dehumidifying respectively, and realizes heat exchange and air circulation by indoor fan.The air-conditioning refrigeration system of this form is easier to be realized in domestic air-conditioning system, reaches air-conditioning system latent heat sensible heat and is separated the object controlled, reduce system cloud gray model energy consumption, improve indoor comfort and air quality.
