The specific embodiment
Below in conjunction with description of drawings basic structure of the present utility model and operation principle:
Existing smallpox built-in air-conditioning system profile as shown in Figure 1, it mainly comprises: return air grid 100, air outlet 101, panel 102, shell 103.Its refrigeration system principle is seen Fig. 2, mainly comprises: feed tube 4, expansion valve 11, blower fan 13, blower motor 12, evaporimeter 1, tracheae 15.During the work of air-conditioning unit, under blower fan 13 effects, room air flows through evaporimeter 1 with direction 3 and carries out heat exchange, and air is lowered the temperature and finished the part dehumidifying, and the cold-producing medium in the evaporimeter is discharged from tracheae 14 after absorbing airborne heat.The evaporimeter of existing smallpox built-in air-conditioning system is commonly used circular and square two kinds of forms, sees Fig. 3 and Fig. 4 respectively; The A of these two kinds of form evaporimeters sees Fig. 5 to amplification.
Structure of the present utility model comprises as shown in Figure 6: heat exchanger 15, motor 12, blower fan 13, magnetic valve 7, flow control valve 9, expansion valve 11.Arrow among the figure is represented the flow of refrigerant direction.Heat exchanger 15 is divided into evaporimeter 1 and reheater 2 two parts, and room air flows through evaporimeter 1 earlier along the direction shown in 3, again by reheater 2, realizes heat dehumidifying again.Liquid pipe 4 is divided into arm 5 and 6 two branch roads of arm, and the cold-producing medium that wherein flows through arm 5 enters reheater 2 after by flow control valve 9, realizes the cold excessively of cold-producing medium, and cold excessively cold-producing medium enters pipe 8 by tube connector 10; The cold-producing medium that wherein flows through arm 6 merges in the pipeline 8 by the liquid back pipe 10 of magnetic valve 7 backs with reheater 2, and the sub-cooled liquid refrigerant after converging enters evaporimeter 1 by expansion valve 11, and blower fan 13 adopts centrifugal blower.
At first the cold-producing medium of big supercooling degree carries out heat exchange at evaporimeter 1 position to room air with having very under the effect of blower fan 13, reduces temperature, separates out a large amount of condensed waters simultaneously, becomes supercooled air.Supercooled air flows to reheater 2, carries out heat exchange with cold-producing medium, and the temperature of cold-producing medium reduces, and the temperature of air raises, and has reduced relative humidity in the time of atmosphere temperature rising.By heat exchanger 15 being divided into evaporimeter 1 and reheater 2, the smallpox embedded air-conditioner has been realized hot dehumidification function again.By the different open degree of control flow control valve 9 and the switch of magnetic valve 7, can control flow, the different moisture removal of control room air, the comfort temperature of assurance room air by the cold-producing medium of reheater, comfortable living environment is provided, solves in heat and the dehumidifying problem in the wet environment.
The high-power dehumidification process of smallpox embedded air-conditioner is achieved as follows: close magnetic valve 7, flow control valve 9 is reached maximum, the liquid refrigerant of liquid pipe 4 all enters reheater 2 by arm 5 and flow control valve 9, and enter expansion valve 11 by tube connector 10,8 and carry out throttling, gas-liquid mixture after the throttling enters evaporimeter 1 and carries out heat exchange with room air, and cynical dose of the gaseous state system after the heat absorption is got back to compressor by tracheae 14.Expansion valve 11 can adopt capillary, thermal expansion valve, electric expansion valve etc.Carry out heat exchange in reheater inner refrigerant and the Cryogenic air of coming, realized further cold excessively by evaporimeter; Cold-producing medium is passed to Cryogenic air to heat simultaneously, the temperature of air is raise, and reduce the humidity of air.In reheater, be discharged from outdoor heat originally and be used effectively, eliminated the sub-cooled of air, realized heat dehumidifying again.There is cynical dose of the system of big supercooling degree to enter the surface temperature that evaporimeter 1 can reduce evaporimeter 1 very much by expansion valve 11, and the surface temperature that makes evaporimeter 1 is significantly less than the dew point of air, realize low temperature dehumidification, can remove airborne moisture significantly, realized high-power dehumidifying.
By opening magnetic valve 7, regulate flow control valve 9, can regulate entering reheater 24, all enter evaporimeter 1, realize the common refrigerating function of smallpox embedded air-conditioner.At this moment, not influence of 2 pairs of refrigerating functions of reheater.
Fig. 7 is the example that the utility model smallpox embedded air-conditioner evaporimeter 1 and reheater 2 are arranged, wherein 1A, 2B are evaporimeter, and 2 is reheater.The enlarged drawing of A direction is seen Fig. 8, and the enlarged drawing of A direction also can be selected Fig. 9 or Figure 10, and wherein the height of reheater is identical with the height of evaporimeter among Fig. 8, and the height of reheater is respectively 3/4 and 1/2 of evaporimeter height among Fig. 9, Figure 10.Along the flow direction 3 of air, air carries out heat exchange with evaporimeter 1 earlier, realizes cooling and dehumidifying significantly, and cold air and reheater 2 carry out heat exchange then, and air themperature raises, and reduces the humidity of air, realizes heat dehumidifying again.Enter the flow of the cold-producing medium of reheater 2 by adjusting, can regulate moisture removal, can realize high-power dehumidifying, can realize common air conditioning function.
Figure 11 is another example that smallpox embedded air-conditioner evaporimeter and reheater are arranged, wherein 1A, 1B are evaporimeter, and 2 is reheater, and the enlarged drawing of A direction can select that Fig. 8's-10 is any.Its operation principle is identical with Fig. 7, no longer narration.
