Detailed Description
The invention is further described with reference to the following figures and examples.
The utility model discloses a multi-functional temperature regulation dehumidification unit of intelligence proportional control type improves original temperature regulation dehumidification unit, and the structure of unit is as shown in figure 1 before improving, including compressor 1, vapour and liquid separator 2, outdoor heat exchanger 5, indoor heat exchanger 6 and two 8 of indoor heat exchanger, wherein compressor 1 gas vent passes through the pipeline and connects in parallel outdoor heat exchanger 5 and indoor heat exchanger 6 respectively, later establishes ties expansion valve 7 in proper order, two 8 of outdoor heat exchanger, vapour and liquid separator 2 and the formation circulation circuit of compressor 1 induction port. Two ends of a branch of the outdoor heat exchanger 5 are respectively connected with the first electromagnetic valve 9 and the second check valve 12 in series, and two ends of a branch of the indoor heat exchanger 6 are respectively connected with the second electromagnetic valve 10 and the first check valve 11 in series. The unit controls temperature regulation and dehumidification through a first electromagnetic valve 9 and a second electromagnetic valve 10, when the indoor air outlet temperature is higher than a set temperature, the second electromagnetic valve 10 is closed, the first electromagnetic valve 9 is opened, at the moment, the air outlet temperature is rapidly reduced, when the indoor air outlet temperature is lower than the set temperature, the first electromagnetic valve 9 is closed, the second electromagnetic valve 10 is opened, and the temperature is increased again; in this process, the following problems occur: 1) the electromagnetic valve is frequently switched, so that the electromagnetic valve is finally damaged, and the service life is shortened; 2) in the switching process, because the air directly exchanges heat with the refrigerant in a direct expansion mode, the influence of each switching on the ambient temperature of the use side is great, the fluctuation of the outlet air temperature is great, and the stability is not realized.
The utility model discloses a multifunctional temperature-adjusting dehumidifying unit with proportion adjustment, the structure of which is shown in figure 2, comprising a compressor 1, wherein the exhaust port of the compressor 1 is communicated with the left port of a four-way valve 3, and the right port of the four-way valve 3 is connected with a gas-liquid separator 2 and a compressor 1 air inlet in sequence to form a loop; the upper port of the four-way valve 3 is connected with one end of an electric proportional control valve 4, the other two ends of the electric proportional control valve 4 are respectively connected with an outdoor heat exchanger 5 and a first 6 branch of an indoor heat exchanger in parallel, then an expansion valve 7, a second 8 branch of the indoor heat exchanger and a lower port of the four-way valve 3 are sequentially connected, and a gas-liquid separator 2 and a gas suction port of a compressor 1 are sequentially connected through a right port of the four-way valve 3. The five solenoid valves 15 are connected in series in the branch 5 of the outdoor heat exchanger, and the three check valves 18 are connected in series in the branch 6 of the indoor heat exchanger. A first bypass is connected between the outdoor heat exchanger 5 and the fifth solenoid valve 15 and between the right end port of the four-way valve 3 and the gas-liquid separator 2, wherein the first bypass is a pipeline formed by connecting a first capillary tube 16 and a third solenoid valve 3 in series; and a second bypass is connected between the first indoor heat exchanger 6 and the third check valve 18 and between the right end port of the four-way valve 3 and the gas-liquid separator 2, wherein the second bypass is a pipeline formed by connecting the second capillary tube 17 and the fourth electromagnetic valve 14 in series.
In the operation process of an original unit, due to the fact that the electromagnetic valve is continuously started and stopped, when the electromagnetic valve is in a closed state, the original unit is influenced by overhigh pressure of an outlet of the heat exchanger, a large amount of refrigerants are stored in the heat exchanger after the electromagnetic valve is powered off, the refrigerants do not participate in the circulation, the refrigerants are unbalanced due to continuous switching, a bypass device is additionally arranged by the aid of the capillary tube I16, the electromagnetic valve III 13, the capillary tube II 17 and the electromagnetic valve IV 14, when the electric proportional control valve is in an opening degree of 100% or 0%, the refrigerant circulation can be balanced by opening the electromagnetic valve in the bypass device, and the unit.
The reason that the condensing positions of the indoor heat exchanger I6 and the outdoor heat exchanger 5 of the original unit are provided with the check valves causes that if the unit adopts the four-way valve for defrosting, the refrigerant can not reversely flow, now the check valve II 12 in the original unit is replaced by the electromagnetic valve fifth 15, the electromagnetic valve fifth 15 is opened under the defrosting condition of the unit, and the unit can normally run under the defrosting condition.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
