The specific embodiment
In order to make object, technical scheme and the advantage of patent of the present invention clearer, below in conjunction with drawings and the embodiments, patent of the present invention is further elaborated.Should be appreciated that the specific embodiment described herein, only in order to explain the content of patent of the present invention, is not intended to limit the present invention the content of patent.
As shown in Figure 1, the centralized local dehumidifing & Cooling apparatus of work plane is mainly comprised of dehumidifying and cooling device, heat pump assembly, solution regenerator and control system four parts.Dehumidifying and cooling device is positioned at the right-hand member of whole device, mainly by blower fan 1, dehumidifier homogenizing plate 9, drencher 10, dehumidifying liquid bath 12, is connected in turn; Heat pump assembly is positioned at the left side of dehumidifying and cooling device, by evaporimeter 8, compressor 15, condenser 6, choke valve 7, is formed by connecting in turn, and wherein the output of the cold junction of evaporimeter 8 is connected with the import of drencher 10 in dehumidifying and cooling device by pipeline; Solution restorer is positioned at the left side of heat pump assembly, by homogenizing plate 5, drencher 18, induced draft fan 4, regeneration liquid bath 19, heat exchanger 3 and catch basin 23, connected in turn, wherein drencher 23 entrances are connected with the hot junction output of condenser in heat pump assembly 6 by pipeline.Control system 25 is at the high order end of whole device, and it is the motor switch of controlling whole device, and the signal that can transmit controller gives a response and can timing operation and close whole device.The major control object of control system 25 has induced draft fan, fluid level controller, solution pump, electromagnetic valve and heat pump assembly.
Embodiment.
Press " ON " key of control panel to start control system 25, this system can be opened solution pump, heat pump assembly, induced draft fan successively.After startup system, dehumidification solution enters heat pump assembly by solution pump, after heat pump assembly is processed, flow to drencher, air intake flows into dehumidifying and cooling device under the effect of air inlet fan 1 simultaneously, return flows into solution regenerator under the effect of induced draft fan 4, and drencher sprays it respectively again.
In dehumidifying and cooling device, the solution that dehumidifying liquid bath is 12 li flows into the evaporimeter 8 of heat pump assembly by solution pump 13 parts, and another part is flowed in regeneration liquid bath 19 by liquid level equilibrium pipeline.This part the cold solution that flows into heat pump assembly evaporimeter 8 cold junctions sprays by 10 pairs of air of drencher, and at this moment air contacts with cold concentrated solution, and solution has been taken away airborne moisture, thereby air has become the air of low temperature drying, by air duct, discharges.Meanwhile, cold concentrated solution becomes weak solution that temperature is slightly high and flow in dehumidifying liquid bath 12 after spray.
In solution regenerator, the solution that regeneration liquid bath is 18 li flows into the condenser 6 of heat pump assembly by solution pump 17 parts, and another part flows in dehumidifying liquid bath 12 by liquid level equilibrium pipeline.This part solution that flows into heat pump assembly condenser 6 hot junctions has become hot weak solution and has sprayed by 18 pairs of return air air of drencher, at this moment air contacts with hot weak solution, air has been taken away the moisture in solution, thereby solution becomes cold concentrated solution, flow in regeneration liquid bath 19.Air has become the higher hot air of water capacity simultaneously, and by induced draft fan 4 pipeline inflow heat exchangers 3, air is in 3 li of condensations of heat exchanger, and condensed liquid flows to catch basin 23 by cover plate 22.
In heat pump, the output of the cold junction of evaporimeter 8 is connected with drencher 10 in dehumidifying and cooling device, and air intake air is sprayed; The hot junction output of condenser 6 is connected with drencher in solution regenerator 18, and return air air is sprayed; The solution inlet port of evaporimeter 8 and the solution inlet port of condenser 6 are connected with the output channel of dehumidifying liquid bath 12, regeneration liquid bath 19 respectively again simultaneously.
In control system, in the function key of control panel, there are " automatically " and " manually " two buttons.Select " automatically " to represent that apparatus of the present invention dehumidify according to the best effect on moisture extraction setting; Select after " manually ", can on oneself display screen on the right, set the time of dehumidifying.During the normal work of this device, " normally " indicator lamp lights, and when device breaks down, " fault " indicator lamp can light, and other lamp goes out.When the water in catch basin 23 is expired, " water is full " lamp lights, and the fluid level controller 21 in catch basin 23 passes the signal along to control system 25, and control system 25 regulates the water level in catch basin 23 by controlling electromagnetic valve 24.
Under normal circumstances, the liquid level difference between dehumidifying and cooling device and solution regenerator belongs to a dynamic balance.When the liquid level of dehumidifying in liquid bath 12 is higher, fluid level controller 11 wherein can pass the signal along to control system 25, control system 25, by controlling electromagnetic valve 14, is pumped into regeneration liquid bath 19 by the liquid level having more by liquid level equilibrium pipeline by solution pump 13, finally reaches liquid level equilibrium.When the liquid level of regeneration in liquid bath 19 is higher, contrary with upper a kind of situation, fluid level controller 20 in regeneration liquid bath 19 can pass the signal along to control system 25, and control system 25 is passed through electromagnetic valve 16, and by solution pump 17, the liquid level having more is pumped in dehumidifying liquid bath 12 by liquid level equilibrium pipeline.
