The specific embodiment
Below, before embodiment is described, to for the preliminary matter that should be readily appreciated that embodiment is described.
Fig. 1 means the schematic diagram of an example of adsorption type heat pump.
The adsorption type heat pump 10 that Fig. 1 illustrates for example has evaporimeter 11, be disposed at the condenser 12 of top and absorber 13a, the 13b of configuration in parallel between evaporimeter 11 and condenser 12 of evaporimeter 11.Space in adsorption type heat pump 10 is for example depressurized to the 1/100 atmospheric degree in atmospheric pressure～1/10.
In evaporimeter 11, be provided with cooling water pipe 11a that Cooling Water passes through and for the chassis 11b of store refrigerant.Cold-producing medium can make water or ethanol etc., makes water as cold-producing medium here.
In absorber 13a, 13b, be respectively arranged with heat conduction pipe arrangement 14 and adsorbent (drier) 15.And absorber 13a and evaporimeter 11 link via valve 16a, absorber 13b and evaporimeter 11 link via valve 16b.Adsorbent 15 is such as using active carbon, silica gel or zeolite etc.
At condenser 12, dispose the cooling water pipe 12a that a plurality of plate-shaped fins are installed.Between condenser 12 and absorber 13a, dispose valve 17a, between condenser 12 and absorber 13b, dispose valve 17b.
Valve 16a, 16b, 17a, 17b are for example according to opening and closing from the signal of telecommunication of control part (not shown) output.And condenser 12 and evaporimeter 11 link by pipe arrangement 18.
Below, the action of above-mentioned adsorption type heat pump 10 is described.
Here, under original state, suppose that valve 16a between evaporimeter 11 and absorber 13a and the valve 17b between absorber 13b and condenser 12 are open mode.And, suppose that valve 16b between evaporimeter 11 and absorber 13b and the valve 17a between absorber 13a and condenser 12 are closed condition.In addition, to the cooling water pipe of condenser 12, supply with cooling water, to the heat conduction pipe arrangement 14 of absorber 13b, supply with the hot water the heat heating of being discharged from electronic equipment.
In absorber 13a, along with the moisture in adsorbent 15 absorption atmosphere, the pressure decreased in absorber 13a.Because the valve 16a between absorber 13a and evaporimeter 11 is open mode, so the pressure in evaporimeter 11 also reduces, and follows in this, is stored in the water evaporation of chassis 11b, and from cooling water pipe, 11a captures latent heat.Thus, the temperature of the water passing through in cooling water pipe 11a declines, and discharges the cooling water of low temperature from cooling water pipe 11a.In this cooling water such as the air-conditioning indoor, electronic equipment cooling etc., use.
The steam producing at evaporimeter 11 enters in absorber 13 via valve 16a, is adsorbed agent 15 absorption.
When absorber 13a a side implement to utilize adsorbent 15 adsorption moistures absorption process during, at the opposing party's absorber 13b, implement to make the step for regeneration of adsorbent 15 regeneration (being dried).That is, in absorber 13b, the moisture being adsorbed by adsorbent 15 is become steam by the hot water heating passing through in heat conduction pipe arrangement 14, and departs from from adsorbent 15.The steam producing at absorber 13b enters in condenser 12 by the valve 17b of open mode.
From absorber 13b, enter the steam of condenser 12 interior by the water quench of passing through in cooling water pipe 12a, in surrounding's condensation of cooling water pipe 12a and become liquid.This liquid moves to evaporimeter 11 via pipe arrangement 17, and is stored in the 11b of chassis.
If the adsorbent 15 in absorber 13a has adsorbed moisture to a certain degree, the adsorption efficiency of adsorbent 15 reduces.Therefore, control part is switching to absorber 13a by the supply destination of hot water from absorber 13b after the constant time, and makes valve 16a, 17b become closed condition, makes valve 16b, 17a become open mode.Thus, start to utilize adsorbent 15 adsorption moistures in absorber 13b, thus and adsorbent in absorber 13a 15 moisture evaporation adsorbents 15 regeneration.
By take like this constant time, the supply destination of hot water is switched between absorber 13a and absorber 13b as unit to adsorption type heat pump 10 continuous operations.
Yet, as mentioned above, need to supply with cooling water to the cooling water pipe 12a of condenser 12.Conventionally, the cooling water of supplying with to condenser 12 is used recirculated water, and with cooling device, carries out cooling so that the temperature of recirculated water does not rise.If the electric weight consuming in cooling device is a lot, by the saving effect of using adsorption type heat pump to obtain, reduce.Therefore, in cooling device, mostly use the cooling tower of the smaller sprinkling-water type of power consumption.
Courage and insight, for the cooling tower of sprinkling-water type is set, needs larger space, is difficult to above-mentioned adsorption type heat pump to use in small-scale facility.
In the following embodiments, even if the adsorption type heat pump system that also can use in the smaller facility of scale and the driving method of adsorption type heat pump are described.

In condenser 22, dispose the pressure sensor 22b that detects the pressure in condenser 22.From the signal of this pressure sensor 22b output, be also passed to control part 30.
As valve 26a, 26b, 27a, 27b, can use by control part 30 and control the magnetic valve opening and closing, but in the present embodiment, use the differential pressure driving formula valve automatically opening and closing according to draught head, can realize further power saving.
Air cooling device 29 has pipe arrangement 29b and the Air Blast fan 29c that a plurality of plate-shaped fins 29a are installed, and from Air Blast fan 29c, between plate-shaped fins 29a, sends into extraneous air, carries out cooling thus to the cooling water circulating in pipe arrangement 29b (cold-producing medium).The entrance of air cooling device 29 is connected with the outlet of the cooling water pipe 22a of condenser 22 via pipe arrangement 35a, and the outlet of air cooling device 29 is connected with the attraction side of cooling water circulating pump 31 via pipe arrangement 35b.And the discharge side of cooling water circulating pump 31 is connected with the entrance of the cooling water pipe 22a of condenser 22 via pipe arrangement 35c.
At pipe arrangement 35c, dispose the flow sensor 43 of the temperature sensor 42a of the temperature that detects the cooling water of supplying with towards the cooling water pipe 22a of condenser 22 and the flow of detection cooling water.And, at pipe arrangement 35a, dispose detection from the temperature sensor 42b of the temperature of the cooling water of condenser 22 discharges.From the signal of said temperature sensor 42a, 42b and flow sensor 43 outputs, be also passed to control part 30.
The signal controlling cooling water circulating pump 31 of control part 30 based on from pressure sensor 22b, 41a, 41b, temperature sensor 42a, 42b and flow sensor 43 outputs, adjusts to the flow of the cooling water of condenser 22 supplies.And control part 30, by the hot water the heat heating by from discharges such as electronic equipments, be take the constant time as unit is alternately to the heat conduction pipe arrangement 24 of absorber 23a and 24 supplies of the heat conduction pipe arrangement of absorber 23b.
Below, the driving method of the adsorption type heat pump in above-mentioned adsorption type heat pump system is described.
Here, under original state, the adsorbent 25 of supposing absorber 23a is dry state, and the adsorbent 25 of absorber 23b is for having adsorbed the state of moisture.And, suppose to supply with and be heated to the hot water of 60 ℃～90 ℃ by the heat of discharging from electronic equipment to the heat conduction pipe arrangement 24 of absorber 23b.
(step for regeneration)
Due to heat conduction pipe arrangement 24 supplying hot waters to absorber 23b, so moisture is from adsorbent 25 evaporations of absorber 23b, the pressure rise in absorber 23b.Therefore, valve 26b becomes closed condition, and valve 27b becomes open mode, and steam enters condenser 22 from absorber 23b.And it is higher than the pressure in absorber 23a that the pressure in condenser 22 becomes, valve 27a becomes closed condition.
Steam from absorber 23b enters condenser 22 is become liquid by the water quench of passing through in cooling water pipe 22a.This liquid moves to evaporimeter 21 by pipe arrangement 28, and is stored in chassis 21b.
By the heat conduction pipe arrangement 24 to absorber 23b at constant time remaining supplying hot water, 25 regeneration (being dried) of adsorbent in absorber 23b.
(absorption process)
In absorber 23a, adsorbent 25 adsorption moistures, thus, it is lower than the pressure in evaporimeter 21 that the pressure in absorber 23a becomes, and valve 26a becomes open mode.Thus, the pressure in evaporimeter 21 also reduces, and as the water evaporation of cold-producing medium, from cooling water pipe, 21a captures latent heat.As a result, the temperature of the water passing through in cooling water pipe 21a declines, and discharges the cooling water of low temperature from cooling water pipe 21a.In this cooling water such as the air-conditioning indoor, electronic equipment cooling etc., use.
Steam in evaporimeter 21 interior generations enters in absorber 23a via valve 26a, and is adsorbed agent 25 absorption.
In addition, adsorbent 25 produces heat when adsorption moisture.Therefore, being preferably circulation in the heat conduction pipe arrangement 24 of the absorber (absorber 23a or absorber 23b) in the process in implementing absorption process has cooling water, thus cooling adsorbent 25.In this case, the heat conduction pipe arrangement 24 of the absorber of the part that for example can make the cooling water of discharging from air cooling device 29 the process in implementing absorption process flows, or the air cooling device that absorber is used is set in addition.
(switching of step for regeneration and absorption process)
Adsorbent 25 in absorber 23a has adsorbed after moisture to a certain degree, and the adsorption efficiency of adsorbent 25 reduces.Therefore, control part 30 switches to absorber 23a by the supply destination of hot water from absorber 23b after the time through constant.Like this, in absorber 23a, be adsorbed the moisture evaporation of agent 25 absorption, thus the pressure rise in absorber 23a, valve 26a becomes closed condition, and valve 27a becomes open mode.Thus, the steam producing in absorber 23a enters in condenser 22.
On the other hand, in absorber 23b, stop the supply of hot water, the pressure in absorber 23b reduces.Thus, valve 27b becomes closed condition, and valve 26b becomes open mode, and the steam producing at evaporimeter 21 enters in absorber 23b.
Like this, take the constant time switches the supply destination of hot water as unit between absorber 23a and absorber 23b, thus, and adsorption heat pump 20 continuous operations.
(control of the cooling water of supplying with to condenser)
In condenser 22, condensate moisture and produce condensation heat, the temperature of the cooling water passing through in cooling water pipe 22 rises.In the present embodiment, utilize 29 pairs of these cooling waters of air cooling device to carry out cooling, and again to condenser 22, supply with.In this case, if the temperature of cooling water and the difference of outside air temperature of discharging from condenser 22 are little, the heat exchanger effectiveness step-down of air cooling device 29, wastes electric power in vain.Therefore, in the present embodiment, thereby cooling water circulating pump 31 is controlled to the flow of adjusting the cooling water of supplying with to condenser 22 so that the temperature of the cooling water of discharging from condenser 22 higher more than 2 ℃ than outside air temperature, be preferably high more than 5 ℃.
But, if improving the heat exchanger effectiveness of air cooling device 29, wish reduces terrifically the flow of the cooling water of supplying with to condenser 22, the amount of moisture in condenser 22 interior condensations reduces, and the internal face of the absorber (absorber 23a or absorber 23b) in the process of implementing step for regeneration produces dewfall.Moisture in the internal face dewfall of absorber is adsorbed agent 25 absorption from internal face evaporation in upper once absorption process.Therefore, although can not cause adsorption type heat pump 20 to stop action because of the dewfall of the internal face of absorber, but the evaporation of the moisture in absorber is unfavorable for the cooling of the cooling water that passes through in the cooling water pipe 21a of evaporimeter 21, therefore become the reason that the performance of adsorption type heat pump 20 reduces.
Therefore, in the present embodiment, utilize the pressure in the absorber (absorber 23a or absorber 23b) in pressure sensor 22b, 41a, the pressure in 41b instrumentation condenser 22 and the process in implementing step for regeneration being configured in condenser 22 and absorber 23a, 23b.And then, in the situation that the difference of the pressure in the absorber in the pressure in condenser 22 and the process in implementing step for regeneration departs from from the scope of regulation, the discharge rate of 30 pairs of cooling water circulating pumps 31 of control part is controlled, so that in the scope of the difference of the pressure in the absorber in the pressure in condenser 22 and the process in implementing step for regeneration in regulation.
The difference of the pressure in the absorber in the pressure in condenser 22 and process in implementing step for regeneration is little means that the amount of moisture of condensation in condenser 22 is few, easily in absorber, produces dewfall.Although preferably the difference of the pressure in condenser 22 and the pressure in the absorber in the process in implementing step for regeneration is large, but the difference of the pressure in the absorber in the pressure in condenser 22 and process in implementing step for regeneration is limited by outside air temperature, cannot be greatly to a certain extent more than.
In the present embodiment, thereby control cooling water circulating pump 31a and adjust quantity delivered from cooling water to condenser 22 that supply with, so that in the scope of the pressure differential of the absorber (absorber 23a or absorber 23b) in the process in implementing step for regeneration and condenser 22 at 1kPa～2kPa.
But, the absorber (absorber 23a or absorber 23b) in the process in implementing step for regeneration with the proper range of the pressure differential of condenser 22 according to the temperature of hot water to adsorption type heat pump 20 supplies, kind of adsorbent 25 etc. and different.Preferably wait and obtain the suitable pressure limit corresponding with each condition by experiment in advance, and be recorded in control part 30.
(effect)
As mentioned above, the related adsorption type heat pump system utilization of present embodiment has and 29 pairs of cooling waters of discharging from condenser 22 of the pipe arrangement 29b of fin 29a and the air cooling device of Air Blast fan 29c are installed carry out cooling.Therefore, do not need the large-scale equipment such as sprinkling-water type cooling tower, even if can use adsorption type heat pump in small-scale facility yet.
And, in the related adsorption type heat pump system of present embodiment, adjust the flow of the cooling water of supplying with to condenser 22, so that the difference of the pressure in the pressure in condenser 22 and absorber 23a, 23b is within the limits prescribed.Thus, the heat exchanger effectiveness of air cooling device 29 can be improved, further power saving can be realized.And, can prevent moisture (cold-producing medium) dewfall in absorber 23a, the 23b in the process in implementing step for regeneration, therefore can avoid the performance of adsorption type heat pump 20 to reduce.
(variation 1)
In the first above-mentioned embodiment, in air cooling device 29, from Air Blast fan 29c, to fin 29a, blow extraneous air and carry out cooling to cooling water.But, for example as shown in Fig. 3 (a), also can arrange and spray pipe arrangement 51a, to fin 29a, spray water.Therefore in this case, during aqueous vapor, from fin 29a, capture latent heat, compare with the situation that only blows extraneous air to fin 29a, the cooling capacity of air cooling device 29 improves.
And, as shown in Fig. 3 (b), can, from being disposed at the injection pipe arrangement 51b water spray between Air Blast fan and fin 29a, towards fin 29a, blow because of the air after the reduction of heat of gasification temperature.In this case, identical with the situation of Fig. 3 (a), to compare with the situation that only blows extraneous air to fin 29a, the cooling capacity of air cooling device 29 improves.
(variation 2)
In the first above-mentioned embodiment, according to having or not dewfall in the poor judgement absorber of the pressure in the absorber (absorber 23a or absorber 23b) in the pressure in condenser 22 and the process in implementing step for regeneration.But, for example, as illustrated for example in Fig. 4, also can in absorber 23a, 23b, configure humidity sensor 52a, 52b, control part 30 is determined with without dewfall according to the output of these humidity sensors 52a, 52b.

(variation 3)
If the heat that the condenser heat producing during water vapor condensation in condenser 22 absorbs from hot water than the absorber (absorber 23a or absorber 23b) in the process in implementing step for regeneration is few, condensation scarce capacity and produce dewfall in absorber.
In variation 3, as shown in Figure 6, temperature sensor 54a, the 54b of the temperature that detects the hot water of supplying with to absorber 23a, 23b are set, temperature sensor 55a, the 55b of the temperature of hot water that detection is discharged from absorber 23a, 23b.And, detection is set at flow sensor 56a, the 56b of the flow of the interior mobile hot water of heat conduction pipe arrangement 24 of absorber 23a, 23b.
Control part 30, according to the output of said temperature sensor 54a, 54b, 55a, 55b and flow sensor 56a, 56b, calculates the caloric receptivity of the absorber (absorber 23a or absorber 23b) in the process in implementing step for regeneration.And control part 30, according to the output of temperature sensor 42a, 42b and flow sensor 43, calculates the condenser heat of condenser 22.And then control part 30 is adjusted cooling water circulating pump 31 so that the caloric receptivity of absorber is identical with the condenser heat of condenser 22.Thus, can access the effect identical with above-mentioned embodiment.
