Detailed description of the invention
Below, before embodiment is described, should be readily appreciated that the preliminary matter of embodiment is described to being provided for.
Fig. 1 is the schematic diagram of the example representing adsorption type heat pump.
Fig. 1 the adsorption type heat pump 10 illustrated of illustrating there is evaporimeter 11, be configured at the condenser 12 of the top of evaporimeter 11 and absorber 13a, 13b configured in parallel between evaporimeter 11 with condenser 12.Space in adsorption type heat pump 10 is such as depressurized to the 1/100 atmospheric degree in atmospheric pressure ~ 1/10.
Cooling water pipe 11a that Cooling Water passes through and the chassis 11b for store refrigerant is provided with in evaporimeter 11.Cold-producing medium can use water or ethanol etc., uses water as cold-producing medium here.
Heat conduction pipe arrangement 14 and adsorbent (drier) 15 is respectively arranged with in absorber 13a, 13b.Further, absorber 13a and evaporimeter 11 link via valve 16a, and absorber 13b and evaporimeter 11 link via valve 16b.Adsorbent 15 such as uses active carbon, silica gel or zeolite etc.
The cooling water pipe 12a being provided with multiple plate-shaped fins is configured with at condenser 12.Between condenser 12 and absorber 13a, be configured with valve 17a, between condenser 12 and absorber 13b, be configured with valve 17b.
Valve 16a, 16b, 17a, 17b are such as according to the signal of telecommunication opening and closing exported from control part (not shown).Further, condenser 12 and evaporimeter 11 are linked by pipe arrangement 18.
Below, the action of above-mentioned adsorption type heat pump 10 is described.
Here, in an initial condition, suppose that the valve 16a between evaporimeter 11 and absorber 13a and the valve 17b between absorber 13b and condenser 12 is open mode.Further, suppose that the valve 16b between evaporimeter 11 and absorber 13b and the valve 17a between absorber 13a and condenser 12 is closed condition.In addition, to the cooling water pipe supply cooling water of condenser 12, the heat conduction pipe arrangement 14 to absorber 13b supplies the hot water after being heated by the heat of discharging from electronic equipment.
In absorber 13a, along with the moisture in adsorbent 15 adsorb atmospheric, the pressure in absorber 13a reduces.Because the valve 16a between absorber 13a and evaporimeter 11 is open mode, the pressure therefore in evaporimeter 11 also reduces, and is accompanied by this, and is stored in the water evaporation of chassis 11b, captures latent heat from cooling water pipe 11a.Thus, the temperature of the water passed through in cooling water pipe 11a declines, and discharges the cooling water of low temperature from cooling water pipe 11a.This cooling water such as uses in the air-conditioning of indoor, the cooling of electronic equipment etc.
The steam produced at evaporimeter 11 enters in absorber 13 via valve 16a, is adsorbed by adsorbent 15.
During the absorber 13a a side implements to utilize the absorption process of adsorbent 15 adsorption moisture, implement to make adsorbent 15 regenerate the step for regeneration of (drying) at the absorber 13b of the opposing party.That is, in absorber 13b, the moisture adsorbed by adsorbent 15 is become steam by the hot water heating that passes through in heat conduction pipe arrangement 14, and departs from from adsorbent 15.The steam produced at absorber 13b is entered in condenser 12 by the valve 17b of open mode.
The steam after in condenser 12 is entered by the water quench passed through in cooling water pipe 12a, condensation around cooling water pipe 12a and become liquid from absorber 13b.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, then the adsorption efficiency of adsorbent 15 has reduced.Therefore, the supply destination of hot water is being switched to absorber 13a from absorber 13b by control part after Time constant, and makes valve 16a, 17b become closed condition, makes valve 16b, 17a become open mode.Thus, start adsorbent 15 adsorption moisture utilized in absorber 13b, and in absorber 13a adsorbent 15 moisture evaporation thus adsorbent 15 regenerate.
By being switched between absorber 13a and absorber 13b the supply destination of hot water in units of the constant time like this, adsorption type heat pump 10 operates continuously.
But, as mentioned above, need the cooling water pipe 12a to condenser 12 to supply cooling water.Usually, the cooling water supplied to condenser 12 uses recirculated water, and carries out cooling to make the temperature of recirculated water not rise with cooling device.If the electricity consumed in cooling device is a lot, then the saving effect obtained by using adsorption type heat pump reduces.Therefore, the cooling tower of the sprinkling-water type mostly using power consumption smaller in cooling device.
Courage and insight, in order to arrange the cooling tower of sprinkling-water type, needs larger space, is difficult to above-mentioned adsorption type heat pump to use in small-scale facility.
In the following embodiments, even if be described the driving method of the adsorption type heat pump system that also can use in the facility that scale is smaller and adsorption type heat pump.

The magnetic valve being controlled opening and closing by control part 30 can be used as valve 26a, 26b, 27a, 27b, but in the present embodiment, use the differential pressure driving formula valve according to draught head automatically opening and closing, further power saving can be realized.
Air cooling device 29 has the pipe arrangement 29b and Air Blast fan 29c that are provided with multiple plate-shaped fins 29a, sends into extraneous air from Air Blast fan 29c between plate-shaped fins 29a, cools thus to the cooling water circulated 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.Further, 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.
The flow sensor 43 of the temperature sensor 42a of the temperature detecting cooling water supply towards the cooling water pipe 22a of condenser 22 and the flow of detection cooling water is configured with at pipe arrangement 35c.Further, the temperature sensor 42b of the temperature detecting the cooling water of discharging from condenser 22 is configured with at pipe arrangement 35a.The signal exported from said temperature sensor 42a, 42b and flow sensor 43 is also passed to control part 30.
Control part 30, based on the signal controlled cooling model water-circulating pump 31 exported from pressure sensor 22b, 41a, 41b, temperature sensor 42a, 42b and flow sensor 43, adjusts the flow of the cooling water supplied to condenser 22.Further, control part 30, by by the hot water after the heat heating of discharging from electronic equipment etc., supplies alternately to the heat conduction pipe arrangement 24 of absorber 23a and the heat conduction pipe arrangement 24 of absorber 23b in units of the constant time.
Below, the driving method of the adsorption type heat pump in above-mentioned adsorption type heat pump system is described.
Here, in an initial condition, suppose that the adsorbent 25 of absorber 23a is dry state, the state of adsorbent 25 for adsorbing moisture of absorber 23b.Further, suppose to supply to the heat conduction pipe arrangement 24 of absorber 23b the hot water being heated to 60 DEG C ~ 90 DEG C by the heat of discharging from electronic equipment.
(step for regeneration)
Due to heat conduction pipe arrangement 24 supplying hot water to absorber 23b, therefore moisture evaporates from the adsorbent 25 of absorber 23b, the pressure increase in absorber 23b.Therefore, valve 26b becomes closed condition, and valve 27b becomes open mode, and steam enters condenser 22 from absorber 23b.Further, the pressure in condenser 22 becomes higher than the pressure in absorber 23a, and valve 27a becomes closed condition.
Steam after entering condenser 22 from absorber 23b is become liquid by the water quench passed through in cooling water pipe 22a.This liquid is moved to evaporimeter 21 by pipe arrangement 28, and is stored in chassis 21b.
By the heat conduction pipe arrangement 24 to absorber 23b at Time constant sustainable supply hot water, the adsorbent 25 in absorber 23b regenerates (drying).
(absorption process)
In absorber 23a, adsorbent 25 adsorption moisture, thus, the pressure in absorber 23a becomes lower than the pressure in evaporimeter 21, and valve 26a becomes open mode.Thus, the pressure in evaporimeter 21 also reduces, and the water as cold-producing medium evaporates, and captures latent heat from cooling water pipe 21a.As a result, the temperature of the water passed through in cooling water pipe 21a declines, and discharges the cooling water of low temperature from cooling water pipe 21a.This cooling water such as uses in the air-conditioning of indoor, the cooling of electronic equipment etc.
The steam produced in evaporimeter 21 enters in absorber 23a via valve 26a, and is adsorbed by adsorbent 25.
In addition, adsorbent 25 produces heat when adsorption moisture.Therefore, being preferably circulation in the heat conduction pipe arrangement 24 being in the absorber (absorber 23a or absorber 23b) in the process implementing absorption process has cooling water, thus cooling adsorbent 25.In this case, the heat conduction pipe arrangement 24 that a part for the cooling water of discharging from air cooling device 29 is being in the absorber the process implementing absorption process such as can be made to flow, or the air cooling device of absorber is set in addition.
(switching of step for regeneration and absorption process)
After adsorbent 25 in absorber 23a has adsorbed moisture to a certain degree, the adsorption efficiency of adsorbent 25 reduces.Therefore, the supply destination of hot water is being switched to absorber 23a from absorber 23b by control part 30 after the constant time.Like this, evaporated in absorber 23a by the moisture that adsorbent 25 adsorbs, the pressure increase therefore in absorber 23a, valve 26a becomes closed condition, and valve 27a becomes open mode.Thus, the steam produced 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 produced at evaporimeter 21 enters in absorber 23b.
Like this, switched the supply destination of hot water in units of the constant time between absorber 23a and absorber 23b, thus, adsorption heat pump 20 operates continuously.
(control to the cooling water of condenser supply)
In condenser 22, condensate moisture and produce condensation heat, the temperature of the cooling water passed through in cooling water pipe 22 rises.In the present embodiment, utilize air cooling device 29 to cool this cooling water, and again supply to condenser 22.In this case, if the difference of the temperature of cooling water of discharging from condenser 22 and outside air temperature is little, then the heat exchanger effectiveness step-down of air cooling device 29, wastes power in vain.Therefore, in the present embodiment, cooling water circulating pump 31 is controlled thus adjusts the flow of cooling water supplied to condenser 22, to make the temperature of the cooling water of discharging from condenser 22 higher than outside air temperature more than 2 DEG C, preferably high more than 5 DEG C.
But, if reduce the flow of the cooling water supplied to condenser 22 terrifically for the heat exchanger effectiveness improving air cooling device 29, then the amount of moisture of condensation in condenser 22 reduces, and the internal face of the absorber (absorber 23a or absorber 23b) in the process implementing step for regeneration produces condensation.The moisture condensed at the internal face of absorber is adsorbed from internal face evaporation by adsorbent 25 in upper once absorption process.Therefore, although adsorption type heat pump 20 will be caused to stop action because of the condensation of the internal face of absorber, but the evaporation of the moisture in absorber is unfavorable for the cooling of the cooling water passed through in the cooling water pipe 21a of evaporimeter 21, therefore the reason that the performance becoming adsorption type heat pump 20 reduces.
Therefore, in the present embodiment, utilize pressure sensor 22b, 41a, the 41b be configured in condenser 22 and absorber 23a, 23b to measure the pressure in condenser 22 and be in the pressure in the absorber (absorber 23a or absorber 23b) in the process of enforcement step for regeneration.And then, pressure in condenser 22 departs from from the scope specified with the difference of the pressure in the absorber be in the process implementing step for regeneration, the discharge rate of control part 30 pairs of cooling water circulating pumps 31 controls, and is in the scope of regulation with the difference of the pressure in the absorber be in the process implementing step for regeneration to make the pressure in condenser 22.
With the difference of the pressure in the absorber be in the process implementing step for regeneration is little, pressure in condenser 22 means that the amount of moisture of condensation in condenser 22 is few, easily in absorber, produce condensation.Although the pressure preferably in condenser 22 is large with the difference of the pressure in the absorber be in the process implementing step for regeneration, but the pressure in condenser 22 limits by outside air temperature with the difference of the pressure in the absorber being in the process implementing step for regeneration, cannot greatly to a certain extent more than.
In the present embodiment, controlled cooling model water-circulating pump 31a thus adjustment to supply the quantity delivered of cooling water to condenser 22, to make to be in the pressure differential of the absorber (absorber 23a or absorber 23b) in the process implementing step for regeneration and condenser 22 in the scope of 1kPa ~ 2kPa.
But the absorber (absorber 23a or absorber 23b) be in the process implementing step for regeneration is different according to the temperature of the hot water supplied to adsorption type heat pump 20, the kind of adsorbent 25 etc. from the proper range of the pressure differential of condenser 22.Preferably by experiment etc. obtain the suitable pressure limit corresponding with each condition in advance, and be recorded in control part 30.
(effect)

Further, in the adsorption type heat pump system involved by present embodiment, the flow of the cooling water supplied to condenser 22 is adjusted, to make the difference of the pressure in condenser 22 and the pressure in absorber 23a, 23b within the limits prescribed.Thereby, it is possible to improve the heat exchanger effectiveness of air cooling device 29, further power saving can be realized.Further, can prevent being in moisture (cold-producing medium) condensation in absorber 23a, 23b in the process implementing step for regeneration, therefore, it is possible to avoid the performance of adsorption type heat pump 20 to reduce.
(variation 1)

(variation 3)
If the condenser heat produced during water vapor condensation in condenser 22 is fewer than the heat that absorbs from hot water of absorber (absorber 23a or absorber 23b) be in the process implementing step for regeneration, then condensing capacity is not enough and produce in absorber and condense.
