Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model adsorbent bed;

Fig. 3 is the generalized section of the utility model adsorbent bed.

The specific embodiment

In conjunction with Fig. 1,2 and Fig. 3, tell about the groundwork of absorption type air-conditioning below, people are called absorption with liquid to the absorption of gas, and solid is called absorption to the absorption of gas.Absorption type refrigerating is meant that the adsorption of the evaporant that utilizes solid adsorbent liquid towards adsorbate reduces system's dividing potential drop, thereby impels the continuous evaporation of liquid adsorbate to absorb heat to reach the purpose of refrigeration.What device adopted is active carbon---R134a working medium is right.Active carbon is as a kind of adsorbent, and it has stable performance, and is anticorrosive, has very strong adsorbability and adsorbance big to R134a, and desorb is easy, and characteristics such as reusable edible.Active carbon is very sensitive to temperature to the adsorbance of R134a simultaneously, small temperature traverse will cause that the adsorbance to R134a has bigger change, thereby cause the bigger variation of pressure in the bounded system, like this, utilize the temperature traverse of active carbon just can make it play the effect of compressor in the common air-conditioning.Device utilizes this principle, alternately takes off, inhales R134a by the active carbon in two adsorbent beds and reach continuous cooling.Take off the active carbon that heating agent (water or oil) heating that i.e. utilization heated by tail gas adsorbed R134a and make its desorption, the R134a steam in the condenser condenses heat release after enter evaporator again behind the liquid storage cylinder, expansion valve decrease temperature and pressure; Inhale promptly the intact R134a of desorption and come gaseous state R134a in the from evaporator drier, further evaporate heat absorption to impel the liquid R134a in the evaporator by the charcoal absorption behind the refrigerant cool drying.System leans on draught head and potential difference to realize the circulation of refrigerant, and heating agent and refrigerant then circulate by acting in the heat-transfer pipe of circulation pump, and in fact active carbon plays vacuum pump when cooling absorption, and plays compressor when heating desorption.

Working process of the present utility model is as follows:

Behind the starting of air conditioner, at first enter preceding half period, as Fig. 1, as establish adsorbent bed I4 heating desorption and adsorbent bed II20 cooling absorption, triple valve I6, heat exchanger 11 and triple valve II15 form the loop at this moment, and heating agent ceaselessly is heated by heat exchanger 11 under the effect of heat medium circulation pump 14, and adsorbent bed I4 again flows through, thereby heating adsorbent bed I4 promptly forms the heating agent loop.Opposite triple valve III16, cooling vessel 25 and triple valve IV18 form the loop, and refrigerant constantly cools off by cooling vessel 25 heat radiations under the effect of refrigerant circulation pump 21, the adsorbent bed II20 that flows through again, thus make adsorbent bed II20 cooling, and form the refrigerant loop.This moment, two-way valve II2 and III23 opened and two-way valve I3 and IV22 close, adsorbent bed I4 and condenser 19 are communicated with and adsorbent bed II20 and evaporator 5 connections like this, active carbon in the adsorbent bed II20 is in the unsaturation state for the absorption of R134a, thereby absorption comes the R134a gas of from evaporator drier 5 to impel the dividing potential drop in the evaporator 5 to reduce, and causes liquid R134a in the evaporator 5 constantly to evaporate heat absorption and freezes.And under the ringing of heating agent, the active carbon in the adsorbent bed I4 is constantly separated sucking-off R134a steam owing to be heated intensification, and the R134a steam to condenser 19, forms the R134a steam of high pressure-temperature through two-way valve II2 at this section.The R134a steam of High Temperature High Pressure is condensed into liquid refrigerant for the outside heat automatic release owing to temperature is higher than ambient temperature in condenser 19.The liquid state that returns to low pressure (low temperature) through throttling devices such as liquid storage cylinder 17 and expansion valves 7 flow in the evaporator 5 more then, and whole process forms the circulation as Fig. 2.

When adsorbent bed I4 no longer separates sucking-off R134a, then enter the back half period, heat exchanger 11, triple valve II (15), adsorbent bed II (20) and triple valve IV (18) form the heating agent loop at this moment, and cooling vessel 25, triple valve III (16), adsorbent bed I4 and triple valve I6 form the refrigerant loop.Open two-way valve I (3) and IV (22) simultaneously and close two-way valve II (2) and III (23), adsorbent bed II (20) and condenser 19 are communicated with and adsorbent bed I4 and evaporator 5 connections like this.Similar with the front, because the circulation heat-absorbing action of refrigerant, this moment, adsorbent bed I4 owing to lower the temperature made active carbon wherein be in the unsaturation state for the absorption of R134a, thereby absorption comes the R134a gas of from evaporator drier 5 to impel the dividing potential drop in the evaporator 5 to reduce, and causes liquid R134a in the evaporator 5 constantly to evaporate heat absorption and freezes.And under the ringing of heating agent, the active carbon in the adsorbent bed II20 is constantly separated sucking-off R134a steam owing to be heated intensification, and the R134a steam to condenser 19, forms the R134a steam of high pressure-temperature through two-way valve IV22 at this section.The R134a steam that is in High Temperature High Pressure in condenser 19 is condensed into liquid refrigerant for the outside heat automatic release owing to temperature is higher than ambient temperature.The liquid state that returns to low pressure (low temperature) through throttling devices such as liquid storage cylinder 17 and expansion valves 7 flow to evaporator 5 more then.

Simply, entire work process of the present utility model is exactly constantly alternately desorb and the absorption refrigeration agent of two adsorbents in the adsorbent bed, makes constantly evaporation and absorbing heat of liquid refrigerant in the evaporator, thereby reaches the purpose of continuous cooling.

A working cycle with adsorbent bed I is an example:

Process 1: heating agent is under heat medium circulation pump 14 effects, and circular flow is through adsorbent bed I4, and the active carbon in the adsorbent bed is heated and separates adsorption desorption R134a, and this moment, system's dividing potential drop and temperature all raise.

Process 2: the heating agent adsorbent bed I (4) that continues to flow through, the active carbon in the adsorbent bed continues to separate adsorption desorption R134a, and the R134a steam goes out condensation and heat release at condenser 19 under the cooresponding saturated pressure of ambient temperature, and promptly this moment, pressure was certain, and temperature build-up.

Process 3: refrigerant is under 21 effects of refrigerant circulation pump, and circular flow is through adsorbent bed I4, and adsorbent bed etc. hold cooling, make system's dividing potential drop and temperature all reduce.

Process 4: the R134a gas in the isobaric absorption of active carbon among the adsorbent bed I4 evaporator 5, and the liquid R134a evaporation of constantly absorbing heat, thus cause drop in temperature.
