BACKGROUND OF THE PRESENT INVENTION 
     1. Field of Invention 
     This invention belongs to the area of low-temperature residual heat utilization using the heat pump technology. 
     2. Description of Related Arts 
     Under the premise that heat pump can promote the residual heat temperature to the needed level of user, it is an effective way to develop residual heat by adopting heat pump technology which can bring a better energy conservation, environmental protection and economic interest. In the place of rich waste heat resources, the heating temperature of the second-type low temperature absorption heat pump can&#39;t meet the needs of customers if the residual heat temperature is relatively low or the hot demand temperature of users is relatively high. Now, we need adopt the second-type high temperature absorption heat pump which can achieve a higher temperature. 
     The driving force of the second-type absorption heat pump is the temperature difference between waste heat resources and environment. The temperature difference is relatively small. So in the second-type absorption heat pump, it is the first principle to get the second-type high temperature absorption heat pump with reasonable process and simple structure. Too much heat transfer links may not only lead to that the structure and process of heat pump unit is complex, but also have a great impact on the enhancement effect of residual heat temperature in heat pump units. So reducing the heat transfer links in the improving process of the residual heat temperature not only is beneficial to a further promoting of the residual heat temperature, but also is good for a further simplify of heat pump structure. 
     On the premise of greatly enhancing of waste heat temperature, simplify the structure and reducing heat transfer links, the invention comes up with a method to improve the heating temperature of the second-type absorption heat pump. Based on the existing heat pump units, the heating temperature of which is relatively low, we can get a series of second-type high temperature absorption heat pump by using this method. 
     SUMMARY OF THE PRESENT INVENTION 
     The main purpose of the invention is to provide a method which can improve the heating temperature of heat pump at first. Then, we use the method on the existing second-type absorption heat pump which only has a relatively low heating temperature. In this way, we can gain the corresponding second-type high temperature absorption heat pump. The specific contents of invention are as follows.

We adopt the solution tandem cycle as following. We change that generator or the steam bleeding chamber has the concentrated solution pipe which passes through solution pump, solution heat exchanger and absorber to that generator or the steam bleeding chamber has the concentrated solution pipe which passes through solution pump, solution heat exchanger, absorber and the new added steam bleeding chamber. The new added steam bleeding chamber has the concentrated solution pipe which passes through the new added solution pump and the new added solution heat exchanger and then connects the new added absorber.

A part of the heating load heats up the solution which flows through absorber and then the solution enters the new added steam bleeding chamber releasing refrigerant vapor which is provided to condenser. At the same time, the concentrated solution is provided to the new added absorber. The other part of the heating load heats up the liquid refrigerant which flows through absorber and releases the high temperature refrigerant vapor which is provided to the new added absorber.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Now combining the appended drawings and examples, we described the invention in detail. 
     The two-stage high temperature second-type absorption heat pump shown in  FIG. 1 , based on the single stage second-type absorption heat pump, can be realized by the following way: 
     Firstly, structurally, we add the new added steam bleeding chamber  1 , the new added absorber  2 , the new added throttle  6 , the new added solution pump  3 , the new added solution heat exchanger  5  on the single stage second-type absorption heat pump which comprises generator, condenser, evaporator, absorber, solution pump, liquid refrigerant pump and solution heat exchanger. In the single stage second-type absorption heat pump, generator A 1  has the concentrated solution pipe which passes through solution pump E 1  and solution heat exchanger G 1  and then connects absorber D 1 . Absorber D 1  has the dilute solution pipe which passes through solution heat exchanger G 1  and then connects generator A 1 . Generator A 1  has the refrigerant vapor channel connected condenser B 1 . Condenser B 1  has the liquid refrigerant pipe which passes through liquid refrigerant pump F 1  and then connects evaporator C 1 . Evaporator C 1  has the refrigerant vapor channel connected absorber D 1 . Generator A 1  and evaporator C 1  have the residual heat medium pipe connected external. Condenser B 1  has the cooling medium pipe connected external. Absorber D 1  has the heated medium pipe connected external. 
     We adopt the solution tandem cycle as follows. We change that generator A 1  has the concentrated solution pipe which passes through solution pump E 1  and solution heat exchanger G 1  and then connects absorber D 1  to that generator A 1  has the concentrated solution pipe which passes through solution pump E 1 , solution heat exchanger G 1 , absorber D 1  and then connects the new added steam bleeding chamber  1 . The new added steam bleeding chamber  1  has the concentrated solution pipe that passes through the new added solution pump  3 , the new added solution heat exchanger  5  and then connects the new added absorber  2 . The new added absorber  2  has the dilute solution pipe which passes through the new added solution heat exchanger  5  and then connects absorber D 1 . We change that absorber D 1  have the residual heat medium pipe connected external to that absorber D 1  has the refrigerant vapor pipe connected the new added absorber  2  after that condenser B 1  has the liquid refrigerant pipe which passes through liquid refrigerant pump F 1  and then connects absorber D 1 . We change that condenser B 1  has the liquid refrigerant pipe which passes through liquid refrigerant pump F 1  and then connects evaporator C 1  to that condenser B 1  has the liquid refrigerant pipe which passes through liquid refrigerant pump F 1 , the new added throttle  6  and then connects evaporator C 1 . The new added steam bleeding chamber  1  has the refrigerant vapor channel connected condenser B 1 . The new added absorber  2  have the residual heat medium pipe connected external. 
     Secondly, on the process, absorber D 1  has the dilute solution which passes through solution heat exchanger G 1  and then enters generator A 1 . Then the solution is heated by the residual heat medium which flows through generator A 1  and releases refrigerant vapor provided to condenser B 1 . Generator A 1  has the concentrated solution which flows through solution pump E 1 , solution heat exchanger G 1  and enters absorber D 1  where it absorbs heat and part of it is vaporization. Then it enters the new added steam bleeding chamber  1 . The new added steam bleeding chamber  1  releases refrigerant vapor which is provided to condenser B 1  while the concentrated solution flows through the new added solution pump  3 , the new added solution heat exchanger  5  and then connects the new added absorber  2 . Then the concentrated solution absorbs the refrigerant vapor came from absorber D 1  and the provided the high temperature heating load to the heated medium. The new added absorber  2  has the dilute solution which flows through the new added solution heat exchanger  5  and then enters absorber D 1  where it absorbs the refrigerant vapor came from evaporator C 1  and releases heat. 
     The refrigerant vapor, which enters condenser B 1  from generator A 1  and the new added steam bleeding chamber  1 , releases heat to the cooling medium and becomes liquid refrigerant. The liquid refrigerant flows through liquid refrigerant pump F 1  and then is divided into two parts. One part of the liquid refrigerant flows through the new added throttle  6  and then enters evaporator C 1  where it absorbs residual heat and becomes refrigerant vapor provided to absorber D 1 . In absorber D 1 , the refrigerant vapor is absorbed by the solution and releases heat to the other road of solution and liquid refrigerant which flows through absorber D 1 . The other part flows through absorber D 1  and absorbs heat becoming refrigerant vapor which is provided to the new added absorber  2 . At first, the concentration of the solution which enters the new added absorber  2  is promoted by the generator A 1  for the first time. And then, the solution concentration is improved by the absorber D 1  and the new added steam bleeding chamber  1  for the second time. The refrigerant vapor which enters the new added absorber  2  is produced by the heating of absorber D 1 . The heating temperature of the new added absorber  2  is higher than the one of absorber D 1 . Consequently, we achieve the two stages improving of residual heat temperature. And we get the two-stage high temperature second-type absorption heat pump based on the single stage second-type absorption heat pump. 
     The two-stage high temperature second-type absorption heat pump shown in  FIG. 2 , based on the single stage second-type absorption heat pump, can be realized by the following way: 
     Firstly, structurally, we add the new added steam bleeding chamber  1 , the new added absorber  2 , the new added liquid refrigerant pump  4 , the new added solution pump  3 , the new added solution heat exchanger  5  on the single stage second-type absorption heat pump which comprises generator, condenser, evaporator, absorber, solution pump, liquid refrigerant pump and solution heat exchanger. In the single stage second-type absorption heat pump, generator A 1  has the concentrated solution pipe which passes through solution pump E 1  and solution heat exchanger G 1  and then connects absorber D 1 . Absorber D 1  has the dilute solution pipe which passes through solution heat exchanger G 1  and then connects generator A 1 . Generator A 1  has the refrigerant vapor channel connected condenser B 1 . Condenser B 1  has the liquid refrigerant pipe which passes through liquid refrigerant pump F 1  and then connects evaporator C 1 . Evaporator C 1  has the refrigerant vapor channel connected absorber D 1 . Generator A 1  and evaporator C 1  have the residual heat medium pipe connected external. Condenser B 1  has the cooling medium pipe connected external. Absorber D 1  has the heated medium pipe connected external. 
     We adopt the solution independent cycle as follows. The new added steam bleeding chamber  1  has the concentrated solution pipe that passes through the new added solution pump  3 , the new added solution heat exchanger  5  and then connects the new added absorber  2 . The new added absorber  2  has the dilute solution pipe which passes through the new added solution heat exchanger  5 , absorber D 1  and then connects the new added steam bleeding chamber  1 . We change that absorber D 1  have the residual heat medium pipe connected external to that absorber D 1  has the refrigerant vapor pipe connected the new added absorber  2  after that evaporator C 1  adds the liquid refrigerant pipe which passes through the new added liquid refrigerant pump  4  and then connects absorber D 1 . The new added steam bleeding chamber  1  has the refrigerant vapor channel connected condenser B 1 . The new added absorber  2  have the residual heat medium pipe connected external. 
     Secondly, on the process, the process to form the high temperature heating-side is as following. In the single second-type absorption heat pump which comprises generator, condenser, evaporator, absorber, liquid refrigerant pump and solution heat exchanger, the heating load is formed in absorber D 1  and can be divided into two parts. One part of the heating load heats up the solution which flows through the new added solution heat exchanger  5 , absorber D 1  form the new added absorber  2 . The solution is vaporization and then enters the new added steam bleeding chamber  1 . The other part heats up the liquid refrigerant which flows through the new added liquid refrigerant pump  4 , absorber D 1  form evaporator C 1 . And the liquid refrigerant becomes refrigerant vapor provided to the new added absorber  2 . 
     After that the vapor phase and liquid phase of the solution which enters the new added steam bleeding chamber  1  is separated, the refrigerant vapor enters condenser B 1  while the concentrated solution flows through the new added solution pump  3 , the new added solution heat exchanger  5  and then connects the new added absorber  2 . Then the concentrated solution in absorber  2  absorbs the refrigerant vapor came from absorber D 1  and provides the high temperature heating load to the heated medium. The refrigerant vapor, which enters condenser B 1  from the new added steam bleeding chamber  1 , releases heat to the cooling medium and becomes liquid refrigerant. 
     After that the liquid refrigerant flows through liquid refrigerant pump F 1 , the new added liquid refrigerant pump  4  and absorber D 1  where it absorbs heat and becomes refrigerant vapor with high temperature entered the new added absorber  2 . The solution concentration which enters the new added absorber  2  from the new added steam bleeding chamber  1  is higher than the one which enters absorber D 1  from generator A 1 . The temperature of refrigerant vapor which enters the new added absorber  2  from absorber D 1  is higher than the one which enters absorber D 1  from evaporator C 1 . Consequently, the exothermic temperature of the new added absorber  2  is much higher than the one of absorber D 1 .

One part of the heating load heats up the solution which flows through the second solution pump J 1 , absorber D 1  form the steam bleeding chamber I 1 . The solution is vaporization and then enters the new added steam bleeding chamber  1 . The other part heats up the liquid refrigerant which flows through liquid refrigerant pump F 1 , absorber D 1  form condenser B 1 .

Then the concentrated solution in absorber  2  absorbs the refrigerant vapor came from absorber D 1  and provides the high temperature heating load to the heated medium. The refrigerant vapor, which enters condenser B 1  from the new added steam bleeding chamber  1 , releases heat to the cooling medium and becomes liquid refrigerant.
