Cold-producing medium compresses in compressor 6, enters indoor evaporative condenser 13 and condenses, it is achieved heat supply in winter function, subsequently into throttling
Valve 12 throttles, and enters back into generator 5 and completes evaporation.
As shown in Figure 4, when refrigeration system quits work, closing valve 4, this is to prevent issuable ammonia from entering
Compressor is circulated, it is ensured that solution composition.Now, refrigerant solution liquid-cooled transformer oil circuit, then completed by solution pump 15
Solution circulates, and utilizes the cooling water of absorber 14 to take away heat in refrigerant solution.The most both ensure that temperature of oil in transformer, to former
System is not the most changed, and system structure is simple, it is to avoid the cooling way adding other again brings the increase on cost.
In sum, the compression absorption composite refrigeration system of the present embodiment, simple in construction, easy to use, situation can be divided
The transformator waste heat in comprehensive utilization season in winter in summer two, and owing to two flow processs have shared part circuit and parts, decrease system
Complexity and cost.
