Embodiment
The present invention is described further with specific embodiment below in conjunction with the accompanying drawings.
It is as shown in Figure 1 present system schematic diagram.
Gas-burning machine heat pump machine is Winter-summer dual purpose, cold (heat) water of heat pump main frame for water return pipeline be really share in the summer in winter it is a set of
Pipeline.And engine flue gas waste heat recoverer 4 can only produce hot water in season in summer in winter two, therefore this programme is by the cold of heat pump main frame
(heat) water is divided into two-way system for the confession water return pipeline of water return pipeline and engine flue gas waste heat recoverer 4, and the two is not mixed,
Engine flue gas waste heat recoverer 4 is only used for supplying heat supply in winter.Summer gas engine, which produces high-temperature flue gas, will pass through fume afterheat type
Lithium bromide chiller 8 produces air-conditioning or technique cold water.
In view of summer air-conditioning system based on cooling, heat is relatively rich more, therefore the combustion gas hair of gas-burning machine heat pump
Motivation cooling heat whole year does not reclaim, and its cooling water pipe of engine road is incorporated to the cooling water system of gas-burning machine heat pump condenser.Summer
Cooling Waste Heat of Engine drains into outside atmosphere environment with cooling tower 16 during season kind of refrigeration cycle, then as outdoor when winter heating is circulated
The auxiliary thermal source that heat pump heats when environment temperature is too low.
Because cooling tower 16 is open water system, algae and germ contamination, therefore gas engine cooling water are easily caused
System does not mix with the closed Water System of user.Pass through the enclosed water storage tank 5 with coil heat exchanger 6 and electric T-shaped valve 15
Synergy improve unit in the winter time worst cold case when cooling water supply temperature, both ensured the stabilization and water of user's supply water temperature
The water quality of system, ensure Effec-tive Function of the unit in the winter time under worst cold case using the fume afterheat of gas engine again.
The present invention is in summer operation：
1) chilled water supply air conditioner user (pipeline and auxiliary device configuration produced by the cooling in summer of gas-burning machine heat pump unit 1
It is identical with current central air-conditioning handpiece Water Chilling Units water system principle).
2) electric T-shaped valve 15 bypasses normally closed (with the enclosed water storage tank 5 with coil heat exchanger 6 without heat exchange), and combustion gas is started
Machine cooling water and main frame cooling water are in the presence of circulating pump to roof cooling tower 16 to outside atmosphere function of environment heat emission.
3) engine high-temperature fume afterheat driving fume afterheat type BrLi chiller 8, using lithium-bromide solution as absorption
Agent, water produce air adjustment or technique cold water, undertake the refrigerating capacity of Some gases source pump as refrigerant.
When the present invention works in the winter time：
1) winter heating of gas-burning machine heat pump unit 1 produces hot water supply air conditioner user (pipeline and auxiliary device configuration same summer
Season).
2) cooling water in engine flue gas heat regenerator 4 absorbs heat from engine flue gas heat regenerator 4, after heat user
The enclosed water storage tank 5 with coil heat exchanger 6 is back to, then engine flue gas heat regenerator is sent back to by recirculated water 10 and enters the circulation of 4 rows
Heating, domestic hot-water is heated and provided for user terminal.
3) when winter environment temperature is too low, the portion of gas engine cooling water and engine flue gas heat regenerator 4 is utilized
Heat is divided to improve the supply water temperature of winter gas-burning machine heat pump evaporator (the actual condenser for cooling in summer circulation), guarantee combustion gas
The machine heat pump Effec-tive Function under worst cold case in the winter time.When winter gas-burning machine heat pump evaporator, (actual is cooling in summer circulation
Condenser) recirculated water mixed with the cooling water (having absorbed engine exhaust heat) of engine after through detect water temperature still be not up to volume
During provisioning request, the bypass of electric T-shaped valve 15 is opened, and part recirculated water enters the enclosed water storage tank 5 with coil heat exchanger 6, passes through disk
Heat exchange of heat pipe 6 carries out heat exchange absorption with the heat user backwater in water tank (equivalent to the waste heat absorbed again in off-gas recovery device)
After heat heating, return directly feeds gas-burning machine heat pump evaporator (actual is cooling in summer cycle condenser).
