Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of low form combustion-gas thermal pump air-conditioning system, including exchanged heat by compressor 2, oil eliminator 4, four-way valve 5, indoor unit
Device 13, outdoor unit heat exchanger 6 and gas-liquid separator 3 sequentially connect and the refrigerant circulation circuit that constitutes, specifically: compressor 2
Exhaust outlet is successively connected to indoor set heat exchanger 13 after oil eliminator 4 and four-way valve 5, using outdoor unit heat exchanger 6, four
After port valve 5 and gas-liquid separator 3, it is connected to the air entry of the compressor 2, forms complete refrigerant circulation circuit.Wherein, institute
Outdoor unit heat exchanger 6 is stated equipped with outdoor unit electric expansion valve 7.The indoor set heat exchanger 13 can be multiple parallel connections, and each
An electronic expansion valve of indoor unit 12 is equipped on indoor set heat exchanger, convenient for flexibly control.
The compressor 2 is connected by belt with gas engine 1, is moved to obtain by what the gas engine 1 generated
Power.The outside of the gas engine 1 is equipped with cooling water tank 15, contains cooling water in the cooling water tank, can start to the combustion gas
Machine 1 is cooled down in time.The cooling water tank 15 constitutes cooling water with the first radiator 9 and the second radiator 11 by water pump 14 and follows
Loop back path can make the cooling water after being heated by cooling down in first radiator 9 or the second radiator 11, then flow again
It is reused after returning the cooling water tank 15, energy conservation and environmental protection.First radiator 9 and the second radiator 11 are in parallel, and institute
The one end for stating the first radiator 9 is equipped with the first solenoid valve 8, and one end of second radiator 11 is equipped with second solenoid valve 10, energy
Enough on-off for controlling each radiator respectively, efficiently use heat entrained by the cooling water.
First radiator 9 is arranged side by side with the outdoor unit heat exchanger 6, and in close proximity to, its spacing 0-5mm,
It can make effectively to exchange heat between the two.Second radiator 11 is set to the side of the outdoor unit heat exchanger 6, can be with institute
State the perpendicular setting of the first radiator or other apart from 6 remote position of outdoor unit heat exchanger, so that air-conditioning is in system
When cold mode, the heat dissipation of second radiator will not influence the heat dissipation effect of the outdoor unit radiator.Its carrying out practically process
Are as follows:
1. the first solenoid valve is opened when system heating operation, second solenoid valve is closed, at this point, the cooling water in cooling water tank
Absorb gas engine generation heat and temperature with higher, flowed through under the action of water pump the first radiator carry out it is scattered
Heat.At this point, outdoor unit heat exchanger needs to absorb heat just, and the first radiator and outdoor unit heat exchanger close-packed arrays, make the two energy
Enough sufficiently progress heat exchanges make the energy be fully used so as to greatly improve the heating efficiency of system.
2. the first solenoid valve is closed when cooling system operation, second solenoid valve is opened, and cooling water is transported to second
It radiates in radiator.And second radiator is located outside the side of machine heat exchanger, makes to generate between the two mutually
It influences, it is ensured that unit trouble-free operation.
3GPH88 can be selected in the gas engine 1.The compressor 2 can select GHP5212MY2.
The present invention is by being arranged multiple cooling water radiators, and comparing ensures that cooling water obtains effective temperature-reducing, moreover, can also fill
Point using the heat entrained by it, the heating efficiency of system is improved, energy efficiency is worthy to be popularized.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
