Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The first embodiment is as follows:
as shown in fig. 1-2, the present embodiment provides a gas heat pump system, which includes an engine 5 and a refrigeration system, where the refrigeration system includes a compressor 1, a condenser 2, a throttling component 3, and an evaporator 4, which are sequentially connected and form a loop, and the engine 5 is in transmission connection with the compressor 1 through a belt.
In the present embodiment, the pulley of the engine 5 includes a small pulley 11 and a large pulley 12 which are coaxially disposed, the pulley of the compressor 1 includes a first pulley assembly 6 and a second pulley assembly 7 which are coaxially disposed, and the first pulley assembly 6 and the second pulley assembly 7 are oppositely disposed on the transmission shaft of the compressor 1.
In this embodiment, the first pulley assembly 6 includes a first clutch chuck 8, a first pulley 9 and a first electromagnetic coil 10, a groove is disposed on one side of the first pulley 9, the first electromagnetic coil 10 is embedded into the groove, the first clutch chuck 8 is disposed on the other side of the first pulley 9, and the middle of the first clutch chuck 8 is connected to the transmission shaft of the compressor 1.
In this embodiment, the second pulley assembly 7 includes a second clutch chuck 13, a second pulley 14 and a second electromagnetic coil 15, a groove is disposed on one side of the second pulley 14, the second electromagnetic coil 15 is embedded in the groove, the second clutch chuck 13 is disposed on the other side of the second pulley 14, and the middle of the second clutch chuck 13 is connected to the transmission shaft of the compressor 1.
The first pulley assembly 6 and the second pulley assembly 7 can be used for switching on or off the power transmission between the engine 5 and the compressor 1, and meanwhile, when the compressor 1 is overloaded, the first pulley assembly 6 and the second pulley assembly 7 can also play a certain protection role.
In this embodiment, when the first clutch chuck 8 and the first pulley 9 are attracted to each other, the second clutch chuck 13 and the second pulley 14 are away from each other;
when the second clutch sucker 13 and the second belt pulley 14 are mutually sucked, the first clutch sucker 8 and the first belt pulley 9 are mutually far away.
Specifically, when the first electromagnetic coil 10 of the first pulley assembly 6 is energized, the first electromagnetic coil 10 generates electromagnetic suction force to adsorb the first clutch sucker 8 onto the first belt pulley 9, and since the first belt pulley 9 and the large belt pulley 12 of the engine 5 rotate synchronously, the first belt pulley 9 drives the first clutch sucker 8 to rotate together, the first clutch sucker 8 transmits power to the compressor through a transmission shaft connected to the first clutch sucker 8, and the compressor starts to work; at this time, the second electromagnetic coil 15 of the second pulley assembly 7 does not pass electricity, and the second pulley 14 idles, and does not affect the operation of the first pulley assembly 6.
In the present embodiment, the first belt pulley 9 of the first belt pulley assembly 6 is in belt transmission connection with the large belt pulley 12, and the second belt pulley 14 of the second belt pulley assembly 7 is in belt transmission connection with the small belt pulley 11.
In the present embodiment, since the diameters of the first pulley assembly 6 and the second pulley assembly 7 are the same, and the diameter of the small pulley 11 is smaller than the diameter of the large pulley 12, the transmission ratio between the first pulley assembly 6 and the large pulley 12 is larger than the transmission ratio between the second pulley assembly 7 and the small pulley 11.
The present embodiment can switch the two power transmission paths at different loads to adjust the gear ratio.
Specifically, when the air conditioning output demand is large, the second pulley assembly 7 switches the power transmission between the engine 5 and the compressor 1, the first pulley assembly 6 switches on the power transmission between the engine 5 and the compressor 1, and at this time, the first pulley assembly 6 starts to operate, and at the same engine 5 rotation speed, because the transmission ratio is larger, the rotation speed of the compressor 1 is larger, and the upper rotation speed limit of the compressor 1 is also higher.
When the output requirement of the air conditioner is small, the second belt pulley assembly 7 is switched to work, and the rotating speed of the compressor 1 is smaller and the lower limit of the rotating speed of the compressor 1 is also lower at the same engine rotating speed because the transmission ratio is smaller.
The embodiment has a simple structure, can realize the function which can be realized by a plurality of compressors in the prior art only by one compressor, and has lower cost and lower failure rate than the prior art.
Example two:
the present embodiment differs from the embodiment in that: in this embodiment, the diameter of the first pulley assembly 6 is larger than the diameter of the second pulley assembly 7.
Specifically, the diameter of the first pulley assembly 6 is greater than that of the second pulley assembly 7, and the diameter of the large pulley 12 is also greater than that of the small pulley 11, so that the first pulley assembly 6 is connected with the large pulley 12 through belt transmission, and the second pulley assembly 7 is connected with the small pulley 11 through belt transmission.
Therefore, the transmission ratio of the power path connecting the first pulley assembly 6 and the large pulley 12 is much greater than the transmission ratio of the power path connecting the second pulley assembly 7 and the small pulley 11, and the rotation speed of the compressor 1 is also much greater when the first pulley assembly 6 is operated.
In the embodiment, the range of the transmission ratio is increased by arranging the first belt pulley assembly 6 and the second belt pulley assembly 7 with different diameters, so that the transmission ratio is larger when the first belt pulley assembly 6 works, and the transmission ratio is smaller when the second belt pulley assembly 7 works.
