Technical Field
The utility model relates to a filter equipment among ground source heat pump air conditioning system.
Background
A ground source heat pump air conditioning system relates to a large number of devices such as water pumps, heat pump main machines and the like which need Y-shaped filter protection. Each machine room needs nine Y-shaped filters in a small quantity, and needs dozens of Y-shaped filters in a large quantity. The Y-shaped filter is used for removing impurities in the medium so as to protect the water pump and normal use of equipment. However, the Y-filter is clogged over a long period of time, so that the Y-filter needs to be cleaned periodically, especially in the early stage of a newly built air conditioning system, so as to keep the whole system clean. Fig. 1 is a conventional Y-type filter structure, which includes a main filtering pipe 1 and a side filtering pipe 2 obliquely connected to the middle of the main filtering pipe 1; one end of the main filter tube 1 is a water inlet, the other end of the main filter tube 1 is a water outlet, and a cylindrical filter screen is arranged in the inner cavity of the side filter tube 2. When the filter screen in the filter is cleaned or replaced, the system is shut down, and then the valve 11 at the water inlet and the valve 12 at the water outlet of the main filter pipe 1 are closed. The shutdown of the whole system not only affects users, but also is not beneficial to the stability of the whole system operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect and provide a filter equipment among ground source heat pump air conditioning system, it can wash or change the filter screen when not interrupting the air conditioning system operation to system operation's stability has been kept.
The purpose of the utility model is realized like this: a filtering device in a ground source heat pump air conditioning system comprises a first Y-shaped filter, a second Y-shaped filter, an inlet tee joint and an outlet tee joint; the first Y-shaped filter and the second Y-shaped filter both comprise a main filter pipe and a side filter pipe obliquely connected to the middle part of the main filter pipe, one end of the main filter pipe is a water inlet, the other end of the main filter pipe is a water outlet, a filter cavity is arranged in the side filter pipe, and a filter screen is arranged in the filter cavity; wherein,
the main filter tube of the first Y-shaped filter is parallel to the main filter tube of the second Y-shaped filter;
two ports of the inlet tee joint are respectively connected with a water inlet of the first Y-shaped filter and a water inlet of the second Y-shaped filter in a one-to-one correspondence manner through a first inlet valve and a second inlet valve, and the other port of the inlet tee joint is connected with an upstream pipeline of the filtering device;
two ports of the outlet tee joint are respectively connected with the water outlet of the first Y-shaped filter and the water outlet of the second Y-shaped filter in a one-to-one correspondence mode through the first outlet valve and the second outlet valve, and the other port of the outlet tee joint is connected with a downstream pipeline of the filtering device.
The utility model discloses a filter equipment among the earth source heat pump air conditioning system has following characteristics: through two filters which are arranged in parallel and valves are respectively arranged at the water inlets and the water outlets of the two filters, the filter screen can be cleaned or replaced without interrupting the operation of the air-conditioning system through the switching of judicial valves, thereby maintaining the stability of the operation of the system.

fig. 2 is a schematic structural diagram of the filtering device in the ground source heat pump air conditioning system of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 2, the filtering apparatus of the ground source heat pump air conditioning system of the present invention includes a first Y-shaped filter 10, a second Y-shaped filter 20, an inlet tee 30 and an outlet tee 40; the first Y-shaped filter 10 and the second Y-shaped filter 20 both comprise a main filter pipe and a side filter pipe obliquely connected to the middle part of the main filter pipe, one end of the main filter pipe is a water inlet, the other end of the main filter pipe is a water outlet, a filter cavity is arranged in the side filter pipe, and a filter screen is arranged in the filter cavity;
the main filter tube of the first Y-shaped filter 10 is arranged in parallel with the main filter tube of the second Y-shaped filter 20;
two ports of the inlet tee 30 are respectively connected with the water inlet of the first Y-shaped filter 10 and the water inlet of the second Y-shaped filter 20 through a first inlet valve 51 and a second inlet valve 52 in a one-to-one correspondence manner, and the other port of the inlet tee 30 is connected with an upstream pipeline of the filtering device;
two ports of the outlet tee 40 are respectively connected with the water outlet of the first Y-shaped filter 10 and the water outlet of the second Y-shaped filter 20 through a first outlet valve 61 and a second outlet valve 62 in a one-to-one correspondence manner, and the other port of the outlet tee 40 is connected with a downstream pipeline of the filtering device.
The utility model discloses a filter equipment among ground source heat pump air conditioning system, when normal operating, all open first inlet valve 51, second inlet valve 52, first outlet valve 61 and second outlet valve 62, make first Y type filter 10 and second Y type filter 20 simultaneous workings.
