Embodiment 1

[0039] see diagram 2-1 , Figure 2-2 , Figure 3-1 and Figure 3-2 , on the basis of the structure of the original four-way valve, the pipe S is removed, the pipe S is closed with the tube root 6-8-1 of the valve body 8, and becomes a part of the valve body 6-8, the outlet end s of the capillary s -1 is the connection end with the suction pipe of the air conditioner compressor, the D pipe is the refrigerant inlet pipe, and the refrigerant outlet pipes are only the C pipe and the E pipe, so it becomes a three-way valve with one inlet and two outlets. In other words, on the basis of the structure of the original four-way valve, no S pipe is made, and the outlet end s-1 of the capillary s is connected to the suction pipe of the air-conditioning compressor. Through the above improvements, the original four-way valve becomes an electromagnetic three-way valve, which can be used as a solenoid valve in an air conditioner, or used as a solenoid valve in a hot water air conditionin...

Embodiment 2

[0041] The S tube of the existing four-way valve can be retained and sealed by welding, or connected with a screw cap and a seal, so that the S tube is closed, and the outlet end s-1 of the capillary tube s is connected to the suction tube of the air conditioner compressor. connection end. Although the S tube is retained like this, because it is closed, the refrigerant cannot flow out. Similarly, the D pipe is the refrigerant inlet pipe, and the refrigerant outlet pipe is still only the C pipe and the E pipe, thus becoming a three-way valve with one inlet and two outlets.

[0042] see Figure 4 , which is a system diagram of the application of the improved three-way valve 6 of the four-way valve in hot water air conditioning. The hot water air conditioning system includes a compressor 1, a four-way valve 8, a condenser 13, an evaporator 21, a water heater module 30, a plurality of one-way valves, capillary tubes, a four-way valve improved three-way valve 6, and a refrigerant...

Abstract

The invention provides a three-way valve improved by utilizing an air-condition four-way valve, a hot-water air-conditioning system and an air conditioner. The problems of high cost of a plurality of solenoid valves, poor reversing performance and the like existing in the prior art can be solved. The technical scheme is that: the three-way valve comprises a solenoid coil, a pilot slide valve, a spring, a capillary tube c, a capillary tube d, a capillary tube e, a capillary tube s, a valve body, a piston cavity, a left piston, a right piston, a main slide valve, a C pipe, an E pipe and a D pipe, wherein the D pipe is a refrigerant inlet pipe; an outlet end of the capillary tube s is connected with an air suction pipe of an air condition compressor; and refrigerant outlet pipes only comprise the C pipe and the E pipe. The three-way valve improved by adopting the air-condition four-way valve is used for controlling the flow direction of refrigerating fluid, is switched on or switched off in a circulation of preparing heat water and non-preparing heat water, and replaces a plurality of solenoid valves in the prior art, so that the cost of the solenoid valves is reduced by at least 70 percent, the control is simplified, the leakage of the refrigerating fluid due to lax closure of the solenoid valves under high pressure difference is avoided, and the reliability in operation of an air-conditioning system is improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration engineering in the field of energy, and in particular relates to a waste heat utilization system of an air-conditioning system, a hot-water air-conditioning system directly heated by a refrigerant of a solenoid valve replaced by a three-way valve improved by a four-way valve. Background technique [0002] see figure 1 , which is the existing hot water air conditioning system diagram. From figure 1 It can be seen from the figure that the existing air conditioners with hot water heating must use the solenoid valve 6 and the solenoid valve 9 in the hot water heating or non-hot water heating mode. When hot water needs to be heated, the solenoid valve 6 should be closed, and the solenoid valve 9 should be in an open state. When hot water heating is not needed, the electromagnetic valve 9 is closed, and the electromagnetic valve 6 is in an open state. Therefore, only two e...
