Problems solved by technology

[0003] Similar devices currently on the market are mechanical condensing pressure regulating valves. If you want to adjust the pressure of the heat pump system, you can only use a handwheel or wrench to rotate the valve handle by external force to change the spring tension in the mechanical valve to change the water flow into the heat exchanger. ;The mechanical condensing pressure valve is made of anti-rust heavy metal. It is large in size and heavy in weight. It must also be connected to the condensing system through a capillary tube. Depending on the pressure change of the heat pump system, the size of the water inlet channel in the mechanical condensing pressure valve is pushed to change the water flow rate. to adjust the high pressure of the heat pump system, it is extremely inconvenient to operate and install

Embodiment 1

[0044] In this embodiment, the heat pump is used as an example to produce hot water. First, set the temperature of the hot water to be produced and start the heat pump equipment. See figure 1 , the compressor 1 is energized to work, the compressed high-temperature and high-pressure refrigerant enters the electromagnetic four-way reversing valve 3 through the pipeline, and then enters the heat exchanger 4 in turn, exchanges heat with the water in the water pipe, and throttles the flow through the throttle valve 5 to reduce pressure. After passing through the evaporator 6 to absorb heat, passing through the electromagnetic four-way reversing valve 3, and then passing through the liquid reservoir 7, it returns to the compressor 1 for recompression and enters the next cycle.

[0045] Whether the auxiliary water inlet solenoid valve 13 is energized or not depends on the temperature value obtained by the exhaust temperature sensing package 2 of the heat pump. When the temperature val...

Abstract

The invention relates to an automatic condensing pressure regulating valve assembly. The condensing pressure regulating valve assembly comprises an exhaust temperature sensing bulb, a microprocessor and a regulating valve module; the exhaust temperature sensing bulb is arranged at an exhaust port of the compressor and obtains an exhaust temperature value in real time; a hot water temperature sensing bulb is arranged at a water outlet of a heat exchanger and obtains the water outlet temperature in real time; a regulating valve module is connected with a water inlet of the heat exchanger; the microprocessor is electrically connected with the exhaust temperature sensing bulb, an auxiliary water inlet electromagnetic valve and the regulating valve module; the microprocessor instructs the regulating valve module in real time according to the exhaust temperature value and / or the outlet water temperature, and the regulating valve module regulates and controls the water flow in real time according to a received instruction, so that the outlet water temperature of the heat exchanger tends to be stable. Compared with the prior art, electronic condensation pressure adjustment is adopted, and the target flow is set through the average flow in the period, so that oscillation in the adjustment and control process rapidly tends to be stable and does not greatly fluctuate up and down along with the change of the environment temperature.

Description

technical field [0001] The invention relates to the fields of regulating valves and heat pumps, in particular to an automatic condensing pressure regulating valve assembly. Background technique [0002] In the prior art, the condensing pressure regulating valve is generally installed on the cooling water pipeline of the condenser (usually installed at the water inlet end of the condenser), and adjusts the flow of cooling water according to the change of the condensing pressure. It adjusts the opening of the valve by directly sensing the pressure change of the refrigerant cycle to allow enough cooling water to flow through, which will save a lot of cooling water. When the refrigeration device is running, if the condensing pressure is too high, the discharge temperature of the compressor will rise; the compression ratio will increase; the cooling capacity will decrease; and the power consumption will increase. The higher the condensing pressure, the greater the above adverse ...
