Description
Technical field
The present invention relates to the relevant engineering science of cold air conditioning pressure regulating system.
Background technique
What air-conditioning and chiller plant adopted at present all is the compressed air refrigeration system.Most equipment all is made of 3 major components: 1) compressor, what 2) be installed in controlled temperature indoor (hereinafter to be referred as " indoor ") usually heats coil system (condenser or condenser coil) and cooling coil system (vaporizer or cooling coil), 3) thermostat or temperature controller, the machine operation of control compressor.When room temperature reached the predefined temperature of user, motor temporarily shut down; Otherwise as long as room temperature fails to keep the predefined temperature of user, motor will remain in operation.Compressor is an important mechanical device, and it can be delivered to whole system with compression cold oil stream, and oily stream is the lower compound of boiling point.Through after the cooling coil system, low-pressure low-temperature steam is inhaled into compressor compresses becomes high-pressure and high-temperature steam, and is discharged into and heats in the coil system, then enters the pipe-line system circulation of starting working.Through after heating coil system, the flow of liquid that above-mentioned oily stream becomes high pressure-temperature enters the cooling coil system through capillary tube, and in the cooling coil internal system, this oil stream is transformed into low-pressure low-temperature steam again and is inhaled into compressor once more.
In certain period, motor can be subjected to thermostat control and be in halted state.Can cause that like this oil pressure in the refrigeration system descends gradually.The intrasystem high pressure, high temperature liquid of cooling coil can constantly be flashed to the steam of low-pressure low-temperature because of high temperature and be gone into indoor side by side.At this moment, the high pressure, high temperature liquid that constantly pours in can merge with the vapor phase that before has been cooled.The latent heat of Chan Shenging can hinder oil stream and is transformed into steam fully in this case.If oil stream is not transformed into steam fully, will influence indoor temperature can't be stabilized on the predefined value for a long time.Therefore, compressor just must keep operating condition in unnecessary, and that is to say needs to keep long height running as commercial running.Like this, the oil that does not change into steam fully fails to be convened for lack of a quorum and damages the suction control valve of compressor, and therefore, it is very risky that compressor is badly damaged.Keep temperature to be stabilized in for a long time on the predefined value, can produce great energy waste problem, especially keep the compressor lost motion and the electric power wasted.The operation process of compressor has caused the waste of becoming estranged of many unnecessary energy flows.
Afterwards, in frequency conversion system, the motor of compressor adopted the low speed circulatory system to solve the problem that is stabilized in predetermined temperature value for a long time.But this way is also unsuccessful.Reason is that though the frequency conversion system full-speed operation can maintain on this temperature value after reaching the predefined temperature value of user for a long time, the electric power energy that the low speed circulatory system of frequency-changeable compressor consumes between on-stream period is still very big.This shows that promptly allow to keep the required temperature value of user, the energy waste but unnecessary energy flow is become estranged in the operation process still exists, the problems referred to above are not still solved at all.In addition, if the BTU of frequency-conversion air-conditioning system design is also bigger than the size in its room, place, this frequency conversion system is exactly in rain substantially so.
For addressing the above problem, the invention provides a special safety check as pressure control valve device-high pressure bypass valve equipment, it is a discoid valve device, be used in air-conditioning or the air cooling system and produce pressure regulating system, it can be when compressor be subjected to thermostat control to be in halted state, the high-pressure and high-temperature steam shape cold oil that the blocking-up compressor is discharged.So just produced pressure regulating system in air-conditioning inside.The pressure regulating system that the said equipment produced can be kept this temperature levels for a long time after the compressor full-speed operation reaches the predefined temperature value of user, and the rational Application electric power energy, does not produce wasting phenomena.
