By this accumulation of heat application system can control this heat pipe-type regenerative apparatus realize accumulation of heat, supply when storing, heat release etc. no With operating condition, each operating condition and and corresponding control logic be described as follows:
1. low ebb electric heat storage operating mode:
Under the operating mode, electric heater is in running order, and circulating pump is in halted state, motor-driven valve V1, motor-driven valve V2, electricity Dynamic valve V3, motor-driven valve V4 are closed.During trough-electricity, electric heater 205 starts and passes through electric heating heat exchange of heat pipe 2 Accumulation of heat groove body 1 is heated, when being heated to accumulation of heat set temperature, the temperature sensor feedback in groove body 1 cuts off electricity to controller The electric heater 205 in source, electric heating heat exchange of heat pipe 2 stops heating;Wherein it is possible to regenerator temperature is set as 115 degree, so as to energy Larger amount of stored heat is enough obtained, while groove body 1 being avoided to be defined as pressure vessel again, inspection cost is manufactured and supervise to reduce.Work as accumulation of heat When pressure in groove body 1 is more than the maximal pressure force value of setting, pressure sensor feeds back to controller and cuts off the power, and electric heating heat pipe changes The electric heater 205 of hot device 2 stops heating, while controller carries out fault alarm, to play the role of safeguard protection;Work as pressure value More than safety valve setting limiting pressure when, pressure release is opened and carried out to controller control safety valve, while controller progress failure Alarm, and cut off the power, the electric heater 205 of electric heating heat exchange of heat pipe 2 stops heating.
When system is in this operating mode, motor-driven valve V1, motor-driven valve V2 and motor-driven valve V3, motor-driven valve V4 are in closing shape State, circulating pump are also at halted state, and electric heater 205 carries out continuous heating to heat-accumulator tank.
2. when storing for operating mode:
Under the operating mode, electric heater and circulating pump are in running order, and motor-driven valve V2, motor-driven valve V4, which are in, to be opened or adjust State, motor-driven valve V1, motor-driven valve V3 are closed.3 interior media of heat release coil pipe under this operating mode in accumulation of heat groove body 1 Medium by motor-driven valve V1, motor-driven valve V3 cut-out, become heat pipe-type regenerative apparatus and heat release coil pipe+circulating pump+heating terminal The two separate systems, and identical pressure is set as by constant pressure arrangement.When accumulation of heat needs heat supply simultaneously, such as It heats at night for house, needs to use this operating mode.At this moment the startup of electric heater 205 is simultaneously right by electric heating heat exchange of heat pipe 2 Accumulation of heat groove body 1 heats, meanwhile, as a part for heat release coil pipe 3, upper header 202 and the heat release disk of heat pipe type electric heater 205 The water at low temperature that heating terminal is returned is heated as high-temperature water by pipe 3 together, is realized externally for hot function, and at this moment, accumulation of heat groove body 1 adds Control logic of the control logic of heat with low ebb electric heat storage operating mode.When heat release, the return water of heating terminal enters by motor-driven valve V2 Heat release coil pipe is entered circulating pump suction inlet in the upper header of electric heating heat exchange of heat pipe and heat storage tank body after high-temperature medium heating, Heating terminal heat release is transported to by circulating pump.When the load of heating terminal is less than normal, when thermal discharge is excessive, motor-driven valve V2 can be passed through It turns down, reduces the method for heat release coil pipe pipeline flow to reduce the thermal discharge of heat pipe-type regenerative apparatus, while adjusting motor-driven valve V4 Size control heating terminal low-temperature return water flow, so as to while meeting heating terminal heating load and needing control to heating The heat supply temperature of end.When the load of heating terminal is bigger than normal, when thermal discharge is too small, can be opened by motor-driven valve V2 greatly, increase is put The method of hot coil pipeline flow increases the thermal discharge of heat pipe-type regenerative apparatus, while the size control for adjusting motor-driven valve V4 is adopted The low-temperature return water flow of warm end short circuit, to control the confession to heating terminal while meeting heating terminal heating load and needing Hot temperature.When this accumulation of heat application system is in heat-accumulating process, when needing orderly heating, it is also desirable to use above-mentioned operating mode.
