The accompanying drawing explanation
Fig. 1 is that the water temperature of the utility model frequency conversion drive is regulated the machine fundamental diagram.
embodimentbelow in conjunction with preferred embodiment, be described in detail
A kind of water temperature of frequency conversion drive is regulated machine, as shown in Figure 1, comprises DC frequency-changeable compressor 1, cross valve 2, air-cooled heat exchanger 3, restricting element 4 and is placed in the oil-to-water heat exchanger 5 in water tank.The coil pipe of described air-cooled heat exchanger 3 is communicated with the coil pipe of water heat exchanger 5 by restricting element 4.Described cross valve 2 connects respectively blast pipe and muffler, the coil pipe of air-cooled heat exchanger 3 and the coil pipe of water heat exchanger 5 of DC frequency-changeable compressor 1.Described restricting element 4 can be capillary, restriction sleeve, electric expansion valve or two-way heating power expansion valve etc.When water temperature is regulated machine restricting element employing electric expansion valve, the VFC intralamellar part increases port and is connected with the electronic expansion valve controls end, can, according to temperature difference automatic control flow, allow machine that most suitable refrigeration (heating) coupling is arranged all the time; .When restricting element adopts capillary, according to the specified standard configuration frequency of frequency-changeable compressor, refrigerating capacity and the best state of power, determine capillary pipe length.Refrigerant adopts R410A, and R410A belongs to the environmental protection refrigerant, more meets global environmental protection concept.
On DC frequency-changeable compressor exhaust outlet, air-cooled heat exchanger coil pipe, on the oil-to-water heat exchanger coil pipe and be provided with temperature sensor in water tank, each temperature sensor is electrically connected to the VFC plate.The VFC plate is the interior water temperature T 4 of Sampling Compression machine exhaust outlet temperature T 1, air-cooled heat exchanger coil temperature T2, oil-to-water heat exchanger coil temperature T3 and water tank respectively.
The effect of Sampling Compression machine exhaust outlet temperature T 1: when the compressor high frequency rotates, delivery temperature constantly raises, and in the compressor operating process, if delivery temperature is greater than design temperature as 120 ℃, compressor frequency is too high must stoppage protection.
The effect of sampling air-cooled heat exchanger coil temperature T2: 1, under heating mode, frosting situation when judgement water temperature regulation mechanism is hot, controlled fan, cross valve and compressor respectively automatically in conjunction with the control panel program, controls in real time the defrost situation; 2, under refrigeration mode, realize air-cooled heat exchanger coil pipe high temperature protection function, when when refrigeration the condenser coil temperature higher than design temperature as 70 while spending, hard stop; The condenser coil temperature lower than design temperature as 50 degree after, trouble shooting.
