The frequency converting control type integrated water source cabinet type air conditioner is characterized in that the compressor is a frequency converting compressor, a frequency converting control circuit board is arranged in the compressor, the frequency converting control circuit board comprises a frequency converter, a rectifier and a microprocessor, and the frequency converter is electrically connected with the rectifier which is electrically connected with an alternating-current power supply. The frequency converting control type integrated water source cabinet type air conditioner has the advantages that integrated design is achieved, the structure is simple, mounting is convenient, the service life of the compressor is prolonged, meanwhile, cooling and heating speed is high, seasonal electricity saving is obvious, the air conditioner can be adaptive to a wide environment temperature range, and silence, high efficiency and energy saving are achieved.
Description
technical field:
The utility model relates to one water source cabinet air-conditioner, particularly a kind of VFC type one water source cabinet air-conditioner.
background technology:
Air-conditioning is a kind of for the unit of processing air is provided to area of space (being generally airtight).It can regulate the parameters such as temperature, humidity, cleanliness factor and air velocity of the interior air in this room (or enclosure space, region), to meet the requirement that human body is comfortable.Raising along with people's environmental consciousness, on market, there is one water source cabinet air-conditioner, utilize the water sources such as underground water or river to replace the air-conditioner of the needed freon refrigerant of conventional air conditioner, but the life-span that there is compressor is short, the slow and shortcoming such as power consumption relatively of cooling and warming speed.
utility model content:
The utility model is mainly the automatically controlled control for one water source cabinet air-conditioner, frequency conversion control technique is implanted in one water source cabinet air conditioner, overcome the defect of prior art, provide a kind of and extend the compressor life-span, cooling and warming speed is fast and the VFC type one water source cabinet air-conditioner of efficient energy-saving.
The technical scheme that realizes above-mentioned technical purpose is, a kind of VFC type one water source cabinet air-conditioner, comprise cabinet, air outlet, side return air inlet, be arranged on finned evaporator, compressor, centrifugal blower, cross valve, throttle part and small-sized shell and tube exchanger in cabinet, it is characterized in that: described compressor is frequency-changeable compressor, in described compressor, be provided with frequency conversion control circuit plate, described frequency conversion control circuit plate has comprised frequency converter, rectifier and microprocessor.
Further, described frequency converter is electrically connected to rectifier, and described rectifier is electrically connected to AC power.
The beneficial effects of the utility model: integral type design, simple in structure and easy for installation; Introduce Frequency Converter Control technology; household air-conditioner is further improved; during use, temperature fluctuation is little; insensitive to mains fluctuations; after compressor start, generally do not shut down, avoid high frequent start-stop; extended the life-span of compressor, have simultaneously fast, the seasonal power saving of cooling and warming speed obviously, more extensive, quiet, efficient, the energy-conservation feature of the temperature that conforms.
accompanying drawing explanation:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation.
The name of the Reference numeral in above-mentioned accompanying drawing is called:
1-cabinet, 2-air outlet, 3-side return air inlet, 4-finned evaporator, 5-centrifugal blower, 6-cross valve, 7-compressor, 8-throttle part, the small-sized shell and tube exchanger of 9-, 10-water pump, 11-frequency conversion control circuit plate, 12-frequency converter, 13-rectifier, 14-microprocessor, 15-AC power.
the specific embodiment:
As shown in Figure 1, this specific embodiment is by the following technical solutions: a kind of VFC type one water source cabinet air-conditioner, comprise cabinet 1, air outlet 2, side return air inlet 3, be arranged on the finned evaporator 4 in cabinet, compressor 7, centrifugal blower 5, cross valve 6, throttle part 8 and small-sized shell and tube exchanger 9, it is characterized in that: described compressor 7 is frequency-changeable compressors, in described compressor 7, be provided with frequency conversion control circuit plate 11, described frequency conversion control circuit plate 11 has comprised frequency converter 12, rectifier 13 and microprocessor 14, described frequency converter 12 is electrically connected to rectifier 13, described rectifier 13 is electrically connected to AC power 15.
The operation principle of VFC is that power frequency AC 15 is converted to dc source, and it is delivered to power model (high power transistor switch combination), the control signal that module is sent here by microprocessor 14 is simultaneously controlled, the alternating source 15 that output frequency is adjustable (synthetic waveform near sinusoidal ripple), make compressor 7 motor speeds of one water source cabinet air-conditioner do corresponding variation with the variation of supply frequency, thereby control the discharge capacity of compressor 7, regulate refrigerating capacity and the heating capacity of one water source cabinet air-conditioner.
VFC is mainly controlled the rotational frequency of compressor 7 by controlling other electric elements such as rectifier 13, frequency converter 12, thereby reach the object that one water source cabinet air-conditioner is controlled indoor temperature flexibly, frequency converter 12 can make the rotating speed stepless continuous of compressor 7 motor adjustable, and its rotating speed is according to the proportional variation of indoor temperature.When needs freeze, compressor 7 frequency rising faster rotational speed, refrigerating capacity just increases in proportion, and when reaching design temperature, compressor 7 reduces frequency immediately, and in low-speed running state, to maintain indoor temperature substantially constant.When needs heat, be also in like manner.
