Description
Technical field
The utility model belongs to the air-conditioner technical field, more specifically to the improvement of frequency conversion one-to-one air-conditioner.
Background technology
The one-to-one air-conditioner is to drag an indoor set with an off-premises station.The configuration of existing off-premises station has two kinds of situations substantially.A kind of is only to dispose an invariable frequency compressor.The advantage of this configuration is that the low price cost is low.Shortcoming is that the capacity (capacity) and (heat) amount of freezing are fixing, and indoor temperature change generated in case is big, the startup power consumption is big, noise is big because of the compressor chamber disconnection stops causing.Another kind is only to dispose a frequency-changeable compressor.The advantage of this configuration is: capacity (capacity) and refrigeration (heat) amount all change pro rata continuously with frequency; Can under lower rotating speed, start compressor, so starting current is little, the startup power consumption is little, noise is low; Can in time change operating mode according to desired room temperature after the startup, thereby reach requirement very soon, the temperature comfortableness is good, energy savings, and noise is low.Its shortcoming is the expensive cost height of price, is difficult to accept for most of users.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, provides a kind of and both can make the compressor variable frequency varying capacity, reduce and start power consumption and noise, can in time adjust operating mode and reach requirement very soon according to desired room temperature again, the temperature comfortableness be good, energy savings; And lower price is arranged again, can be the multi-compressor varying capacity frequency conversion one-to-one air-conditioner that most of user accepted.
Summary of the invention
In order to achieve the above object, the utility model is by compressor, the check valve that is connected with the blast pipe of compressor, the four-way change-over valve that is connected with check valve with pipeline, the off-premises station heat exchanger that is connected with four-way change-over valve with pipeline, the electric expansion valve that is connected with the off-premises station heat exchanger with pipeline, the high-pressure stop valve that is connected with electric expansion valve with pipeline, the heat exchanger indoor unit that is connected with high-pressure stop valve with pipeline, the low-pressure shutoff valve that is connected with heat exchanger indoor unit with pipeline, gas-liquid separator that is connected with low-pressure shutoff valve through above-mentioned four-way change-over valve with pipeline and the air inlet pipe that connects gas-liquid separator and compressor are formed.Compressor is in parallel more than 2 or 2, wherein has at least one to be frequency-changeable compressor.The blast pipe of all compressors connects a check valve separately, and each pipeline that is connected with each check valve is connected with four-way change-over valve after converging again.Every compressor has an air inlet pipe to be connected with gas-liquid separator.
Compressor can be 2, its capacity (capacity) small one and large one, wherein one is frequency-changeable compressor.Compressor also can be 2, wherein has one to be frequency-changeable compressor, and the capacity of two compressors (capacity) equates.During work, when needing fast-refrigerating (heat), all compressors can be opened simultaneously, the increase capacity reaches the purpose of quick temperature adjustment.When indoor temperature reaches requirement, can only open the compressor insulation of suitable capacity, with energy-conservation as much as possible.During start, then can make full use of the advantage of frequency-changeable compressor,, under lower rotating speed, carry out, reduce starting current and start power consumption and noise with the less frequency-changeable compressor of capacity.
Compressor also can be 3, wherein has at least one to be frequency-changeable compressor, and the capacity of 3 compressors (capacity) has nothing in common with each other.Compressor also can be 3, wherein has one to be frequency-changeable compressor, and the capacity of other two invariable frequency compressors (capacity) is identical.When compressor was 3, frequency-changeable compressor wherein can have three kinds of situations of one, two, 3.The capacity of 3 compressors (capacity) can suitably be arranged in pairs or groups as required.
Compressor also can be more than 4 or 4, wherein has at least one to be frequency-changeable compressor.The capacity of compressor (capacity) can suitably be arranged in pairs or groups as required.
After number of compressors increased, the possible mode of its temperature and duty control increased, and capacity control progression from small to large increases in other words.Effect was best when compressor was 2 or 3,4 or can satisfy the needs in some big place more for a long time.
The utility model has been finished the task of varying capacity frequency conversion off-premises station with the reasonable combination of frequency-changeable compressor and invariable frequency compressor.Both the variable ratio frequency changer varying capacity reduced and started power consumption and noise, can in time adjust various working according to desired room temperature, and the temperature comfortableness is good, energy savings; Lower price is arranged again, can be accepted, be suitable for popularization by most of users.It can be widely used in the places such as family, office building, hotel, enterprises and institutions.
