Abstract
A dual system energy-saving central air conditioner, which relates to an air conditioning system including both a water chiller refrigerating system and a refrigerant direct-evaporation refrigerating system, comprising an indoor unit, and outdoor unit and a connecting pipeline that links the indoor and outdoor units, characterized in that: the utility model combines two sets of air conditioning systems applying different refrigerating modes, i.e. a water chiller refrigerating system and a refrigerant direct-evaporation refrigerating system; an electronic control device IC1 is applied for unified control of the water chiller refrigerating system and the refrigerant direct-evaporation refrigerating system.
Description
The utility model belongs to filed of air conditioning.
The refrigeration modes of existing small central air conditioning has two kinds: the direct sweat cooling of cooling-water machine refrigeration system and cold-producing medium system.These two kinds of refrigeration systems respectively have pluses and minuses: the cold of cooling-water machine refrigeration system regulate and distribute all very flexible, convenient, but the pre-cool time of refrigeration system is longer, both water temperature dropped to operating temperature and needed the long time behind the system boot; Though the direct sweat cooling of cold-producing medium system refrigerating speed is fast, but the refrigerating capacity of its indoor set need be mated with compressor, be difficult for carrying out cold adjusting and distribution, carry out cold adjusting and distribution if desired, generally be cold to be distributed to each room with the air channel, as long as but have a room to need refrigeration in use, compressor will turn round, can not regulate cold output owing to decide the rotating speed compressor, the cooling amount is constant, so when the room of needs refrigeration negligible amounts, the energy of waste is more, though and the cold that uses converter technique that compressor is exported can be regulated, and cost is increased greatly.
The purpose of this utility model provides a kind of dual system energy-saving type central air-conditioning, and it is reached: 1, both can fast-refrigerating, and can carry out cold again and regulate and distribute.2, the cooling amount can be regulated, and has significantly energy-conserving action.3, off-premises station occupy little space, easy for installation.
The technical solution of the utility model is as follows:
Dual system energy-saving type central air-conditioning is that the air-conditioning system with two kinds of different refrigeration modes is used in combination, it is characterized in that: outdoor unit is made up of the air-conditioning system of the different refrigeration modes of two covers, one cover is the direct sweat cooling of cold-producing medium system, another set of is the cooling-water machine refrigeration system, and by the unified control of electronic-controlled installation IC1.
The direct sweat cooling of cold-producing medium system comprises the room air conditioner composition of the use refrigerant medium in compressor, four-way change-over valve, air-cooled condenser, throttling arrangement and the indoor units, the suction tracheae of compressor all is connected with four-way change-over valve, and two other port of four-way change-over valve links to each other with room air conditioner with air-cooled condenser respectively.
The cooling-water machine refrigeration system comprises compressor, four-way change-over valve, air-cooled condenser, throttling arrangement, heat exchanger composition, the suction tracheae of compressor all is connected with four-way change-over valve, two other port of four-way change-over valve links to each other with the refrigerant side of air-cooled condenser and heat exchanger respectively, and the cold water side of heat exchanger links to each other with the room air conditioner that uses aqueous medium with water pump.
Electronic-controlled installation IC1 unified control cooling-water machine refrigeration system and the direct sweat cooling of cold-producing medium system.
The utlity model has following advantage:
1, owing to overlap in the air-conditioning equipment, comprised the air-conditioning systems of the different refrigeration modes of two covers one,
Be the direct sweat cooling of cooling-water machine refrigeration system and cold-producing medium system, during installation with cold-producing medium
Directly the indoor units of sweat cooling system be installed in need fast cooling the room (as the visitor
The Room), the fast advantage of performance cold-producing medium direct sweat cooling system's refrigerating speed; Cold water mechanism
The indoor units of cooling system is installed in respectively in remaining a plurality of room, performance cold water mechanism
The cooling system cold is regulated and is distributed all very flexible, advantage easily.Remedy mutually, make the best use of the advantages
Keep away weak point.
2, the indoor units of the direct sweat cooling of cold-producing medium system is installed in needs soon in the utility model
The room of prompt drop temperature (as the parlor), when this room need freeze, compressor operating, this room
Between when not needing to freeze, compressor does not move, thereby has avoided energy dissipation, has better
Energy-saving effect.3, the utility model is outdoor owing to the air-conditioning systems with the different refrigeration modes of two covers are installed in a cover
In the unit, can significantly reduce the volume of its assembling, it is occupied little space.Thereby save
Installing space makes installation more convenient.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is a structural principle schematic diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
As Fig. 1, and cooperate shown in Figure 2ly, indoor section 3 comprises one or more room air conditioner 20 that uses aqueous medium in the utility model, one or more uses the room air conditioner 2 and the indoor attemperating unit 1 of refrigerant medium; Off-premises station 9 comprises the off-premises station 12 of cooling-water machine refrigeration system and the off-premises station 8 and the electronic-controlled installation IC1 of the direct sweat cooling of cold-producing medium system.
Among Fig. 1, the off-premises station 12 of cooling-water machine refrigeration system is formed complete refrigeration (heat) system of a cover by compressor (MC2) 15, four-way change-over valve (SV2) 11, condenser 14, fan (MF) 13, throttling arrangement 16 and plate type heat exchanger 17, cold (heat) amount is carried out heat exchange by plate type heat exchanger 17 and water, water pump (MS) 18 drives the aqueous medium circulation, in indoor section 3 one or more uses the room air conditioner 20 of aqueous medium to carry out heat exchange with room air, regulates indoor temperature.
Among Fig. 1, the off-premises station 8 of the direct sweat cooling of cold-producing medium system is made up of compressor (MC1) 5, four-way change-over valve (SV1) 6, condenser 7, fan (MF) 10, use the room air conditioner 2 of refrigerant medium to form complete refrigeration (heat) system of a cover with throttling arrangement 4 and one or more, in indoor section 3 one or more uses the room air conditioner 2 of refrigerant medium to carry out heat exchange with room air, regulates indoor temperature.
