Abstract
The utility model relates to a central air conditioner for family use, which is composed of a cold and hot water machine set, and an indoor machine set. The cold and hot water machine set comprises a compressor, a four-way reversing valve, an air-cooled condenser, a thermostatic expansion valve, a water tank and an evaporating pipe. The indoor machine set comprises a fan and a heat exchanger which is communicated with the water tank. The utility model is suitable for being used at areas with hard water quality. The utility model has the advantages of good heat exchange effect, high effectiveness ratio, low cost, etc.
Description
The utility model belongs to filed of air conditioning, relates in particular to the central air conditioner that family uses.
Current domestic air conditioner, fenestrate formula and split type two types.Window air conditioner is installed on the window, do not take the position in room, but noise is big, and efficiency ratio is low; Though the detachable air conditioner noise is little, take the certain space in room, and its hot unit that freezes must be contained in outdoorly, skyscraper is installed relatively difficulty.And these two kinds of air-conditioners all at single room design use, have a plurality of rooms will carry out heating and cooling as one family, then need to install many air-conditioners, very inconvenient.Chinese patent 96242244 discloses the technology that a kind of name is called " family central air-conditioning ", this technology is the transformation of existing central air-conditioning technology, adopts a wind cooling cold and hot water unit to make main frame, is with 3 to 10 indoor air-supply coil pipes, the supply hot and cold water carries out adjustment to the room.The advantage of this central air-conditioning is a noiselessness, and volume is little, is fit to family and uses.But its shortcoming is that incrusted deposit cleans difficulty, the heat exchange weak effect on the pipeline of brazing plate type heat exchanger when water quality is hard.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of soft or hard water quality can both use and the small central air conditioning device of good effect of heat exchange.
The utility model is achieved in that a kind of air-cooled small central air conditioning device, is made up of hot and cold water unit and indoor units two parts.The hot and cold water unit comprises compressor, four-way change-over valve, air-cooled condenser, heating power expansion valve, water tank and evaporation tube.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 the evaporation tube that places water tank with air-cooled condenser respectively, and air-cooled condenser links to each other by splash the expand another port of valve and evaporation tube of heating power again; Indoor units comprises blower fan and heat exchanger.Heat exchanger is communicated with water tank.
Heating wire is housed in the water tank.
The utility model compared with prior art has suitable hard water matter area and uses, good effect of heat exchange, the high and cheap advantage of efficiency ratio.
Fig. 1 is a structural representation of the present utility model.
Further describe the course of work of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, when the room need lower the temperature, the compressor (2) in the hot and cold water unit (1) was compressed into refrigeration working medium the gas of HTHP.These gases are cooled to liquid in four-way change-over valve (3) enters air-cooled condenser (11), pass through heating power expansion valve (4) again and enter in the evaporation tube (6), and the evaporation heat absorption turns cold the water in the water tank (5).Cold water is drawn in the heat exchanger (9) in the indoor units (8), starts blower fan (10), and cold wind blows into the room from heat exchanger (9).Chilled water after the intensification is got back to water tank (5) lining through heat exchanger (9) again.And the gaseous state refrigeration working medium of evaporation heat absorption enters compressor (2) through four-way change-over valve (3) in evaporation tube (6).Circularly cooling and so forth.
When the room need heat up, the heat of the refrigeration working medium of low-temp low-pressure absorption chamber outer air in air-cooled condenser (11) became the gas working medium of low pressure, was sucked the gas working medium that is compressed into HTHP by compressor (2) by four-way change-over valve (3).The gas working medium of HTHP enters in the evaporation tube (6) by four-way change-over valve (3) again, makes the water heating in the water tank (5).And the heating wire (7) that is contained in the water tank (5) is switched on, and the water in the water tank (5) is further heated up.Hot water carries out cold and hot exchange through indoor units (8), sends heating installation.Water after the cooling is got back to again in the water tank (5).And get back to air-cooled condenser (11) after the step-down of the process of the liquid working substance in the evaporation tube (6) heating power expansion valve (4), carry out a new round and heat circulation.
A hot and cold water unit of the present utility model (1) can be with 3 to 10 indoor units (8), and each indoor units (8) can open separately, stop to carry heating installation or cold air for the room.When a building has a lot of room, can adopt the form of " dragging many " more, be installed in parallel many hot and cold water units (1), needs of regulating according to room temperature and start entirely or part starts these hot and cold water units (1).
Because evaporation tube (6) is installed in the water tank (5), be easy to the incrustation scale that is deposited on the evaporation tube (6) is removed, so the utility model also is fit to use in the harder area of water quality.
Claims (2)
1. an air-cooled small central air conditioning device is made up of hot and cold water unit and indoor units two parts; The hot and cold water unit comprises compressor, four-way change-over valve, air-cooled condenser, heating power valve and the evaporation tube of expanding of splashing, the suction tracheae of compressor all is connected with the four-way scavenging air valve, two other port of four-way scavenging air valve links to each other with evaporation tube with air-cooled condenser respectively, and air-cooled condenser links to each other with evaporation tube by the splash valve that expands of heating power again; Indoor units comprises blower fan and heat exchanger; It is characterized in that the hot and cold water unit also is provided with water tank, evaporation tube places water tank, and heat exchanger is communicated with water tank.
2. air-cooled small central air conditioning device according to claim 1 is characterized in that being equipped with in the water tank heating wire.
