Abstract
The utility model discloses an indoor-type radiation central air-conditioning system with constant temperature of supplied water. The system comprises a circulating loop at a client side and a circulating loop at a working end, wherein the circulating loop at the working end comprises a water tank, a fan and a unit system; and the unit system comprises a frequency converter which is connected with a water pump of the unit system, and is used for changing frequency according to the discharged water temperature of the unit system and then adjusting the rotation speed of a compressor through the water pump to realize constant discharged water temperature. The utility model has the following advantages: 1) the fluctuation of temperature and humidity of indoor air state point is reduced, which is favorable for the improvement of comfort of human body; 2) since the water temperature of a radiation tail end is constant, the phenomenon that users feel uncomfortable caused by fluctuation of the temperature of supplied water cannot occur; and 3) for the automatic control system of tail end equipment, the service life of an actuator is greatly prolonged and the reliability of the system is improved.
Description
Technical field
The utility model belongs to the air-conditioning system technical field, and particularly a kind of needs that are used for dwelling house guarantee the air-conditioning system of system's effluent temperature constancy.
Background technology
Along with expanding economy, people are more and more higher for the requirement of housing quality, and residential central air-has also obtained using comparatively widely.
The mode that the existing central air conditioner system that is used for the family formula is regulated refrigerating capacity mainly realizes control by the start and stop of heat pump or cold machine, and the major defect of this method is that bigger fluctuation can take place the supply water temperature of hot and cold water in heat pump or the cold machine shutdown process.Indoor temperature is had certain influence, and one is opened one and is caused room temperature sometimes hot and sometimes cold easily in the middle of stopping; The automatic control of central air-conditioning realizes having big difficulty in addition.
Convertible frequency air-conditioner has had comparatively mature technique in the normal domestic use air-conditioning, but does not still use this technology in the formula radiant type central air conditioner system of family.
The utility model content
Technical problem to be solved in the utility model provides the radiation central air conditioner system of the constant supply water temperature of a kind of family formula, can constant hot and cold water leaving water temperature.
For solving the problems of the technologies described above, the utility model provides the radiation central air conditioner system of the constant supply water temperature of a kind of family formula, comprise user side closed circuit and working end closed circuit, described working end closed circuit is made of water tank, blower fan and machine set system, it is characterized in that, described machine set system comprises a frequency converter, this frequency converter links to each other with the water pump of described machine set system, be used for changing frequency, and then compressor rotary speed regulated the constant leaving water temperature of realization by water pump according to the leaving water temperature of described machine set system.
In system's running, heat pump or handpiece Water Chilling Units load terminal according to radiation and new blower fan group is realized the constant of unit leaving water temperature by regulating unit inner compressor rotating speed.The utlity model has following advantage: the first, the fluctuation of room air state point humiture reduces, and helps the raising of human body comfort; The second, terminal for radiation because water temperature is constant, regulate and automatic control on more or less freelyly reach designing requirement, each room temperature differential in the time of can not causing debugging again owing to the fluctuation of supply water temperature is bigger, makes the people produce discomfort; The 3rd, for the robot control system(RCS) of end-equipment, the robot control system(RCS) regulating frequency reduced after water temperature was constant, and the change bypass amount that no longer needs not stop guarantees relative stationary temperature, and actuator can improve service life greatly, increases the reliability of system.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is that a kind of mixed water valve of the utility model is regulated the system embodiment schematic diagram of radiation terminal temperature;
Fig. 2 is that a kind of plate type heat exchanger of the utility model is regulated the system embodiment schematic diagram of radiation temperature;
Fig. 3 is a systematic schematic diagram in the utility model unit.
The specific embodiment
As depicted in figs. 1 and 2, this central air conditioner system comprises user side closed circuit 1 and working end closed circuit 2, and working end closed circuit 2 is made of water tank 21, blower fan 22 and machine set system 23.User side closed circuit 1 comprises radiant panel, and this radiant panel can adopt capillary, ceiling or floor pipe laying.Can regulate the temperature (see figure 1) by mixing water valve between working end closed circuit 2 and the user side closed circuit 1.Can regulate the temperature (see figure 2) by plate type heat exchanger between working end closed circuit 2 and the user side closed circuit 1.
Further, as shown in Figure 3, machine set system 23 comprises heat pump or freezing machine 231, water pump 232, evaporimeter 233.Machine set system 23 also comprises a frequency converter 234, this frequency converter 234 links to each other with the water pump 232 of machine set system 23, the delivery port of heat pump or water chilling unit system 23 can be adorned a temperature sensor, and the output of this temperature sensor is connected with the input of frequency converter 234, can detect coolant-temperature gage.Frequency converter 234 is used for changing frequency according to the leaving water temperature of machine set system 23, and then regulates the constant leaving water temperature of realization by 232 pairs of compressor rotary speeds of water pump.
Under the prerequisite that guarantees effluent temperature constancy, again by the self-con-tained unit in the air-conditioning system, realize the constant of terminal supply water temperature, this self-con-tained unit is mature technique in the existing central air-conditioning, promptly can monitor the action control three-way control valve or the mixed water valve of the temperature and pressure control actuator on each branch road of threeway by sensor, by the control bypass flow, the water temperature behind the change control device, and keep this water temperature can reach a less relatively fluctuation range.
