Daikin air conditioner VRV U series, a system equipment is broken, is it air conditioning and floor

Daikin air conditioners, with underfloor heating or hot water systems, are actually one external unit with multiple internal units.

So if the equipment of the outdoor unit fails, the air conditioner and floor heating will not work. For example: external fan failure, compressor failure, each temperature sensor failure, external computer board failure, etc.

If it is a single internal machine failure, the other can operate normally under the premise that the fault does not trigger pressure protection. For example, the failure of the internal fan of the air conditioner during heating does not affect the use of floor heating.

Daikin has been applying air source heat pump technology to air conditioning and heating for more than 50 years. After years of hard work, Daikin has combined mature air source heat pump technology with DC frequency conversion technology and thermal technology to break through the problems of refrigerant control and achieve a multi-functional VRV set of equipment to realize the functions of household air conditioning, floor heating and domestic hot water.

Introduction to the functional VRV system.

Daikin Multi-Purpose VRV

It is a system that integrates the three major equipment of household air conditioning, air source heat pump floor heating and air source heat pump water heater to solve the cooling in summer, heating in winter and hot water demand throughout the year in the most energy-saving and reasonable way.

Daikin Multi-Purpose VRV

It has the following characteristics: 1. Multi-functional all-in-one machine.

The multi-functional VRV can realize the functions of household air conditioner, air source heat pump floor heating, and air source heat pump water heater, and is a new type of VRV system that integrates the three major equipment into one, with more powerful functions.

2. After the integration of equipment is realized, more home space can be released, and the façade is more beautiful. Not only that, the whole system only needs one external unit, which can greatly reduce the number of outdoor units and reduce the space for equipment placement. At the same time, the façade of the building is more beautiful and more upscale.

3. Comfortable cooling and heating experience. From the comfort of the human body, the form of floor heating, which is closest to one of the ideal heating methods, is introduced into the VRV system. In general, the use of air conditioning in summer and floor heating in winter has been realized to obtain the most comfortable cooling and heating experience.

Because of the air conditioner, the cold air will automatically sink down from the roof, and the cold air will be concentrated in the area where people are moving; Floor heating heat, heat directly from the feet, warm the most need for heat, is a more comfortable way to match cold and warm.

4. Household air conditioner, hidden in the ceiling; Underfloor heating, water pipes are laid only under the floor, no exposed equipment. With different decoration styles, it realizes the beauty of "Tibet" and reflects the noble home taste.

5. Thermal technology can effectively utilize the waste heat of air conditioning. Under the powerful function of equipment integration, advanced thermal technology is used to effectively use the waste heat discharged by the outdoor unit of the air conditioner to heat domestic hot water, which is energy-saving and efficient, and effectively alleviates the urban heat island effect.

Don't buy this Dajin floor heating one, just used today, turn on the floor heating, the outdoor unit will defrost the refrigerant will flow, will drive all the indoor hosts to make a loud noise, will be woken up in the middle of the night, I am considered to be pitted.

It depends on what system equipment is broken.

Daikin air conditioner vrv report u4 how to solve hello dear, daikin air conditioner fault **u4 is subdivided into two kinds of faults: 1, u4-01: internal and external transmission abnormality 2, u4-03:

In view of the above two situations, Daikin air conditioner after-sales maintenance engineer solutions: 1. Check whether the transmission wiring of the indoor unit-outdoor unit and the outdoor unit-outdoor unit is normal. 2. If the P board of the indoor unit or the P board of the outdoor unit has been replaced, the transmission wiring of the indoor unit to the outdoor unit and the outdoor unit to the outdoor unit has been modified, press and hold the RESET button for more than 5 seconds.

3. Check if HAP is flashing? If it does not blink, check whether the power supply voltage and the fuse on the P board are blown out. 4. If the H2P flashes or does not go out after 12 minutes, check whether the transmission wiring of the indoor unit and the outdoor unit and the outdoor unit is normal.

5. After removing the outdoor unit and the connecting wires between the outdoor units, whether the single system is in the main hall.

Summary. Hello dear, the solution of Daikin air conditioner vrv report u4 is as follows:1

You can turn off the indoor and outdoor power, and then turn it on and restart the air conditioner. 2.Check whether the transmission wiring of the indoor unit-outdoor unit and the outdoor unit-outdoor unit is normal, and try to plug them in.

3.In addition, it should be noted that the indoor unit and outdoor unit in the same system must be powered at the same time, otherwise the U4 fault will also be reported. 4.

If the power supply is re-closed and the U4 is reported, it may be that the plate is burned or the signal line is disconnected, and it needs to be repaired. <>

How to solve the UF of <> Daikin VRV air conditioner: 1. The refrigerant is not sensitive enough, it is recommended to contact professionals to detect leaks and add refrigerant. 2. The one-way valve leaks, resulting in the temperature of the outdoor heat exchanger rising under the high and low pressure difference of the refrigeration system, and the heat obtained from the outside world is reduced, resulting in insufficient heat dissipation from rough excavation.

Repair of the check valve is sufficient.
