The air-cooled heat pump household air-conditioning system is based on a small air-cooled heat pump, providing hot and cold water as a cold and heat source for the air-conditioning system. The unit has a built-in water pump and an expansion water tank, and the indoor is a fan-coil water system, which is compact and simple.
According to the current economic level and the actual situation of residential air-conditioning, through the previous analysis, the factors of the simultaneous use of the room are taken into account when calculating the value of the air-conditioning load, so as to determine the selection of the host. This treatment is more in line with the actual situation, which can reduce the cost of the air conditioning system by about 20%, which is conducive to saving operating costs. The fan coils in the room are calculated according to the actual load of the room, so that the sum of the fan coil capacity of the indoors is greater than the cooling capacity of the air-cooled heat pump units. If the system is not designed, it will result in insufficient water supply to the fan coil that is running, and the output will not meet the design requirements. The dehumidification capacity will be reduced or even lost in summer, while the other part of the system will flow through the unoperated fan coil. To the role.
There are two ways to solve this problem: First, the water system is designed as a variable flow water system. An electric two-way valve is arranged on each fan coil, and a bypass pipe and a differential pressure controller with a charging valve are arranged on the main supply and return pipe. This can reasonably distribute the amount of water according to the load, but because of the use of some control equipment, the system cost is increased, and the house with good conditions can use this method. Second, make some changes in the water system pipeline, so that the system's water supply first flows through the fan coils of the living room and dining room, then distributes to the fan coils of each bedroom, and the fan coils of each bedroom are matched. 20%. After the system is adjusted in this way, when the two fan coils are running and the bedroom fan coils are stopped, the air conditioning requirements in the hall can be met; when the bedroom fan coils are running and the fan coils in the hall are stopped, the water supply flows through the hall. The temperature rise caused by the inner fan coil is very small, so it is considered that it can meet the air conditioning requirements of the bedroom: when one hall and a few bedroom fan coils are running, the temperature of the water supply flowing through the fan coil in the hall rises by about 2 to 2.5 OC. The fan coil of the bedroom is 20% larger, which can also meet the air conditioning requirements, but the dehumidification capacity has decreased.
It can be seen from the above analysis that the water system has been treated in this way, but the effect is not as good as the previous one, but it can basically meet the air conditioning requirements under different operating conditions, and the system is simple and reliable, and the investment is less. This option can be considered when the owner is more sensitive to the cost of the air conditioning system.
