Description

Heat Exchangers and Air Conditioners

technical field

The utility model relates to the technical field of household appliances, in particular to a heat exchanger and an air conditioner.

Background technique

In colder climates, four-pipe terminal heat exchangers are usually used in air conditioners. That is, the heat exchanger is divided into two water systems, the refrigeration system and the heating system. Among them, the refrigeration system is used to connect the module machine for cooling in summer, and the heating system is used to connect to the boiler water for heating in winter. The two systems do not share the heat exchanger pipeline. When the four-pipe terminal heat exchanger with this structure is adopted, both the refrigeration system and the heating system use independent inlet and outlet water collection valve groups, namely, cold water inlet water collection valve group, cold water outlet water collection valve group, hot water inlet valve group, and hot water inlet valve group. There are four sets of water collecting valve assemblies in total for the water collecting valve group and the hot water outlet water collecting valve group. Among them, the cold water inlet valve group and the cold water outlet valve group are connected to the modular machine and the terminal heat exchanger refrigeration system, and the hot water inlet valve group and the hot water outlet valve group are connected to the boiler and the terminal heat exchanger heating system. However, in the existing heat exchanger, when the refrigeration system is working, the heating system in the heat exchanger will be idle; when the heating system is working, part of the refrigeration system in the heat exchanger will be idle.

In addition, when the refrigeration system and heating system of the heat exchanger both use independent "inlet and outlet water collection valve groups", the installation accuracy of the heat exchanger is high, and some models of terminal air conditioners cannot be installed with four sets due to structural limitations. The water collection valve group makes it impossible to make a four-pipe model.

The water inlet pipe of the refrigeration device is connected, and the second outlet is connected with the water inlet pipe of the heating device.

The heat exchanger proposed in this embodiment achieves the purpose of sharing the heat exchanger of the cooling device and the heating device by installing the water outlet valve group and the water inlet valve group on the heat exchanger. For some indoor units that are inconvenient to install For the air conditioner with relatively small space for the heat exchanger, the installation of this heat exchanger can achieve the function of using a two-pipe heat exchanger to achieve a four-pipe heat exchanger, which meets the structural requirements of the end indoor unit in a small space, and at the same time It can also save the cost of a set of heat exchangers.

When there is confusion, the circulating water in the heating device will flow into the cooling device, and the circulating water in the cooling device will flow into the heating device. The one-way valve is one-way flow, so there is no problem of reverse flow. Therefore, the water in the heat exchanger will not enter the refrigeration device or heating device through the one-way valve, so there will be no leakage in the heating device.
