Coolant distributor for altering the number of indoor set driven by outdoor set

Abstract

The invention relates to an air conditioner, in particular to a refrigerant distributor that changes the capacity and quantity of indoor units driven by an outdoor unit, which comprises a casing forming the appearance; an installation stand at four corners behind the casing; a control box in front of the casing; a control board in the control box; thick and thin conduit joints installed at the upper side of the casing and for connecting the refrigerant flow-in and flow-out conduit of the outdoor unit; thick and thin conduit joints installed on the step surface at lower side of the casing and for connecting the refrigerant flow-in and flow-out conduits of a plurality of indoor units; a thick and a thin distribution pipe that are arranged in the casing, for which, one main pipe is divided into a plurality of branch pipes, and the two main pipes are connected with the thick and thin conduit joints installed at the upper side of the casing, the branch pipes are connected with the thick and thin conduit joints installed on the step surface at lower side of the casing, and an expansion valve is installed in the thin distribution pipe. The invention is characterized in that, the thick and thin conduit joints installed on the step surface at lower side of the casing are additionally designed with Y-like refrigerant T joints for connecting them in parallel.

Description

Technical field [0001] The invention relates to air conditioning technology, in particular to a refrigerant distributor for changing the capacity and number of outdoor units towing indoor units Background technique [0002] Generally speaking, an air conditioner is a device that regulates indoor air and maintains the indoor environment in an optimal state. The principle of regulation is: using an electric fan to make the air conditioner suck indoor air, make it exchange heat with the refrigerant compressed in the refrigerant pipe and the heat exchanger by the compressor, and then discharge it back into the room. Repeat the above process for indoor air Cooling or heating. [0003] Recently, in addition to cooling and heating, air conditioners have added an air purification function that sucks in turbid indoor air and filters it and then discharges clean air into the room, and a dehumidification function that converts moist air into dry air and then discharges it back into the room...

Problems solved by technology

[0020] However, the existing one-to-multi-type air conditioner can only tow multiple small-capacity indoor units when the power or capacity of the outdoor unit allows it. For example, an 8HP air-conditioner outdoor unit can tow four indoor units of two horsepower, referred to as One-to-four air conditioners use one-to-four refrigerant distributors in the refrigerant connecting pipes between the outdoor unit and the indoor unit, and also produce one-to-three air conditioners according to the capacity of the air-conditioning outdoor unit, indoor unit and user needs. They are collectively referred to as one-to-one Tow multi-type air conditioner, in order to distribute the refrigerant flowing out of its outdoor unit to each of its indoor units, one to four, one to three and other one tow multi-refrigerant distributors should be installed in the connection of the refrigerant pipes of the outdoor and indoor units. The use of one-to-many refrigerant distributors limits the capacity and number of indoor units towed by one outdoor unit and cannot be changed flexibly. For example, an 8HP air-conditioning outdoor For a four-horsepower indoor unit, you have to buy another 8HP and two refrigerant distributors for four-horsepower indoor units to install in the outdoor and indoor unit refrigerant connecting pipes to distribute refrigerant, so the factory must process and produce various refrigerants with one drag and more The user must purchase a refrigerant distributor that matches various one-drag multi-type air conditioners. If he wants to change the capacity of the towed indoor unit, he must purchase another matching refrigerant distributor, which increases the user's cost. economic burden
