Abstract

The invention provides an indoor and outdoor unit connection pipe for a splitting type heat pump and refrigeration equipment. The connection pipe is a full-copper connection pipe, wherein an inner connection section connected with an indoor unit and an outer connection section connected with an outdoor unit are arranged at the two ends of the connection pipe are respectively; the full-copper connection pipe comprises a middle section; one end of the middle section is fixedly connected with the inner connection section; the other end of the middle section is fixedly connected with the outer connection section; the wall thickness of the middle section is smaller than the wall thicknesses of the inner connection section and the outer connection section. The invention provides the indoor and outdoor unit connection pipe for the splitting type heat pump and the refrigeration equipment, which can effectively reduce the cost under the precondition of ensuring the utilization performance.

Description

technical field [0001] The invention relates to a split heat pump and refrigeration equipment, in particular to a connecting pipe for indoor and outdoor units. Background technique [0002] For split-type heat pumps and refrigeration equipment, such as split-type air conditioners, connecting pipes are needed to connect the indoor unit and outdoor unit. Commonly used connecting pipes are all-copper connecting pipes, copper-aluminum connecting pipes or all-aluminum connecting pipes. [0003] The all-copper connecting pipe is a connecting pipe for the transmission of refrigerant between the indoor and outdoor units of the air conditioner. Generally, two pipes are used together. One pipe transmits low-temperature and low-pressure gaseous refrigerant, and the other pipe transmits high-temperature and high-pressure liquid refrigerant. At present, copper prices are high, and the price of air-conditioning connecting pipes is relatively high, so many manufacturers use two methods to ...
