Filter, refrigerating system, indoor unit and air conditioner

Abstract

The invention provides a filter for filtering a refrigerant in a refrigerating system. The filter comprises at least two filter channels, wherein the at least two filter channels are integrally arranged in parallel; the at least two filter channels are provided with filter cavities; and filter screen devices are arranged in the filter cavities. An integrated filter in which multiple filter channels are connected in parallel is designed, so that multi-time filter needs, on the refrigerant, in the refrigerating system are met, space occupation problem of multiple filter device bodies is solved,once assembly and once noise-reduction treatment only need to perform on an integrated structure, space occupation is reduced, a small-sized design of the indoor unit of the air conditioner is facilitated, number of parts is reduced, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a filter, a refrigeration system, an outdoor unit and an air conditioner. Background technique [0002] The compressor, the core component of the refrigeration system of the room air conditioner, often fails in use, among which the stuck and locked rotor account for more than 40%. . Capillary tubes are the most important throttling components of air conditioners. Their internal apertures are 0.3 to 1.9 mm, and there is a hidden danger of being blocked by impurities in the refrigeration system. Therefore, the design of the filter in the refrigeration system is very important. [0003] There are generally four filters in the refrigeration system, namely: exhaust filter, return air filter, filter before throttling part, and filter after throttling part. In order to reduce the volume, the return air filter and exhaust filter can also be omitted. Air filter, only th...

Problems solved by technology

[0004] At present, with the continuous development of market demand and technology, the requirements of customers are getting higher and higher, and there are also certain requirements for the appearance and size of the outdoor unit. The size of the shell is getting smaller and smaller, and the use of two or more filters takes up a lot of space. Housing cannot reserve suitable space
