Abstract

The invention belongs to the technical field of heat pump unit testing, and particularly relates to an improved water chilling unit testing device with a heat recovery function. The testing device comprises an evaporator side circulating pipeline connected with an evaporator, and a condenser side circulating pipeline connected with a condenser, the evaporator side circulating pipeline is communicated with the condenser side circulating pipeline through a first water mixing circulating pipeline; the device further comprises a heat recoverer side circulation pipeline connected with a heat recoverer. The heat recoverer side circulation pipeline and a heat recoverer form closed circulation. The device further includes a second water mixing circulating pipeline; the heat recoverer side circulation pipeline is communicated with an external cold source, the evaporator side circulation pipeline or the condenser side circulation pipeline through the second water mixing circulation pipeline. Thetesting device has the advantages that independent pipelines and equipment are arranged for the heat recoverer, the simulation experiment of the water chilling unit with the heat recovery function can be met, and the simulation experiment of partial heat recovery and total heat recovery can be carried out.

Description

[0001] The present invention is a divisional application, the filing date of the original application is September 27, 2018, the application number is 201811129878.X, and the name is a test device for testing chillers with heat recovery function. technical field [0002] The invention relates to the technical field of heat pump unit testing, in particular to an improved testing device for testing a chiller unit with heat recovery function. Background technique [0003] The heat released by the cooling water of the chiller is usually discharged to the surrounding environment by the cooling tower, which is a huge waste for places that need heat, such as hotels, factories, hospitals, etc., and at the same time brings a certain amount of waste heat pollution to the surrounding environment . The heat recovery technology is to recover and reuse a large amount of waste heat discharged to the outside during the operation of the chiller in a certain way. It can save energy, reduce e...
