Abstract

The invention, which belongs to the technical field of heat pump unit testing, particularly relates to a test device for testing a water chilling unit with the heat recovery function. The test devicecomprises an evaporator-side circulation loop connected to an evaporator and a condenser-side circulation loop connected to a condenser. The evaporator-side circulation loop and the condenser-side circulation loop are communicated by a first water-mixing circulation loop. In addition, the device also includes a heat-recovery-unit-side circulation loop connected to a heat recovery unit; and the heat-recovery-unit-side circulation loop and the heat recovery unit form a closed cycle. The device also includes a second water-mixing circulation loop; and the heat-recovery-unit-side circulation loopis communicated with an external cold source, the e evaporator-side circulation loop, or the condenser-side circulation loop through the second water-mixing circulation loop. The test device has the advantages that: the separate loop and equipment are provided for the heat recovery unit; the simulation experiment of the water chilling unit with the heat recovery function is realized; and the simulation experiment of partial heat recovery and full heat recovery can be carried out.

Description

technical field [0001] The invention relates to the technical field of heat pump unit testing, in particular to a testing device for testing a chiller unit with heat recovery function. Background technique [0002] 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 equipment operating costs and noise, shorten the running time of cooling towers and cooling pumps, and heat recovery can not only reduce operating costs but also reduce environmental pollution, achieving the goal of energy saving and emission reduction. Exist...
