Abstract

The invention belongs to the technical field of heat pump unit testing, and in particular relates to a testing device for a chiller unit with heat recovery function. The present invention includes an evaporator-side circulation pipeline connected to the evaporator, a condenser-side circulation pipeline connected to the condenser, and the evaporator-side circulation pipeline and the condenser-side circulation pipeline pass through the first water-water circulation pipe The device also includes a heat recovery side circulation pipeline connected to the heat recovery unit. The heat recovery side circulation pipeline forms a closed cycle with the heat recovery unit. The device also includes a second water-mixed circulation pipeline. The circulation pipeline on the side of the heat recovery unit communicates with the external cold source, or the circulation pipeline on the evaporator side, or the circulation pipeline on the condenser side through the second water-mixed circulation pipeline. The advantage of the invention is that: the invention provides a separate pipeline and equipment for the heat recovery device, which can satisfy the simulation experiment of the water chiller with heat recovery function, and can carry out the simulation experiment of partial heat recovery and full heat recovery.

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...
