Heat pump performance testing system

Abstract

The invention provides a heat pump performance testing system, which relates to the technical field of heat pump performance testing. The testing system comprises a water chilling unit system, a balance water tank loop and a standard water tank loop, wherein the standard water tank loop is connected between the water chilling unit system and a tested unit; the balance water tank loop comprises a balance water tank, and one part of the loop formed by the balance water tank and tested unit is also provided with a water circulating pump, a flow meter and a proportional three-way valve; the standard water tank loop is connected between the water chilling unit system and the tested unit; the standard water tank loop comprises a standard water tank; one connection point of the standard water tank is arranged between the water circulating pump and an electric heater; and the other connection point of the standard water tank is arranged between the flow meter and the proportional three-way valve. Through organic combination of different water path testing systems, the testing system of the invention meets different using requirements in the case of heat pump water heater testing and air conditioning water chiller testing, former repeated resource input can be effectively avoided, and the production cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of heat pump performance testing, in particular to a heat pump performance testing system. Background technique [0002] The test systems of the traditional heat pump waterway test are generally independent of each other, that is, each type of HVAC equipment has a corresponding test system with its configuration, and each test system is separated from each other without any relationship. Moreover, the test system is complicated, and a large amount of electric auxiliary heating is used to adjust the temperature. [0003] The existing test system consumes a lot of energy, takes a long time to achieve a balanced effect, and requires repeated investment of resources. Specifically, some test systems have overlapping structures, and sometimes two or more test systems need to be combined according to needs. Complete the work, which is time-consuming and troublesome, and the investment in the test system is relativ...

[0002] The test systems of traditional heat pump waterway tests are generally independent of each other, that is, each type of HVAC equipment has a corresponding test system with its configuration, and each test system is separated from each other without any relationship

Moreover, the test system is complex, and a large number of electric auxiliary heating are used to adjust the temperature

[0003] The existing test system consumes a lot of energy, takes a long time to achieve a balanced effect, and requires repeated investment of resources. Specifically, some test systems have overlapping structures, and sometimes two or more test systems need to be combined according to needs. Get the job done, which is time-consuming, cumbersome, and expensive to test the system
