Heat pump performance claims now independently corroborated

With that in mind, Zhuhai Gree Electric Appliance Co. came to UL to have the performance of its ultra-low temperature heat pump air-conditioning models GMV-36WL/B-T(U) and GMV-48WL/B-T(U) independently verified by UL.

UL has Verified the following claims for these two Gree products:

• The pump demonstrates 100% heating capacity at an outdoor temperature of -20 ⁰C (-4 ⁰F)
• The pump demonstrates 80% heating capacity at an outdoor temperature of -30 ⁰C (-22 ⁰F)
• The pump demonstrates stable operation at an outdoor temperature of -35 ⁰C (-31 ⁰F)

UL's Verified Mark demonstrates that UL has Verified a specific marketing claim of these products through independent, repeatable, science-based assessments.  UL's Verification provides objective credibility to the accuracy of the marketing claims that manufacturers use to differentiate their products from the competition, and enables easier purchasing decision making.  For Gree's projects, UL performed a total of four sets of sample comparison tests: heating under the standard conditions, heating under outdoor conditions of -20 ⁰C, heating under outdoor conditions of -30 ⁰C, and heating under outdoor conditions of heating -35 ⁰C respectively. The test results showed that the heating capacity of Gree's two heat pumps performed as claimed under the different temperature conditions.

As a leading enterprise in China's air-conditioning industry, Gree has been focused on the development of low temperature heating technology in the HVAC industry. "Through the UL verification, we and our customers can have full confidence in our product's performance in the most challenging of heating environments," said Mr. Ouyang Jun, the Vice General Manager of Gree Overseas Sales Company.
