What is Climate control evi heat pump supplier and Why Do We Use Them?

EVI stands for Enhanced Vapor Injection, which is a technology utilized in our low-temperature heat pumps to deliver higher performance in cold climates. EVI allows a 20% increase in refrigerant flow into the evaporator at a lower entry temperature. It incorporates a 3rd smaller internal plate heat exchanger referred to as an "Economizer" in the refrigeration cycle. Some of the refrigerant vapor on the condenser combines with the cooler gas on the expansion side of the evaporator through a bypass valve. This combination leads to the transfer of heat energy, which increases the gas temperature further and is then injected into the head of the scroll compressor through a separate vapor injection port at mid-range pressure. With EVI heat pump technology, the maximum flow temperature limitation of other cold climate heat exchangers is overcome, and more heat is delivered, resulting in a better COP at much lower temperatures. The performance efficiency is increased by 20-30%.

With competitive price and timely delivery, guangteng sincerely hope to be your supplier and partner.

To start, our DC Inverter Heat Pump uses the industry&#;s best compressor &#; a variable speed DC Panasonic EVI compressor. This DC motor runs at the exact speed it needs for the optimal efficiency. Most heat pumps use a single or dual speed compressor. This means it is ether off or on.

This is very important, as the compressor consumes the bulk of the energy requirement for a heat pump. By reducing the energy of the compressor the COP (co-efficiency of performance) is greatly increased. The Brushless DC fan motor and PFC control the running capacity and require no start up capacitor. By not requiring constant starting and stopping involved with conventional motors, our motor both reduces required input energy and reduces &#;wear & tear&#; on the compressor.
