LTLHM Series Screw Compressor Ground Source Heat Pump for Heating Cooling Domestic Hot Water

Wide range of application:

Acting as multi-function unit such as cooling, heating, sanitary hot water separately or simultaneously. Wide

application as hotel, apartment, villa, factory, shopping center, office building, school, etc.

Green Products:

Adopting non-pollution and environment-friendly refrigerant; Great environmental and economic benefit; no boiler or cooling tower; less space, less CO² and less initial investment; Run-time without waste discharge, when heating replaces the boiler.

Stable and Reliable Operation:

1)Semi-hermetic screw compressor. Each compressor is equipped with a crankcase heater and a thermal overload cut-out; The screw compressor is also complete with a built-in electronic protection with temperature sensor located directly in the motor winding and on the discharge line.

2)The refrigerant circuit is equipped with sight glass, filter drier, high and low pressure gauges, solenoid valve, direct expansion valve, high and low pressure switch.

3)Shell and tube dry expansion type condenser, factory insulated with flexible close cell material. Shell and tube type evaporator, factory insulated with flexible close cell material.

4)The electric panel consists of compressor breaker, compressor contactor, phase sequence relay, control circuit breaker, microprocessor control with function display.

5)LCD display, touch screen control panel as standard.

6)Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.

7)For the units with semi-hermetic screw compressor, an infinitely variable capacity control system that is capable of exactly matching the demand requirement of the system is to be supplied. This system is to provide precise and stable control of supplywater temperature over the complete range of operating conditions.

High Efficiency and Energy Saving:

COP 4.5-5.5, low running cost, compare with other heating system can save 1/2-1/3.

Q: Are Heat Pumps reliable?

A:Yes. Heat pumps are extremely reliable. They use the same process as a home fridge or freezer and have the same level of dependability and life expectancy.

Q: What is the average life-span of a Heat Pump?

 A:It can vary, depending on how much the system is used and how regularly it is checked or serviced. Generally, the average life-span of units built in the 1970s and 1980s is about 15 years, but individual units may vary and last much longer depending on use and how well they are maintained. Newer units are expected to last even longer.

Q:Why are Heat Pumps better than other forms of heating?

A:Heat pumps offer many benefits over other forms of heating. Firstly they are much cheaper to run giving up to 4 times more heat than you pay for, they can be used all year round for heating and cooling. They don't pollute our atmosphere because they use ozone friendly refrigerants.
