Introduction

Total heat solution - Heating, cooling, domestic hot

water in one system

Thermal    is    an    integrated   system   that   heats   and    cools    space,   as    well   as    produces    domestic    hot   water. It   o ff ers    total   heat solution   all   year   round.   This   system   can   complete   instead   of   the   tradition   gas   or   other   fuel   boilers,   it   also   can   work together with them.
Renewable energy source R410A, low CO2 emission, environmentally  friendly DC inverter technology, high energy efficiency Sufficient heating capacity at low ambient temperature (even at-20°C) Provide space heating, cooling and domestic hot water, total heat solution Compatible with other heat source such as solar energy and boiler

How air source heat pump works

A   heat   pump   is   an   energy   efficient   system   that   absorbs   heat   from   the   ambient   air   for   heating   and   hot   water.   By using   the   ambient   air   and   transferring   this   heat   into   the   house   through   a   hydronic   system,   such   as   floor   heating, fan coil units and radiators
Compressor Expansion Valve
Condenser
Heat Distribution
Heat Source
Evaporator
Stage One The   heat   transfer   medium   (the   refrigerant)   is   colder   than   the   heat   source   (the   outside   air).   As   the outside   air   passes   across   the   fi rst   heat   exchanger   (the   evaporator)   the   liquid   refrigerant   absorbs the heat and evaporates .
1
Stage Two The vapor passes to the compressor and is compressed. When compressed the pressure  is increased and the temperature of the vapor rises, effectively concentrating the heat.
2
Stage Three The   hot   vapor   passes   to   the   second   heat   exchanger   (the   condenser)   where   the   heat   is   released to   the   water   and   the   vapor   condenses   back   into   a   liquid.   The   water   heated   in   by   the   Thermal system is circuit to the indoors for central heating and domestic hot water heating.
3
Stage Four The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature, ready to start the next circuit.

Floor heating
Mono outdoor unit Mono outdoor unit absorbs heat from the outside air and transfers it to the water in the hydronic modular, through water to supply heat to indoor side. Domestic water tank (field supplied) Domestic   water   tank   is   used   to   supply   sanitary   hot   water.   The   hot   water   from   the   Mono   unit   release   heat   to   water   in   the   tank   through   the inner coil, and cold water in the tank is heated. Usually there is an addition electric heater in the domestic water tank. User interface User interface is connecting to the Mono unit through signal wire; it mainly uses for ON/OFF the unit, mode setting, temperature adjusting and timer setting.

Typical Applications   
Example: Application 2: Thermal Mono for space heating and domestic hot water Room   thermostat   is   not   connected   to   the   Mono   unit   but   to   motorized   valve.   Each   room’s   temperature   is   regulated   by   the   motorized   valve on   every   water   circuit.   Sanitary   hot   water   is   delivered   by   the   domestic   hot   water   tank   connected   to   the   Mono   unit.   In   this   situation,   bypass valve is necessary.
