An air conditioner system including a sleeping enclosure defining a sleeping space into which conditioned air is adapted to be delivered from one end or side of the sleeping space in a manner which maximizes contact between conditioned air and a person or persons in the sleeping space, the sleeping space including an upper air pervious section; and a lower relatively air impervious section adapted to surround a bed in the sleeping space and configured to minimize passage of the conditioned air from the sleeping space through the pervious section or other leakage paths; and an air conditioner unit for generating a conditioned air flow, wherein the impervious section extends to a height above the sleeping surface of the bed at the end or side of the bed opposed to said end or side sufficient to contain the conditioned air as it moves towards and returns from the opposite end or side of the sleeping space, and wherein the impervious section extends to a sufficiently increased height above the sleeping surface at the opposite end or side to allow the direction of air flow to reverse towards said one end or side without substantial loss of conditioned air through the pervious section.

The disclosure provides a multi-function ductless enclosure apparatus. Its main purpose is to be used as a paint spray booth to capture excess paint, pass it through filters with the use of a fan and then exhaust the ensuing clean air out, back into the room air. This booth is foldable and light weight and can be moved to a different location in minutes. It can also be transformed to serve many other applications with the use of a few accessories thereby saving the end user from having to have several booths (saving counter space) and also saving him from having to spend a lot of money buying many booths for different applications.

A dehumidification system for removing water vapors from an air is disclosed. The system includes a dehumidification core defining an air channel and at least one vapor channel separated from the air channel by a membrane to facilitate a removal of moisture from the air flowing through the air channel and is selectively permeable to water and water vapor and impermeable to air. The dehumidification system further includes a water ejector having a throat portion fluidly coupled to the vapor channels and adapted to create a relatively lower pressure of water vapor within the vapor channels than in the air channel The water ejector also includes an outlet portion disposed downstream of the throat portion and configured to increase the pressure of water to facilitate a condensation of the water vapors received from the vapor channels.

A dehumidifying system includes an enclosure having at least one opening disposed at a first end and at least one opening disposed at a second end. A plurality of air paths that extend through the enclosure and are separated from one another by partitions along at least a portion of the enclosure. A dehumidifier evaporator is disposed within the enclosure and configured such that at least one of the air paths is disposed to flow through the dehumidifier evaporator. The dehumidifier evaporator includes a dehumidifying coil and a heat pipe assembly at least partially wrapping around the dehumidification coil.

Disclosed herein is a refrigeration cycle includes a first refrigerant circuit configured to cause a refrigerant ejected from a compressor to flow through a condenser, an ejector, a first evaporator, and a second evaporator and flow back to the compressor; a second refrigerant circuit configured to cause the refrigerant to bypass the first evaporator in the first refrigerant circuit; and a third refrigerant circuit branching at a junction provided at a downstream end of the condenser from at least one of the first refrigerant circuit and the second refrigerant circuit, and configured to cause the refrigerant to flow through an expansion device and a third evaporator and flow to the ejector. By such configuration, a coefficient of performance (COP) of a refrigeration cycle may be improved and an ejector may be used to improve energy efficiency.

A refrigeration cycle apparatus includes refrigerant circuits in which a high pressure shell compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger are connected; a mixed refrigerant containing 1,1,2-trifluoroethylene and a refrigerant other than 1,1,2-trifluorothylene and circulating through the refrigerant circuits; and a refrigerating machine oil enclosed in the refrigerant circuits and adjusted such that 1,1,2-trifluoroethylene will be more soluble therein than the other refrigerant is.

The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system. The HVAC system includes an air handling unit configured to transfer heat between a refrigerant and an airflow, a first heat exchanger configured to receive the refrigerant from the air handling unit and transfer heat between the refrigerant and a first working fluid, a cooling bank including a vessel and a coil disposed in the vessel, wherein the coil is configured receive the first working fluid from the first heat exchanger and configured to transfer heat between the working fluid and a second working fluid within the vessel, and a second heat exchanger configured to receive the second working fluid and to transfer heat between the second working fluid and the airflow, wherein the second heat exchanger is disposed upstream of the air handling unit with respect to a flow path of the airflow.

An ice-maker in a refrigerator is capable of producing ice pieces through directly cooling by a refrigerant circulating in a cold air generation system. An ice-making pipe is installed within the ice-making unit and has the refrigerant flowing therein. A refrigerant pipe is installed in the refrigerator main body for receiving the refrigerant from the cold air generation system. A flexible pipe is disposed around hinged end portions (e.g., corners) of the refrigerator main body and the door and configured to interconnect the ice-making pipe and the refrigerant pipe in an extendable manner. A control valve can cut off a flow of the refrigerant flowing between the ice-making pipe and the refrigerant pipe, for example when the door is to be removed for repair or replacement.

Apparatus and method for heating/cooling buildings and other facilities. An elongate pipe filled with water or other fluid medium forms a thermal gradient header having temperature zones that are progressively warmer towards one end and cooler towards the other. Multiple heating/cooling systems are connected to the header so as to draw fluid from zones that are closest in temperature to the optimal intake temperature of each system, and to discharge fluid back to the header at zones that are closest to the temperature to the optimal output temperature of each system, allowing each heating/cooling system to take advantage of the thermal output of other systems. The pipe forming the thermal gradient header may be routed back and forth in the facility to define a series of legs containing the different temperature zones. A boiler or other source may supply makeup heat to the thermal gradient header, and excess heat may be sent from the header to a ground field or other thermal reservoir for later use.

The invention relates to an energy system, and more particularly to an air conditioning system for air conditioning rooms, comprising an energy source for heat pump systems, in which energy and/or heat is stored in a latent energy or heat storage system, comprising an ice slurry production device (100) for producing ice slurry from a liquid ice slurry brine (10), which operate according to a method for air conditioning rooms, in which energy or heat is stored or buffered in a latent energy or heat storage system and/or removed or extracted therefrom, wherein ice slurry is provided as the latent energy or heat storage system, or according to a method for producing ice slurry from an ice slurry brine (10), comprising the following steps: filling a housing (110) with the liquid ice slurry brine; cooling the liquid ice slurry brine by bringing it in contact with a heat exchanger device (220) disposed in the housing (110) while stirring the ice slurry brine (10) so as to generate the ice slurry, wherein, when an ice layer forms on the heat exchanger device (200), cooling is interrupted as soon as the ice layer reaches a predetermined thickness, and cooling is continued as soon as the ice layer drops below the predetermined thickness.
